heat

With the heat in Andalusia, my PC is crying out for a new cooling system. These are the ones I like the most

by

It’s not June yet, but it’s already hot. Inside my apartment, since the sun is shining all day, it is very noticeable. This, of course, doesn’t help my PC, which starts making a hell of a noise because of the air cooler I have mounted. I wanted to change the box alonebut it will also fall a new cooling for the processor: this one from Corsair that is discounted to 91.99 euros. CORSAIR Nautilus 360 RS Liquid CPU Cooling – 360mm AIO – Low Noise – Direct Connection to Motherboard – Intel LGA 1851/1700, AMD AM5/AM4 – 3X RS120 Fans Included – Black The price could vary. We earn commission from these links Easy-to-install liquid cooling without lights There are several reasons to choose this Corsair cooling. The first of them is that I have several things from this brand at home and they all work great for me. The price is also quite attractive, because although we have had it cheaper on other occasions, right now it has a discount that makes it a very interesting quality-price option. Especially if, like me, You don’t want it to have those additions that increase the price (RGB lighting, I’m looking at you). I search an AIO liquid cooling (that is, not a personalized one, which is very expensive) that is simple and does its job very well. This Corsair Nautilus fits there very well because it has a 360 millimeter radiator with three 120 millimeter fans eachso we can expect very good cooling for the PC CPU. Another key thing for me is that it makes little noise and it does not exceed 20 dBA, although the speed of the fans is adjusted depending on what your PC needs at all times. It’s easy to install and is compatible with both AMD and Intel processors, making it suitable for almost any user. It does not have RGB lighting or a screen in the pump areabut I think that’s great: they are additions that are good, but they make the product more expensive. There are other options within the Corsair catalog and from other manufacturers, but quality-price, I think this Nautilus is one of the best we can buy right now. Other liquid cooling that is on sale CORSAIR iCUE Link Titan 240 RX LCD Liquid CPU Cooling – FlowDrive Cooling Engine – Intel LGA 1851/1700, AMD AM5/AM4 – 2X RX120 RGB Fans – iCUE Link Hub Included – White The price could vary.

The heat is uncovering one of the biggest problems with smart rings

by

A quarter of a century ago (seriously), Sonia and Selena sang that “When the heat comes, the boys fall in love.” Today we can add one more phrase to the song: your hands swell and, if you are wearing a ring, forget to take it out. If it is also a smart ring, with its sensors and lithium battery, we have a problem. This is what many users are discovering. This is tight. If it is hot and we also start exercising, it is quite common for a small swelling to occur in the hands. That’s exactly what happened to him to this journalist when he went out for a route through the forest: shortly after starting, he felt how the ring began to tighten more than necessary and he had to take it off. In the case of a watch or bracelet there is no problem because we can loosen it, but the rings are completely rigid devices, often made of metal, and with a thicker design than a conventional ring so they end up being more annoying. The effects of heat. When the temperature begins to rise, blood vessels dilate to release heat, causing more fluid to leak into the tissues. The areas where it usually ends up accumulating are hands and feet due to the effect of gravity. It is what is known as heat edema and it is quite common in the summer months or when we exercise. Not only do the fingers swell. The battery can also expand due to a defect or heat itself, making the ring feel smaller. This Oura Ring user He noticed that as time went by his ring felt tighter and the battery also lasted much less. When he contacted the brand, they confirmed that it was a battery problem and they ended up changing the device. There is more similar cases on Reddit. Miss a plane. The case of youtuber Daniel Rotar It is perhaps the most striking of all. The battery in his Galaxy Ring began to swell causing the ring to get completely stuck on his finger. It hurt and there was no way to get it off, not even with soap and water. As if that were not enough, Daniel was about to take a flight, but was denied boarding because the ring’s battery posed a security risk. He ended up missing his flight and had to go to the emergency room to have the ring removed using ice and lubricant. What companies say. Samsung has a help page with tips on how to remove a Galaxy Ring in case it gets stuck on your finger. They suggest using soap and water, dipping your hand in cold water, or holding your hand up high. If none of this works, they recommend going to the emergency room and having them cut the ring, even indicating the points where to cut so as not to damage the battery and which could end up causing burns. In the case of Oura They also offer the same advice and a guide to know where to cut if necessary. Rethink the design. Smart rings are sold as the solution to monitor our health with an ultra-compact design and more comfortable than a watch, until it gets stuck and you have to cut it off, of course. In this sense, perhaps the future of this product involves sacrificing that rigid and continuous aesthetic, giving way to open designs that can better adapt to these natural changes in the body. It is a path that the company has already started Movano with the Evie ring. Image | Xataka In Xataka | Best smart rings 2026. Which one to buy based on use and six recommended models

