Suddenly my fans are spinning at 100%. The device woke up from sleep and started cranking and GPU temperature is at 41 deg CPU at 1% usage. How do I stop it? How do I fix it?

Hi there,
It is possible that the fan would speed up after sleep mode, as it is re-detecting the temperature and settings.
but it should clam down and stabilize after a while.
May you specify more if you still have the issue?
Thank you.

@potatosubwoofer, mine behaves the same way, after sleep or hibernation.
I have other machines, from Toshiba and Lenovo, that behave the same way. Even my macbook pro does it, from time to time, specially when docked to a hub. All of them, after a while decrease fan speed and work as supposed to.

I meant more like it was spinning at full for a few hours for no reason. I left it to see if it would go away on it's own but it didn't.
I did figure it was a sleep state problem and I managed to make it stop by shutting it down on battery, plugging it in and then turning it on while plugged in (or some combination of such). Very strange, as I certainly wouldn't want this to happen while I was away from my charger (and for that matter it really shouldn't happen at all)

Ok, that kind of behaviour I've never witnessed. Can it be some software it the background that controls the fan, like a temperature monitor or something else you have installed?
