Summary0001887: Can't adjust CPU fan speed; Case fan showing 0 RPM
DescriptionI've tried changing a few of the settings in Advanced but nothing seems to effect the CPU fan speed. It's stuck at 1412 RPM, which seems low considering I've changed all 4 speeds to 100%.

The only time it changes is when I turn Q-Fan on in Bios, but it lowers it to 830 RPM. I have left it off.

I tried changing from Manual PWM Control to Thermal Cruise, Fan Speed Cruise and SmartFan 3. I also changed the FAN Divisors to a few different values with no effect.

Besides CPU0 Fan, Sys Fan, Aux0 Fan, CPU1 Fan and Aux1 Fan, are all showing 0 RPM.

I checked my case fan to see how many pins it had. It is 4, but it's one of the large ones connected straight to the power supply. Is that the reason it's not showing up?


I do have one case fan

A few notes:
1) may be your fan is controlled by a PWM that SpeedFan can't access
2) are you sure that the CPU fan could be slowed down by enabling Q-FAN?
3) try SpeedFan 4.45 beta 4. At the very least, you will gain a lot more readings (including the case fan, I think)

Ya when I enable Q-Fan, the speed drops to around 850 RPM, I've tried this a couple of times.

When Q-Fan is not enabled, the speed sits around 1400 RPM

The beta adds 2 more readings.

The first is CPU which appears to be identical to CPU0 Fan. Their RPM fluctuations are identical.

The second is CHASSIS, but it's reading 0.

Are there any settings in the Beta I should try changing?

Please, send me a SEND REPORT from the beta.
