Is it 4-pin connector (molex) have 2-wires & fan like connector only 1 wire?
if that so; 4-pin molex provide full 12V power from PSU, so full speed according to it's spec. Fan connector-like provide speed reading only. You have to mod the 4-pin either convert to 7V/5V (fixed speed) or change to 3p/4p fan connector & connect to your fan controller for control the speed. |

You can control the speed thru motherboard, provide that your motherboard have the 4-pin fan header. This post has been edited by kherel77: Apr 11 2017, 05:08 PM |
