I solved the high-speed fan problem after installing bumblebee. I followed the instruction on Antergos wiki, everything worked well after properly installing it. After certain updates, my fan run at high speed all the time again. I tried to find out what’s wrong, but the only different I found so far is that some options in nvidia x server settings are gone. Please help me to find out what’s wrong. Thx!
Edit: After reinstalling powersvaing patch and reboot for 2 or 3 times, it just fixed…Maybe I accidentally update bumblebee and lost the power saving patch.
