That's a very cool hack, but there are tons of things on a system that aren't the CPU that would benefit from some moving air. A fan somewhere in the system that just moves a bit of air would, I think, really contribute to the overall longevity.

Would be wicked if it was one of those passive cooling systems that create movement of air just via temperature differentials

That wouldn't necessarily be silent though.

		Passive convection flows would not be audible.

		It’s more likely to be quieter than a fan.

phones and iPads are similar and can get fairly hot, and they last a very long time if you replace the battery occasionally.

Phones and tablets are designed for passive cooling. And not always well to boot, but you can at least assume they didn’t design for elements with ancillary active cooling.

I don't think there are power supplies in an iphone that need to output 120W.

It's the temperature that matters here, not the wattage.

		The one tends to cause the other. There aren't any FETs anywhere in an iPhone that are passing 100A continuously. In any case, it's designed for that situation, whereas the Framework Desktop is designed under the presumption of the presence of a fan.

This is pretty cool. His design seems to be able to handle the full iGPU loads too:

His trick is to use a number of heat pipes (that transfer the heat through vaporization), and a really really big heat sink (a 5kg copper plate).

Which goes to 76°C if you run the PC at full load for a couple of hours. I prefer a little noise than burning myself.

76 is bad? My AMD Ryzen 9 7950X CPU frequently touches 90C whenever I play games or do heavy load stuff.

The whole black part of the case is for cooling if I understand correctly, so compared to your computer where the CPU can reach 90+ but the case stays at most warm, there the whole case reaches 70+ degrees.

It would be 70+ at the die. The heat would dissipate. It would be hot. But not 70+ degrees hot.

Oh damn yeah that's a whole different thing. Can easily heat a room with it during winter.

		Maybe a really mild winter; it's the same power as when I had my overhead light (2 60W lightbulbs) on in my room as a kid, and that didn't heat my room all on its own.

		It's dissipating the same amount of heat as the same CPU with fans. The difference here is the heat is inside it instead of blown out into the air.

		With the (mild) winter here I heat my home office room just with my 34.5" display, and it draws 45W ^^; (well, and my body heat)

The CPU is at 99, the case is at 76.

Thanks! I love Noctua but this is even more interesting than the article here.
