Rigit :
I've recently upgraded my system. I am using an AMD PhenomIIx4 3.0ghz black edition. I've started toying (slightly) with OC'n. MB I'm using is a gigabyte GA-MA785-US2H My concern is cpu emps. The cpu cooler I'm using is not top of the line by no means but it should be adequate. But my cpu temps without oc'n are 68-70C according to the motherboard hardware monitor. A modest oc with multiplier set at x15.5 yields a clock of 3.1ghz with no increase in temps. I guess my biggest question is what's the highest temp I can expect to remain stable at? I'm going to need a better cooler I know but for now.
Hey, I too got the same mobo but a different processor(Phenom II x4 920).
I too was too much concerned about my temps cuz when playin GTA IV, it used to reach 66* C. I bought a new cooler, not top of the line( CM Hyper tx3).
Now, i've OC'ed to 3.4 Ghz and the temps are stayin @ 63 max and my idle temps are 50.
According to AMD's website, the max temp. of your processor is 62* C.
Have you applied Thermal Paste before installing the cooler? Which is your cooler? What type of a case have you got? Try uploading some pics.
