After I updated to Crimson 16.1 my PSU's fan started to make loud grinding noise. It keeps doing that once or twice a day.
But after I rolled back to 15.12 the problem seemed to disappear! I wonder if it's possible that a graphics driver can even affect a PSU's fan.
I noticed that after I watched some videos (Youtube/Bluray) the problem seemed more likely to happen.
I opened the case to make sure that the noise came from the PSU and at that time both CPU's and GPU's fans were turned off (35°C and 40°C respectively). I guess I'll stick with 15.12 for a while until new driver comes or at least I know how/why this problem happened.
My specs :
16 GB DDR4 2800MHz
2TB WD Green
250GB SSD Samsung 850
Sapphire R9 Fury Tri-X
CS650M Corsair 650W
Asrock Z170 Extreme 6+