What until recently were small incursions of spring heat have turned Europe into hell

by

London at 35 degrees in the month of May. We are talking about a record that would be exceptional in the middle of summer. France (“a country where much of its territory is low, soft terrain of little relief”) dangerously close to 40 and discovering how all those cities in the valleys They become “pans like Seville or Córdoba”. Central Europe, the Alps, the former Yugoslavia seeing how the thermometers have gone completely crazy. “Literally hundreds of May records have already been beaten“and the worst thing is that no symptoms are seen weakening on the horizon. The relevant question today may be why. What is happening? “It will never cease to surprise me to see a number (…) so extreme for the time and covering such a large record area,” said González Alemán a few hours ago. And no wonder: each of the little pink dots in the image below are historical heat records for May. This week, Europe has become hell and, despite years of warnings, no one really expected it. How is it possible? The explanation is simple. A powerful subtropical anticyclone has spread over Western Europe and is generating what It is often referred to as a “heat dome”. That is, a situation in which the air on the surface is not renewed, does not move and, as a consequence, warms up little by little. The following two maps show perfectly what this “heat dome” is and where it is affecting most intensely. What do they mean? The first image shows the size and extent of the anticyclone. Right now, much of Europe is cloudless. The second shows the intensity of the phenomenon. As Jeff Berardelli explainsany red dot represents a new record for May (and we are taking the record since 1950 as a reference). This has many names… “atmospheric blocks”, quasi-resonant amplification of planetary waves either persistence of “double jet” configurations about Eurasia. But the result is the same: the problem has stopped being the heat and is starting to be that today’s climatic extremes continue for days and days. “This is perhaps the most obvious sign of the new climate that has nothing to do with that of a few decades ago”. And what can we do? That’s a great question, because these heat waves (if, as they seem, they persist) will have a very clear consequence: Europe will have to change its real estate stock from “houses designed to keep the heat out” to “houses designed to keep it out.” We are facing one of the Image | Tropical TidBits In Xataka | The Gulf Stream is dying.

