  1. I have an ASUS P8B75-MLE Micro ATX motherboard, it only has 1 chassis fan header. My case (HAF 922) as 3 fans. My PSU is an OCZ ZT Series 650W.

    What kind of adapters do I need to connect them all up?

    Hi alexjsc, One way to power extra fans is to tap off 12v from one of your 4 pin molex connections, to, say a DVD drive.
    There are molex adapters which have a plug on one side and a socket on the other, plus a small plug for one of your extra fans.
    You need to check the number of pins on your fans connections, could be 3 or 4, but you need power for 3 fans also.
    Also, do you want to be able to slow the new case fans, or to have them running full speed always.
    This is the type of connector;
