| 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..). | ||||
