Hi,

I recently bought 2 fans (Cosair 4Pin) - [ Register or Signin to view external links. ]

The guy at the store told me I didn't need any cables and that everything I needed came with them.

Yet when I opened up my PC, I couldn't find anywhere on my motherboard or PSU to connect them two?

I have this motherboard: GA-H81M-D2V - [ Register or Signin to view external links. ]

If anyone could help it would be much appreciated.

I currently have two fans installed, Both of these I think are installed on my motherboard.

Thanks!

Your motherboard only has two fan headers, the CPU_FAN should be connected to the fan on your CPU cooler (depending on which one you have), and there is only one SYS_FAN header which will be connected to a case fan. I'm not sure how you have two fans but only one header but whatever. To connect your new fans, you would need a molex-to-3 pin adapter;

Alternatively you could get a 3pin splitter that creates multiple male connectors from one female one, but it can get a bit bulky if your case doesn't have much cable management room;

Thanks, just what I was after... Will order the 4-Pin Molex to 4 x 3-Pin cable.

And as for the fans in my PC itself, I have one at the front and then one at the back?

Not really sure what you're on about with header etc...

Fan headers are the connectors on your motherboard. I was confused as you say you have two case fans, but only two fan headers on your motherboard, one of which is for your CPU cooler.

One of the fans goes straight to my PSU... I checked it last-night when fitting the new fans.
