    You talking about hooking a 3 pin CPU fan to a 4 pin motherboard CPU fan connector? If so using a 4 pin adaptor is a waste of time. The CPU only has 3 wires regardless if you use a 4 pin adaptor or not. Motherboards 4 pin CPU headers are keyed so you can plug the 3 pin into it.

    No. The CPU fan has 4wires (so it's pwm), but the connection on my fan controller is only 3 pin. So I need an adapter for it.

    Why is that? I think it would work.

    It has a molex on it. He needs a 4 pin PWM to 3 pin adaptor.

    I thought 4 pin was molex, nevermind.

    The molex one listed earlier would still work for you though, right? It's not like you don't have an extra molex connector open. Unless, though, you want to control fan speed, in which case you would need the other kind of adapter.

    No, he doesn't want to power the fan. He wants to hook it up to his fan controller that only accepts 3-pin plugs.

    Oh, I see now. Just try to do some searches on ebay. You'll find something eventually.

    It isn't exactly what you asked for, but does the job fine:

    http://www.scan.co.uk/Products/Akas...nnectoer-for-RPM-feedback-for-the-motherboard

    You plug it into a molex adapter from the power supply, plug one into your motherboard (the only female one :p) for fan control and then you have 3 of the 4 pin connectors that you need, so enough to plug into your motherboard and keep a spare if you have to unplug a currently being used fan.

    Scan are in UK too, so shipping should be cheap (they send by courier though, so don't quote me). If you are in north west UK, they are based in Bolton, so you may find it cheaper to go pick it up yourself (on the retail park opposite Reebok Stadium)
