H100 Fans perma full speed.


Recommended Posts

Hello Guys,


I have had the H100 working fine for months now except for the grinding noise. I unplugged the two fans from the top of the pump, and once I have plugged them back in the fans stay at full speed.


I have tried resetting the pump. Turning off CPU fan control in the bios but nothing seems to work!


They are really loud, it sounds like a plane taking off!!


Any suggestions?

Try resetting the unit and see if that changes;


To reset the firmware, use the following procedure:

1. While the computer is running, hold down the profile button for approximately five seconds

2. Wait one minute, while the unit continues to run

3. Shut down your computer

4. Press and hold the profile button for five seconds while turning on the power to your computer.
