Fans running full speed on skylake platform

[Sebastian Heiden]

The Fans on my ASUS GL502VT Laptop start spinning full speed after about 2 minutes after bootup in default mode. If I boot with nomodeset boot parameter it seems not to happen. The Device is running the lastest BIOS by ASUS.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

As this is a brand new device I tried 16.04 LTS first where the bug was persistent, same for 14.04. But the lastest upstream kernel fixed this. Thanks for your help.

I tried 4.7 mainline and 4.8 mainline and still one of two fans in my laptop run at 100%. (I have Clevo with Skylake desktop CPU).

[Sebastian Heiden (seb-heiden)]

Maybe its a dedicated GPU Fan Controlled by the GPU? Try installing the lastest Nvidia Drivers, use mainline 4.6 for that and the Nvidia Drivers ppa.

[Magnes (magnesus2)]

Yes, it might be the GPU fan - since it's on the right side of the laptop (the fan on the left seems to be controlled just fine), latest Nvidia Drivers don't help though. It's likely a different bug then, I will try reporting it to nvidia instead.
