so for some reason when I play games on my pc the fans ramp up every 3-4 mins for 15 - 20 seconds, and when I mean ramp up they go to FULL speed. Ive changed fan curves and I’ve found out it’s my fans that are on my fan hub. they are all set to reSponding to the cpu temp. unfortunatel, my fan hub had to plug into the cpu fan header, and the cpu cooler into the sys fan header, but as they are set to cpu. also in bios when I change it to pwm it does the exact same thing. pleas help.
