|Platform||PC||OS||Windows||OS Version||Pro SP1 x64|
|Product Version||4.46 beta|
|Target Version||Fixed in Version|
|Summary||0001934: Fans not controlable / overridden on Dell Precision M4600 mobile workstation|
|Description||Starting SpeedFan 4.46 Beta 2 as administrator, FAN1(CPU) and FAN2 (GPU) both appear and read RPMs correctly.|
However, setting the automatic fan speed sets the fans at the proper speed for about one second, then go back to their original, system/BIOS managed, speeds.
|Steps To Reproduce||- On Win 7 Pro SP1 x64, start SpeedFan 4.46 beta 2 as administrator|
- Configure -> Speeds -> Set both fans at 33%
- Activate "Automatic fan speed"
- Both fan rev up from 0 RPM to the selected speed for about a second, then go back to 0 RPM.
- The machine then resumes its usual fan cycle management, alterning between 0RPM and 2600RPM cycles instead of the smooth, continuous SpeedFan speeds.
|Additional Information||Fan1 and 2 addresses : $3E8|
I can see the values changing properly in Speed01 and Speed02 on the Readings tab, but it has no effect on the fans, which remain at 0RPM (or 2600RPM, as usual..).
