I was having a bit of trouble keeping my non-overclocked 1800 cpu under 60C a while back, and today upgraded the fan from a Volcano 6 to a Volcano 9. The fan is much bigger and blows tons more air than the old one, but the temps still remain right around 60C. This is with the Volcano 9 running full blast as the default setting, no sensors involved. I verified the rpm's with MBM 5. I'm totally dumbfounded as to why I can't keep my temps normal. It seems most of you have much lower temps than I do, even some overclocked chips run cooler than mine. The fan is installed properly, square and snug on the cpu. I'm only using a thin layer of grease, just thick enough to coat the metal ID tag on the top of the cpu. Any thoughts or advice is welcome. Thanks.
