I have a 955 3.2Ghz in my machine. Most of the time it is silent, and most of the time the processor is running under 25% anyway, with the cpu cooler fan running around the low 3,000s RPM. At that speed, it is pretty silent, but if anything cranks it up, it soon becomes audible, and at around 4,000RPM is produces an unpleasant whine. It is worse for the fact that the case fans only give airflow sound.
The AMD stock coolers seem to be noisy. My previous Pentium Core 2 Duo cooler was actually silent, but on that machine it was the case fan that made the noise!
Yes, the answer for both of us is to replace the stock cooler. I guess I'm going to go for something like this <
Scythe Yasya> eventually (means
when I get around to it!). I have a big tower case, so space is not a problem, but I still wonder about hanging such a weight off the motherboard! :sad: I guess people do.
