my setup is 265k with a deepcool le360 AlO, under stress test the cpu is thermal throttling to 100%, and after stopping the test it still is thermal throttling somehow, how do i fix this? I have re-pasted 3 times with Arctic mx-6 and can feel the aio pipes vibrating a little which indicates the pump is working as well. Is it a case of needing to undervolt the cpu as well?
