Some googling around finds this AMD document: http://www.amd.com/us-en/assets/content_type/DownloadableAssets/Cool_N_Quiet_Installation_Guide3.pdf which says: All AMD Athlon 64 Processor-In-A-Box packages include thermally controlled fans. A thermally controlled fan detects the current temperature of the processor using a thermistor, and when a lower temperature is detected the fan speed and noise is then reduced. Upon detection of a higher temperature the fan speed is resumed at full speed to appropriately cool the processor.
I was (trying to) build a quiet computer.I've first used the heatsink sold with the processor (the one with theorically the thermistor). It run full speed (3000 rpm) regardless the processor temperature. The procesor was running about 29C idle and 51C during burn tests.
Then I've used fancontrol to use the pwm capabilities of the motherboard. The fan was stopped when I stared the computer, full 3000 rpm at full load and 1200-1800rpm most of the time.
I remarked that I began to hear it at about 1500 rpm.I bought a Zalman CNPS7000B. I don"t use anymore fancontrol and I use the fanmate potentiometer to adjust it at the lower possible speed which is about 1300-1400rpm. The temparature are the same as with the stock heatsink at 300rpm (idle temperature is 3C higher) and the system is quiet...
Now, I've managed to increase my CPU temp ~20F, yet the CPU fan speed has not increased... and it's the funny-looking Cool'n'Quiet fan/heatsink which came with the CPU. Is 108F just too cool for it to do anything? [The MB does have a PWM driver, but the MB manual insists Cool'n'Quiet is something different.] I guess I really shouldn't worry, though, as the CPU normally runs at ~84F, and its nice and quiet...