It is 1,000 times faster than current semiconductors and does not heat up

by

A research team at the University of Tokyo (Japan) has reached an impressive milestone in the field of semiconductors. And, as he has collected Nikkeihas developed a device capable of processing information 1,000 times faster than the current most advanced CPU. It seems like science fiction, it’s true, but it’s not. It’s just science. Of course, this is frontier science. And the non-volatile quantum switching device that these scientists have developed uses quantum physics to carry out its purpose. Most strikingly, this device represents bits using the magnetic properties of electrons rather than the flow of electricity itself, which is what the integrated circuits we are familiar with do. In fact, its capabilities lie precisely in this strategy. Current semiconductor technology It takes about a nanosecond to register a single bit before overheating becomes a critical issue. However, this innovative device processes one bit of information in just 40 picoseconds. In practice this means that you invest one thousandth of the time in this process that conventional methods require. Interestingly, it combines tantalum and manganin to convert electrical signals into magnetic information, so its composition is very different from that of the silicon chips that reside inside our electronic devices. Heat is no longer a problem Laboratory tests carried out by researchers at the University of Tokyo have yielded surprising results. In their ingenious device, an electrical signal passes through the tantalum layer, so that the device registers that signal in the manganin in the form of the direction of a tiny magnetic force. Precisely this address represents a single bit without depending on the continuous flow of electric current. Its performance improves as components become physically smaller During the first tests, this device has worked completely stable even after processing information more than 100,000 million times. However, these Japanese researchers have verified that their performance improves as components become physically smaller. For this reason, if this technology finally makes it out of the laboratory, it could reduce energy consumption when processing information to just one hundredth of current levels. Here’s another impressive fact: this device has processed information 100,000 million times without making a mistake. However, a current CPU or GPU would have overheated after just 10 million clock cycles if it had run at a similar speed. There is no doubt that it is a notable achievement. Be that as it may, we cannot ignore that moving this technology from the laboratory to a chip factory is a real challenge in the field of engineering. The physics works, as these Japanese scientists have shown, but large-scale manufacturing poses challenges that are not present in a single device produced in a university laboratory. Even so, Disruptive technologies are usually born this wayso although the future of this innovation is uncertain, there is a possibility that it will manage to leave the laboratory and reach the chip manufacturing plants. The prototype is planned for 2030. Fingers crossed. Image | Satoru Nakatsuji (University of Tokyo) More information | Nikkei In Xataka | China has reached one of the holy grails of quantum physics.

Oviedo has already broken its heat record for May and AEMET warns that this has only just begun

by

Let’s stay with a figure: 34.3. It is, almost certainly, the most important data of the week. On Thursday, May 21, 2026, the thermometers of the city of Oviedo They recorded a temperature of 34.3 degrees. 1.8 ºC more than the highest temperature ever recorded in May in the capital of the Principality. AEMET is convinced that between today and the weekend will be reached again (or even exceeded) this temperature. And yet, this is only a tiny part of the story. Because the real story is that, in a region structurally protected by its oceanic climate, records are being broken in ways we would not have been able to imagine. And that’s without the country being in a ‘heat wave’. What is happening? Although There is some controversy with the namewhat is happening is called ‘heat dome‘. That is, a subtropical anticyclonic ridge, anomalously powerful for this time of year, which is trapping very warm air above our heads. Europe is bearing the brunt, it is true. Countries such as France, Germany, the Netherlands and the British Isles they are seeing temperatures between 10 and 15 degrees above normal. If everything goes as predicted by the models, the May records of half of Europe are going to explode on the 25th of this month. And, of course, we are noticing that. As the haze falls on the Canary Islands (right at the eastern vertex of the dome), a good part of the country will suffer considerable heat. We talk about more than 34 degrees in Asturias and the Basque Country and 38 in the Guadiana valleys. The Guadalquivir valley is already above 35. And, as I say, all this without heat waves. Despite the magnitude of the episode, AEMET does not rate it like a heat wave in peninsular Spain. It is not. We already know that the operational definition requires exceeding the 95th percentile of daily maximum temperatures for the July-August quarter for at least three days and, of course, we are not going to go to that extreme. What does all this heat tell us? Let’s be honest. For Andújar or Badajoz to reach 38 degrees on May 21 is rare, but not exceptional. But for Oviedo to reach 34.3 is a very different thing. It shows, above all, that the Cantabrian coast is beginning to stop being a “climate refuge.” Why is all this important? In addition to an underlying climate issue, this warm episode is important because it is dangerous. The first extreme heat of the year is the deadliest because the population has not gone through the period of physiological acclimatization produced by progressive exposure to summer heat. That is, because it is May and the Iberian summer has truly begun. Image | Tropical TidBits In Xataka | The Gulf Stream is dying.

