I undervolted my 5800X3D and 9800X3D and that helped with temps a lot.

I never undervolted my GPU, I generally go the other way with it. My 4080 lost the silicon lottery, couldn’t get any more out of it. Not sure if I won it with my 5080 because a lot of people seem to be having large gains, but I got my boost clock to to a little over 3 GHz and a +1GHz to the memory.
