CPU: AMD Phenom II x4 955
GPU: ATI RADEON HD 6850
It has the stock fan and thermal paste. I have Thermaltake TG-2 thermal paste, but I didn't use it because it was my first time build and I didn't want to make a mess. I have a closed case with a small fan of 80mm to blow air into the case.
The motherboard has 4+1 phases, support up to 140W and Low RDS (on).
I have been trying to undervolt and overclock the processor at the same time. Until now I have been lowering the voltage and running prime95 (blender test) watching for temperatures. After many tests, the last time I ran prime95 with 1,25V on the Cpu voltage and 3.4GHz (x17 multiplier). Cool n' Quiet upped my voltage to 1,26V. I ran stable for 1 hour and 10mins aproximately and then it crashed. My maximum temperature with prime95 was 54°C, but it was for a really short period of time, mostly it was at 52°C under load.
I'm afraid of blowing up the motherboard. Speedfan reports the following temperatures:
For what I've seen in internet: Temp0=CPU, Temp1=Mosfet, Temp2=NB. Are those temps dangerous? I just want to overclock the processor only. Thank you so much.
