I just built my system a couple days ago and used a Corsair H100. You are supposed to plug the two cpu fans into the H100 controller, but I would get a bios error that the cpu fans were not detected, so I plugged them into the motherboard. They ran at full speed and sounded like jet engines. Then I figured out that I can go into the bios and "ignore" the cpu fans, then plug them back into the H100 controller (which has a fan / pump speed selector button). Now it is totally quiet.
