Hi,
I have an Asus X550L laptop which I've had for about 3 years. This morning when I switched it on the fan was constantly running at full speed and wouldn't slow down to a normal speed like it usually does. I haven't done anything to the laptop between yesterday, when it didn't do this, and this morning.
So far I've tried turning the laptop off and on again, and leaving it unplugged with no battery for an hour. I also checked if the fan had any device drivers, I found it doesn't appear in the device manager as a device and so it doesn't appear to have drivers. I also checked to see if windows had updated lately, which it hadn't.
Then I tried installing Speed FAN which showed that the CPU and GPU are at roughly 30 degrees Celsius and aren't really doing anything strenuous, but the fan is running at around 3700RPM. SpeedFAN couldn't find any speed controllers for the fan even though I know there must be one because the fan speed usually varies based on the CPU temperature. Because no controller is showing up there are no speed settings in Speed FAN that I could potentially use.
I've also tried looking for the fan settings in the Aptio BIOS (?) menu, but I couldn't find anything resembling them. Apparently they should be in the power menu, but it doesn't show up as a tab.
Any help would be much appreciated.
