I have a z370i with an XMS profile at 3200mhz. I'm going to try that, thanks for the advice. I reinstalled the NH-L9i 3 times, and the spread pattern of the thermal paste seems fine... maybe I was just very unlucky with the cpu lottery.
I've tried a home-made duct and seen 3° improvement. I will try the Cryorig c7, but really disappointed atm. I bought the i5 8400 just to be safe with the temps lol
I'm having problems with my rear installed m2 970 evo. It gets really hot, in gaming the max temperature I've seen is 75°. Do you guys know any solution abut this issue?
