Hi I have a annoying issue with my CPU fan I have it set to Target 65 Celsius and Level 1 fan speed this has been done in the BIOS however when my CPU reaches around about 50 Celsius the fan speed will go from 2000RPM to 4000RPM and it will keep increasing and sound like a jet on takeoff. Surely it should not speed up till it reaches around the 65C area. Is there another setting I have missed?
Any help would be greatly appreciated.