Spain is going from pre-spring weather in one week to “African heat” in the next

by

It’s been cold. The first half of May has been marked by negative thermal anomalies of up to 10 degrees below normal, but that is over. According to the modelsthe entry of an anticyclonic ridge of Saharan air is going to revolutionize the Spanish meteorological situation in a matter of days: on Friday the 22nd the forecasts indicate July highs. We are talking about 36-37 °C in the Guadalquivir and Guadiana valleys, more than 30 in the entire southern half of the peninsula and, keep an eye on the data, the first tropical nights of the year. I mean, things are getting serious. What is the news? The protagonist of this week’s story is once again the polar jet. However, instead of a cold air mass, the undulations of the jet will place a warm African ridge above our heads. The process It will begin on Tuesday the 19th and will last until at least the 22nd.. After Friday, the models mark the appearance of a DANA in the Cantabrian Sea; However, it is too early to say precisely. What is going to happen? Let’s go in parts: Between Monday the 18th and Tuesday the 19th It is going to recover progressively. 30 degrees will appear on Tuesday in the Ebro valley, the interior of Murcia and the southern half of the Valencian Community. He Wednesday 20 The 30 will arrive in Madrid, Extremadura, Castilla-La Mancha, the interior of Andalusia, the Region of Murcia, the Ebro valley and the interior of Catalonia. Sevilla will score 33-34 without problems. He Thursday 21 in the Guadiana and Guadalquivir valleys 34-36 °C will be reached. 36 are expected in Seville, 35 in Badajoz, 34 in Toledo and 32 in Madrid. He Friday the 22nd All of Spain will be above 30. Only the Balearic Islands, the Canary Islands, Galicia and Asturias are spared. That day we will experience the first tropical nights of the year on the southern plateau and the Guadalquivir valley. That is, the thermometers will not drop below 20 degrees. Is it something strange? Yes and no. What’s interesting about this episode It’s not the heat itself.. We have already seen Mays like this recently. What is interesting is the magnitude of the swing: we are going from anomalies of -10 °C to anomalies of +10 °C in a single week. And this is something that neither the human body nor crops assimilate easily. Image | BenBaso In Xataka | The Gulf Stream is dying.

In Barcelona they did not drop below 19°C on an April night. And that’s more important than all the heat waves

by

It’s one piece of information, just one. But he alone weighs more than all the daytime maxims combined. Barcelona-Fabra just broke the record of a century with a nighttime minimum in April above 19 degrees. And yes, 19 degrees seems little compared to the 33-35 that the Guadalquivir Valley experienced that same day in the morning; But if climate change has been teaching us something for decades, it is that appearances can be deceiving. That anomaly called ‘April’. Although it is not being as scandalous as January, April is breaking all historical records. The fact that has been repeated the most is that AEMET has recorded more than 70 records temperature only in the first time of the month. In aggregate terms, we are talking about a sustained thermal anomaly of between 5 and 10 degrees. And it is interesting because, although it is evident that we are not talking about a ‘heat wave’, experiencing an anomaly of this size in this context is something tremendously revealing. Not only because they are the temperatures that most affect the population’s rest, but because they are the ones that rise the most due to the effect of climate change and the ones that best explain where the country’s climate is going. But what has happened? On April 10, at the Fabra Observatory in Barcelona, ​​at the foot of Tibidabo, the minimum it did not drop below 19 degrees. That is, it is the warmest night in at least a century. And it was not an isolated event: the ALmería airport registered a minimum of 23.3 degrees that same night. That’s two degrees higher than the previous record. The month, as I said, has had more than 70 temperature records. AND, according to Duncan Winger of Tiempo.comwhat awaits us between the 18th and the 24th looks to be much worse. The explanation is simple… because it arises from two combined elements: a subtropical ridge installed on the peninsular vertical that blocks the arrival of Atlantic storms and a very warm air mass from the south that causes little relief at night. …but the fact that it is ‘explainable’ doesn’t reassure anyone. Above all, because we come from 9th warmest winter on record and an especially hot February with an anomaly of more than 2.4 degrees above average. Everything seems to indicate that the meteorological data show the structural warming that the models indicated. But… what can we expect from all this? First of all, be clear that nights are becoming a problem. Without leaving Barcelona, We know that mortality from natural causes in the city it increases up to 9.2% on nights when the temperature does not drop below 23 degrees. There are more consequences, of course: a good part of the country’s agriculture is in critical phases and the Mediterranean is getting so hot which is going to cause innumerable problems. But warm nights before HVAC systems are turned on are a public health risk that is difficult to control.

