I can't find an adapter, if you've already ordered it, just try anyways by plugging in only some of the pins. What's the motherboard?
^You won't need an adapter for it. It will just fit. The 4th pin is for PWM.
Oh, didn't know that!
I have a The MSI MS-7548 (Aspen) motherboard and the stock fan I currently have is loud. And I'm forced to run the PC on power saver, it's loud on balanced and high performance power setting. Will this fix the problem?
