Case fans 3 pin, motherboard has 4 pin headers.

[Mark15]

Hi,

Yesterday I swapped my PC out from my old case (Zalman Z9 U3) to the Cooler Master HAF X. I got it in all fine but the case chassis fans have 3 pin connectors whereas the mobo has 4 pin headers. I'm currently using only 3 of the four fans on the case which are connected in series with molex connectors to the PSU, which I think causes them to spin slower (which I don't want), so how can I go about connecting the fans to the mobo? Also, there are only 3 chassis fan connectors on the mobo, so how could I connect the fourth fan up?

Motherboard: ASUS M5A99X EVO R2.0

Case: Cooler Master HAF X

Cheers for any help,

Mark

The 4 pin are for PWM fans in which there speed can be controlled 3 pins are fine it just means theyll run on only 1 mode. Usually full speed
