I think he was referencing an earlier post of mine. Obviously there is a convergence point the closer to idle temps eventually...

No does not work in any games except if they support DX12/Vulkan mgpu from the developer side.

Just picked up one of these (AsRock brand) and it seems like a decent card, especially for double precision compute. BUt daaum, this junction temperature thing is frightening... 103C and higher? WTH?

If you're not going with water and although I don't have one, I've been following this thread and two things you can try right off the bat is tightening the back bracket (screws may not be tight enough from the factory) since it may not be putting enough pressure between the thermal pad and GPU chip and undervolt while maintaining the same clocks.

Thanks. I have it undervolted during DP loads, fans at 100%, the gpu core is reporting a reasonable 65-ish degrees... with a junction temp over 100C. Hard to find any real info on this value. It does not seem to be a specific sensor, but an aggregate value of some sort?

Highest temp on the die somewhere being picked up by a sensor that remains a mystery. It's still baffles me why AMD did this which affects the clocks but since it's a pro card in reality I guess that is why for server longevity.

AMD placed 64 thermal sensors on the die since it's a 7nm die. The thermal density is higher than previous generations. Vega 10 also had 32 temperature diodes on the die which was called "Hot Spot." The Radeon VII will start throttling when the junction temperature reaches 110 degrees Celsius. I bought my card with the intension of water cooling.

It's clear why they added a junction sensors, it's to prevent the card from cooking itself since it would if they weren't there.
