As far as I can tell, temps are not the issue. The CPU doesn’t appear to go over 70C, and the GPU rarely goes over that as well. The junction temps get pretty hot, but stay under 100.
The performance is also pretty bad immediately after booting or waking up when it hasn’t even had time to heat up. And until this issue happened, everything was running fine for months.
I’m running a 240mm AIO and the fans are working fine, and CoreCtrl is reporting 5.0 to 5.1 gHz
It’s idling at about 51C, which I think is pretty decent for this chip. When I first put the PC together, it was idling around 60, but I think the waterblock and thermal paste settled, and the temps stabilized.
