I feel silly not tuning my 7800X3D for lower temps, it's getting so hot so I went ahead and added a thermal limit at 70C°, offset -0.015 on vcore, offset +150mhz on operating freq, and I'm shocked that the performances are basically the same but it's running 12C° lower than before and quiet. This is on top of the CO -22 all cores I was already running, and stupidly thought that was the only thing you could tune on this CPU.
I'm posting this here because I wish someone told me this was possible. You can do all this directly on the bios.
