Popular PC Maker Reacts To Nvidia’s New RTX 30 Cooling Design

Nvidia’s new GeForce RTX 3080 Founder’s Edition graphics card ditches the “reference” style, single blower-style fan for a push/pull cooling solution. That much you already know. What you may find fascinating is that without any kind of thermal solution directly attached, a GPU like this would reach in excess of 750 degrees Celsius — about 100 degrees hotter than the melting point of aluminum. An Nvidia RTX 3080 inside a Falcon Northwest Talon PC Falcon Northwest So, cooling: it’s kind of important! You may also find it interesting that a GPU’s cooling design can directly impact the types of systems or options your favorite PC builds like Origin, Alienware, Maingear and Falcon Northwest might offer. In fact, Kelt Reeves of Falcon Northwest — the company largely responsibl...

L.A. suffered deadly heat, yet chairs sat empty at its cooling centers

Despite scorching temperatures that shattered official records and led to deaths on the street, many chairs ended up sitting empty at the handful of city cooling centers set up to spare Angelenos from the blistering heat. © (Al Seib / Los Angeles Times) The thermometer at Calvary Church in Woodland Hills registers 117 degrees during a heat wave last month. (Al Seib / Los Angeles Times) Fewer than 300 people used the six centers that were set up at Los Angeles city facilities over the Labor Day holiday weekend — averaging fewer than 11 visitors daily at each site, according to numbers provided by the office of Mayor Eric Garcetti. One cooling center in South Los Angeles had no one stop in at all on Labor Day or the previous Friday. Load Error Homele...

Comfort Tech Heating & Cooling employees love pups in the office – Think Local

Photo: Contributed Annabel and Murphy When customers visit the Comfort Tech Heating and Cooling office in Kelowna, the humans who work there are often overlooked at first. Much more attention is paid to the office dogs. Photo: Contributed Solo “Our customers love it,” Comfort Tech dispatcher Paula Broadhead says. “We have a gate, so they don’t have to come right in to the dogs. We always ask people if they’re OK to come in with the dogs, and most people just love it. “They spend time with the dogs before they get down to business.” While offices seem to be dwindling in the wake of COVID-19, the number of office dogs appears to be on the rise.

Can indoor air filtration protect you against COVID-19? Maybe | Local News

MERIDIAN — Like many other business owners in the Treasure Valley, J.P. Green decided he needed to make changes to reopen his business this spring, after he was legally able to do so, following historic closures meant to slow the spread of the new coronavirus.He owns and operates CycleBar Village Meridian, a studio that offers stationary bike classes. The risk of the spread of the virus was there, he knew, but he was legally able to open the business again in May. He took precautions: smaller class sizes, a contactless check-in process, a 30-minute window between each class for deep cleaning.Green said he wanted to go further in making the studio safe for customers and staff, so installed the REME HALO, an air purification device that attaches to the studio...

TipRanksGoldman Sachs: These 3 Stocks Are Poised to Surge by at Least 50%Is it time for the bears to break out the champagne glasses? Not so fast, says Goldman Sachs. Volatility has ruled the Street for the last few weeks, leading some to conclude that those with a more pessimistic outlook had been vindicated, but the firm believes stocks can still climb higher.According to Goldman Sachs’ head of U.S. equity strategy, David Kostin, the S&P 500 could still hit 3,600 by the end of the year, and 3,800 by mid-2021, on the back of vaccine-related optimism and progress with the economic reopening. This would reflect gains of 10% and 16%, respectively, should the index ultimately reach these targets.“Despite the sharp sell-off in the past week, we remain optimistic about the path of the U.S. ...

All-in-one design integrates microfluidic cooling into electronic chips

An energy-efficient way to improve the performance of electronics systems would be to integrate microfluidic cooling channels into chips, to prevent overheating. However, state-of-the-art microfluidic cooling systems have previously been designed and constructed separately from electronic chips, preventing the channels from being integrated into circuits to provide direct cooling at hotspots. Because such integration greatly increases the complexity of chip fabrication, it would potentially increase the cost. Writing in Nature, van Erp et al.1 report an electronic device designed to have an integrated microfluidic cooling system that closely aligns with the electronic components, and which is constructed using a single, low-cost process. Power electronics are so...

A New System for Cooling Down Computers Could Revolutionize the Pace of Innovation | Science

In 1965, Gordon Moore, a co-founder of Intel, forecast that computing would increase in power and decrease in price exponentially. For decades what later became known as Moore’s Law proved true, as microchip processing power roughly doubled and costs dropped every couple of years. But as power increased exponentially, so did the heat produced by packing billions of transistors atop a chip the size of a fingernail. As electricity meets resistance passing through those processors it creates heat. More processors mean higher temperatures, threatening the continued growth of computer power because as they get hotter, chips decrease in efficiency and eventually fail. There’s also an environmental c...

Advantages Of Low-Carbon Heating Over a Gas Boiler

Across the world, low-carbon heating systems are replacing gas boilers in an attempt to tackle the escalating climate crisis and provide a more sustainable and safe form of indoor heating. Although low carbon heating system does virtually the same thing as gas boilers, an important aspect of what they do is to lower the impact on the environment. According to Jenny Campbell at Prominence Support, a boiler cover provider ‘’For years, we have been dependent on fossil fuels such as oil, gas and coal to heat our home and water, and today, it accounts for as much as 30% of all energy-related carbon emissions’’, she continues ‘’By going with low carbon heating system instead of boilers, we could reduce carbon emissions drastically’’ but that’s just one part of it. 1.

Warmed Tunnel Air Provides Heating/Cooling Energy

Researchers at EPFL have calculated the benefits of a geothermal heat recovery system, using fluid-filled plastic pipes, for train tunnels. (Image source:  LMS / 2019 EPFL)Turning waste energy into useful work is becoming a trend. Now, researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL), a research institute in Switzerland, have proposed a way to capture the wasted heat energy in rail tunnels to provide heating and cooling to thousands of homes and municipal buildings.Trains produce heat that warms the surrounding air when they brake or accelerate. That hot air mixes with other air in the tunnel and with heat radiating from the ground. Even the body heat from the passengers adds to the overall heat energy that is pre...

Global heating played part in American mastodon extinction, say scientists

© Provided by The Guardian Photograph: Thomas Lohnes/Getty Genetic diversity could shrink as animals venture into new territories because of global heating leaving them vulnerable to extinction, scientists have warned after tracking the impact of climate change on the American mastodon. Huge, hairy and with a pair of fearsome tusks, mastodons resembled stocky, hirsute elephants. The earliest fossils of American mastodons date to about 3.5-4m years ago with the creatures commonly found in wooded and swampy areas where they browsed on trees and shrubs. © Photograph: Thomas Lohnes/Getty An American mastodon skeleton excavated in the Hudson River Valley, New York state, in 1801. But by 11,000 years ago they were extinct – probably, experts say, because of a combination ...
