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.

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)

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.

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.

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