arstechnica.com Unknown 2025-10-17 16:26:16

Despite its lack of upgradeable system memory, Framework has tried to make its Framework Desktop a welcoming platform for upgraders and modders, releasing 3D-printable versions of a few case parts and generally sticking to standard-sized parts and standard connectors. Often, it's independent creators who are making the weirdest and most interesting mods for Framework's devices, but PC cooling company Noctua has just announced what amounts to a fairly major cooling upgrade for the Framework Desk

The Best Cooling Sheets (2025): Brooklinen, Slumber Cloud, Buffy

There's a lot of terminology thrown around in the world of cooling sheets and cooling mattresses. Temperature regulating! Airflow! Moisture wicking! Phase-change material! Most of the time, these features come back to how breathable the sheets are. Breathability means moisture can better evaporate, and “temperature-regulating” usually means the sheets are breathable enough to release the heat and moisture from your body.

Bedsure's Bamboo Cooling Sheets Are Silky Soft, Durable, and Cheap

I’ve met many supposedly “cooling” sheets in my time as a mattress and bedding tester, and I have been disappointed more often than not. A cooling mattress can’t do all the heavy lifting with temperature regulation, and I’ll forever emphasize that your choice of bedding matters just as much—which is why I'm an unapologetic sheet snob. Which brings me to Bedsure, a brand I stumbled across on Amazon in a last-ditch effort to find some decent sheets when mine bit the dust (rather, my dogs bit holes

As the world has grown more connected, the demand for data centers has grown—and then along comes artificial intelligence (AI), with processing and storage demands that amp up the need even more.
