Hi all... Before the New Year hols, I bought a new CPU Fan assy, this one:
http://www.overclockers.co.uk/showproduct.php?prodid=HS-075-ZA
The description says it has a 4-pin connector, but I was mildly disappointed when I received it to find it has a 3-pin. I asked on retailer's forums and with customer services and was assured that I could fit a 3 pin fan to a MB 4 pin connector, and that fan-speed would be controlled by voltage, instead of by PWM
I went ahead and fitted the fan.... And now I have, as I feared, a horribly noisy fan which runs at its full speed and noise. Now, I have looked around in the BIOS, and tried enabling and disabling Q-Fan control and Cool 'n' Quiet.I have changed the voltage and temperature thresholds. Nothing slows the fan.
The sensors in the BIOS are working. If I slow the fan by braking it with a finger, the RPM figure changes. I honestly cannot work out what might be wrong here... Can anyone advise?
ps, In openSuse linux, and in Parted Magic Live, lm_sensors sees the sensors, including the fan RPM. I don't usually use Windows, but have the tech preview of MSWin 10. Speedfan, again, sees and reports the temps and fan speeds, but I can see no way to change them. It sems to me that if I can't manually affect the speeds whlst at the BIOS stage, then OS tools won't either. My MB is an old M2N-MX, with an Athlon 2 64 5600. The BIOS is version 1004, the latest they released (in 2008!). I have tried running the board with the fan disconnected... (don't try this at home folks!) with the expected results, although the temps reported by OS were not very high before the crash (below 60 deg C).
Could it be that the MB has ALWAYS run its CPU fan at full? The stock AMD cooler was 4-pin, I assumed that it being a bit noisy was normal, as it is
a) stock fan
b) very old
c) been running for two years of its hard life in an open cardboard box, and full of cat hair, dust, dearest comrade-ash and other detritus
The new fan is (subjectively) even noisier!
