Hi I've just completed my htpc. I used a ps3 case to put it in due to hight issues I used a single fan to cool it all. I used a fan from the ps3 this is a great fan that shifts a lot of air my only prob is the sound. My question is is ther a way to slow it down a bit so it's not as loud?. I know it's a pwm fan that uses a 3rd wire to adjust the speed. I Tryed hooking it up to a pc psu and sueing the 5v line to adjust the speed but it still spins at the same speed.