heat records in Spain have doubled

by

Every summer in Spain seems to bring with it the same refrain and we repeat several times “this is the hottest day I can remember.” And although sometimes memory deceives us, statistics and mathematics have confirmed that It is not a subjective sensationbut breaking the thermometer year after year has become normal. And it is more common in some specific regions of our country, such as has collected El Confidencial in an interview with the researchers. The data. This has been determined by a team of researchers from the University of Zaragoza who has analyzed data from the State Meteorological Agency between 1960 and 2021. What they were able to observe is that the frequency of breaking a high temperature record has multiplied by two due to global warming. The interpretation. In the published article by these researchers, they are not limited only to counting hot days in a specific time range, but they developed a mathematical tool first level to have very reliable conclusions. And, instead of looking at weather stations in isolation, the team has created a Bayesian model using MCMC (Monte Carlo Markov Chains) methods. This means that they designed an algorithm that is capable of understanding how temperatures are related in space throughout the entire Spanish geography and in time during the period of more than sixty years that they have analyzed. An advantage. This system allowed them to filter out the statistical noise that exists when we interpret these data in a raw manner. In this way, they have processed data from more than 40 locations in mainland Spain and have found out not only how many records have been broken, but how many would have been broken if climate change did not exist. The result is that today we see twice as many records as would be expected in a stable climate. High heat areas. The spatio-temporal model has not only produced a national average, but has also made it possible to map extreme heat with astonishing precision, pointing out that the impact of climate change is more pronounced in specific areas of Spain. In this way, if we look at Spain in general, the frequency of thermal records in the last decade is almost double what is normal. But if we specify much moreareas such as the Northern Meseta, in the area of ​​Madrid and part of Castilla y León, and especially during the summer, have tripled the record data in their historical series, which is well above the national average. A prize model. The great work done by this group has not gone unnoticed, but has managed to win different awards, such as the award for the best applied contribution in statistics. But beyond recognition, the researchers have left a “gift” to the scientific community by leaving the model completely open in R. This means that climatologists and data analysts around the world can download their code and apply it to predict and model the breaking of thermal records in other regions of the planet.

The molecule that stores the sun for years and releases heat just when you need it

by

In winter, raising the blinds to take advantage of the light and heat of the sun in the central hours of the day is a good idea to heat the house while saving on heating. Of course, as the afternoon passes and night falls, goodbye to the sun and its heat. From an energy point of view, it would be fantastic to be able to store the sun in a bottle to release its heat when needed. Something like this has occurred to a research team from the University of California in Santa Barbara, which has published its research in Science: a molecule that captures sunlight, stores it for years without loss, and releases it on demand. No plugs or batteries. Professor Grace Han’s group has synthesized a modified organic molecule inspired by DNA. It is called pyrimidone and is capable of capturing solar energy, storing it in chemical bonds and releasing it as heat in a controlled and reversible manner. In short, as if it were a battery. Context. The analogy of the bottled sun is for practical purposes one of the great problems of solar energy: the issue is not so much capturing it, but rather storing it because obviously there is not always enough sun to satisfy demand. And conventional batteries degrade, are heavy, carry inherent management risks, and are expensive (although now they are below minimums). What Han’s team is proposing is not new: molecular thermal storage, known as “MOST” for short, has been researched for years. However, until now no system had managed to combine competitive energy densities with release temperatures sufficient for real practical application. Why is it important. Because this research breaks two essential barriers that make MOST increasingly closer to being a reality: It has an energy density of more than 1.6 megajoules per kilogram, almost double the energy density of a standard lithium-ion battery. It releases enough heat to be able to boil water under ambient conditions. It is also soluble in water, which makes it potentially compatible with circulation systems in solar collectors. These properties open the door to uses such as domestic heating and domestic hot water (DHW), areas without an electrical grid or systems integrated into roofs. How it works. It is important to highlight that despite the analogies with solar energy, its mechanism is completely different from that of photovoltaic cells. Come on, it does not convert light into electricity, but rather it transforms it into chemical energy that it stores in its chemical bonds. The molecule, which was designed with computational modeling thinking about reducing it as much as possible, works as if it were a spring: upon absorbing ultraviolet light it undergoes a reversible change in its shape, passing into a high-energy state. The molecule can remain stable in that state for years until an external stimulus causes it to relax, releasing the accumulated heat. As Han Nguyen detailslead author of the article, “the concept is reusable and recyclable.” From Barcelona to California. The fact that the MOST have been in the laboratory for a long time is so true that in 2024 a team from the Polytechnic University of Catalonia published a paper in Joule on a hybrid device that integrated a MOST system directly into a silicon photovoltaic cell. The idea is that organic molecules (composed of carbon, hydrogen, oxygen, fluorine and nitrogen) act on the one hand by storing energy and on the other, as an optical filter and cooling agent for the solar cell. The molecules absorb the UV photons that silicon does not use well, cool the cell and store that surplus as chemical energy. Thus, the solar cell generates more electricity and nothing is wasted: the system achieved a solar utilization efficiency of 14.9% and a record of 2.3% in MOST storage. Yes, but. That two independent studies separated in time work on the MOST shows that this technology is more than a mere laboratory concept: it is getting closer to having real applications. Of course, like any other innovation, it faces the challenge of scalability and costs, essential for eventual industrial deployment.

