cpu fan connector help please

[dad]

Hi

New computer build

I have an ABIT kn9s MB and Im trying to connect the AMD 3 pin cpu heatsink/fan female connector to the MB The cpu fan connector on MB unfortunatly is a 4 pin connector there is a 3 pin system fan connector next to it Should I connect to the sys fan or use the 4 pin cpu connector leaving the ground pin

Thanks

Most new MB's have this connector (My M2N-E has the same). There is probably a plastic piece on that connector that will guide the pins into the right holes. If that doesn't work, you can use the other connectors on the MB if you want.

use the 4 pin cpu header but USE THE GROUND PIN its the one on the other side that is pwm fan speed control that you dont want to use.

This is fine btw, intel shows you how.
