The problem isn't personal and a lot of Ubuntu users which has no pwm control of their fan, can use this kind of workaround.
The fan of my laptop is CPU dependent, and doesn't care about Nvidia GPU's temperature, only increases speed when CPU temperature affects GPU temperature. But it's not that much ofc. I already cleaned dust and refreshed thermal paste.
I tried a lot of things with
grub settings and many of other packages which I seen on other questions. But unfortunately my system hasn't control of pwm sensors of fan.
And I use both, Intel® HD Graphics 4600 is very okay for me, for desktop usage. And I'm using nvidia gtx960m on background, with
bumblebee. But it was like this before too, when not using
What can I do as a workaround?
Clevo-W230SD laptop with intel HM87 mainboard, ubuntu 16.04 LTS installed. Just after booting, fan goes up to 100%. And doesn't go up that much again.
