Listmates, I have a relatively new 11.0 box with a phenom 9850 that is fairly quiet. Recently I noticed the CPU fan noise quite a bit more than usual. I initially thought that fan control was going on the fritz. I checked the temps and fan speed with lm-sensors and confirmed fan RPM was pegged near max: CPU Fan: 5338 RPM CPU Temp: +33.0°C Weird, the temp was only 33 degrees, not warm at all, not even a concern. So I waited a while and checked back. The noise had dropped a little, but not much. It was still horrible: CPU Fan: 5119 RPM CPU Temp: +32.0°C The case has 3 120mm 3-speed fans, all set on low. One in the bottom by the power supply, one on the back in the normal position, and one that blows out the top through a screened housing. On a whim, I decided to step up the 120mm fan on the back of the case closest to the CPU. I set the fan control to medium where the 120mm fan is still quiet and waited. In less than 5 seconds the CPU fan noise started dropping fast. Within 30 seconds the CPU fan noise completely vanished. The box was for all practical purposes near silent. I checked the temps again: CPU Fan: 3282 RPM CPU Temp: +31.0°C That is absolutely incredible. Evidently the fan thermostat on the stock AMD cooler that comes with the processor has less than a 2 degree spread between its 3200 RPM low noise state and its 5200 RPM annoying as hell state. Moreover, the slight increase in the back-panel fan RPM from low to medium was just enough to provide the slight additional amount of airflow needed to drop the CPU temp by 1 degree and eliminate the noise. Just 1 degree made the difference between an pleasant quite box and a costly additional expenditure for a water block. That's it, ... I'm shooting the cats... -- David C. Rankin, J.D., P.E.
