cooling

Tony Heller argues that US thermometer data shows a century of cooling and that NOAA adjusts the record to produce a warming trend.

Linus Tech Tips argues that big air coolers beat AIO liquid coolers for most PCs. They compare quietness and temperatures, using the Noctua NH-U12A as the example.

Linus Tech Tips water-cools a 2020 MacBook Air, tearing it down and showing the cooling design along the way. The video shows the gap between the CPU lid and die and how little the stock heatsink does.

Matthias Wandel uses anemometer measurements to find where to place a fan to move the most air through a house at night. He finds that placing the fan some distance back from the window works better.

Der8auer tours Hetzner's test lab and shows a custom AM5 server motherboard with the CPU socket rotated 90 degrees, built for rack airflow in their AX52 servers.

Scott Manley analyzes the idea of putting data centers in orbit, prompted by Lumen Orbit's funding. He examines the claimed advantage of constant solar power against launch cost, cooling and mass.

Louis Rossmann opens a new MacBook Air and reacts to its cooling design, where the fan does not appear to be thermally connected to the CPU heatsink. He calls it placebo cooling.

Kirsten Dirksen profiles Steve Rees, who buried two shipping containers to build an earth-cooled, off-grid 640 sq ft home in Northern California for about $30,000, solar included.

Linus Tech Tips opens up an M1 MacBook Air to test whether better thermal pads could improve performance in the fanless design. It looks at what Apple left on the table.

Technology Connections explains why single-hose portable air conditioners are inefficient and often a poor choice compared with window units. It details how the single hose pulls in warm outside air and wastes energy.

Veritasium debunks common climate change myths in under seven minutes, with references to NASA and published research. Topics include CO2 sources, sea ice and 1970s predictions of cooling.
