Replacing PSU fan with a 4 pin variant

Hi All,

My PSU fan is now the loudest part of my system so I bought an Akasa APACHE fan to replace it. the problem is it has a 4 pin connector and the PSU only has GND, 12v. I have connected the Ground and 12v wires together and booted. It will only pulse the fan though and wont spin up. Can anyone help??

Thanks

  1. Which pins on the did you use? I think the correct pins on the fan are the ground pin and the wire right beside it.
  2. I've tried all four

    PSU has;

    Red
    Black

    Fan has;

    Black
    Yellow
    Green
    Blue

    The pulsing occurs when the blacks are connected and the red is connected to the yellow??
  3. OK. I think I see your problem. You want to connect the fan's yellow and black wires to the PSU's yellow (12 volt line) and black wires. Use a drive molex.
  4. I cut the old fan off which was connected with a red and black wire. There is no yellow wire connected to the old fan. Do you mean to splice into a yellow wire exiting the PSU?
  5. Just tried it in a molex connector, black to black (GND) yellow to yellow (5v) works. Now how to sort it in the PSU ??? Hmmmmm