how to dissipate heat in a vacuum

by

We call it a cloud, but in reality it lives on solid ground, more specifically in mammoth buildings with endless corridors, or that’s how it has been until now. The idea of ​​​​taking data centers into space It sounds increasingly louder and is presented as the solution to the insatiable energy appetite of artificial intelligence. In the midst of this growing obsession, the player who holds the key to all current hardware has just had a reality check. NVIDIA puts on the brakes. Google, Elon Musk, Jeff Bezos…everyone has talked about taking data centers to space. Even NVIDIA itself He has participated in projects of this type, but it seems that he has changed his mind. As published in BezingaDuring the company’s latest earnings call, Jensen Huang took the opportunity to lower short-term expectations for orbital data centers. dissipate heat. The idea of ​​bringing data centers to space was born from the need for energy. In space, energy is practically unlimited because solar panels can be receiving light all the time. The problem, according to Huang, is dissipating heat. On Earth, data centers use air or water for cooling, but in the vacuum of space there is no air. The only way to dissipate heat in space is by conduction to radiators which, in the CEO’s words, must be “quite large.” NVIDIA knows this well because already has a satellite with H100 GPUs in space. Why it is important. Huang’s intervention is relevant because NVIDIA is the main provider of the infrastructure that xAI, Amazon, Google and other technology companies need for their space plans. If the biggest beneficiary of selling chips for these projects warns about their viability, the market listens. Even so, his words have not been a complete refusal, but rather a “not yet.” Analysts agree. In a Gartner report to which he has had access The Registerclaim that companies are wasting money pursuing the dream of space data centers. Their argument is that orbital facilities are not profitable, but they also claim that they could not satisfy the necessary computing demand. In addition, it also highlights the technical challenge that cooling these structures in the vacuum of space would entail and another problem: the extreme temperature fluctuations that can go “from 100 degrees kelvin to 400 degrees kelvin” (between 126ºC and -173ºC). This would require the use of special materials and components, much more expensive than their terrestrial equivalents. Musk vs Altman. There is little that the CEOs of xAI and OpenAI agree on and data centers in space were not going to be any different. Elon Musk announced a megaproject with SpaceX and xAI to launch a constellation of one million satellites. At an event a few days ago, Altman called the idea ridiculous.although he also admitted that “it will make sense one day (…) we are not there yet.” In Xataka | Aragón is becoming a Spanish data center giant thanks to Amazon.
