Fan SHIM uses a friction-fit header so it can be pushed into place. If you can, I'd just leave the CPU fan header unplugged and power the replacement fan off of a system fan header or 3-pin molex to 3-pin adapter. The fan stays on permanently and has a functional tacho output. It will typically just run at 100%. FREE Shipping on orders over $25 shipped by Amazon. Comments. I have never seen a case/CPU fan with +12vdc on pin 1. In a 3-wire fan, first two wires are the power supply wires of the fan. Name * Email * Website. a 3 pin fan is going to have a ground pin, a 12v pin, and a sensor pin. Pin 1 is always ground. A 4 pin PWM (pulse width modulation) fan will have the same 3 pins plus a 4 control pin. Learn how to configure the speed of any fan located inside your PC (CPU, VGA, chipset, case, etc.) A musician friend of me with no money just got an old PC Core 2 Duo with two 3 pin fan headers and a very noisy ~3300 RPM 4 pin CPU fan, so you guess it runs at full speed. 3 pins will not work on 6 pins since they are … The tacho signal from the fan sinks to ground for every revolution, the input on the motherboard is pulled high.
