hi guys i got 2 cheap case fans .these fans have 4 wires coming out of them but only 2 are connected to the molex header(red and black).remaining two wires are left without connecting(yellow and blue).i connected the 2-pin molex to my psu.and the fans run at full speed always.they make a loud noise always.Am i right in saying that i can connect the wires to a 4-pin pwm header thereby able to control the speed of the fans??.
if so can i connect the 2 fans to a single mobo-header.my motherboard is gigabyte ga-h81ms2ph.
