I have two 120mm fans from Corsair (The grey AIO fans) and when I plug them in on my mobo they get pretty damn loud (2600rpm) and they sound like a tiny jet engine, my mobo is a GA-78lmt-s2p and the ccase fan header is a 3 pin and my case fans are 4 pin so is my splitter, so can I change the voltage or something for my fans?
