| Summary | 0001389: Steps in automatic fan control too big | ||||
| Description | Hi, I face a quite annoying issue with my Aopen HTPC (MP-915B, Winbond W83627THF). The software controls the CPU fan quite well but the steps between the different speeds are not fine enough: 0% - 4963 RPM 1% - 4963 RPM 2% - 4963 RPM 3% - 4963 RPM 4% - 5114 RPM 5% - 5114 RPM 6% - 5114 RPM 7% - 7031 RPM (this is where the noise starts) 8% - 7031 RPM 9% - 7031 RPM 10% - 7031 RPM 11% - 7031 RPM 12% - 7031 RPM 13% - 8036 RPM (max) Everything above 13% lets the fan rotate with its max RPM. Now, I would like to have more smoothly control over the RPM, especially in the range between 6% and 7% (where the noise starts). I played around with the configuration, but couldn't find a way to make it work. Any ideas/suggestions? Thanks, jose69 | ||||

Did you check CONFIGURE / OPTIONS / DELTA FAN SPEED? |
|
|
Thanks for responding! The delta fan speed is set to 1. |
|
|
It might depend on the fan response to PWM control, or on the circuitry on the motherboard. You might try to enter CONFIGURE / ADVANCED and choose a different PWM CLOCK. |
|
|
Unfortunately, out of 3 PWM CLOCKs, only PWM2 works. Any other idea? |
|
|
What do you exactly mean? That other settings are not applied? |
|
|
I see 3 different PWM modes, 1 to 3. Only PWM 2 shows some effect when configured to "manual PWM control". Any change to PMW 1 or 3 doesn't change anything. |
|
|
I just gave 4.39 a try and this issue is solved! Great work! |

Thank you for the update. |
