Comment 7 for bug 1602888

I've noticed that without the nvidia driver installed the GPU temp sensor always reads 1c. After the nvidia driver is installed it reports the correct temp. I think probably not related to the fan issue. Also it seems strange that the fans stopping didn't survive a reboot. I've noticed that if the laptop is cool sometimes the fans will stop on their own. But this happens very very rarely, and only if the ambient temp is cool as well.

The best explanation/theory I've heard for the fan issue is #14 on this thread:

In any case I think this bug needs to be reported upstream to the Linux kernel team. I'm not sure where or to which maintainer though. I've had to resort to using Windows 10 with cygwin (Yuck) and unfortunately had to remove Ubuntu to free up drive space :(
