Power cables for case fans

[Adamczyk]

I'm getting a couple case fans but am a bit confused about how to power them.

These 2 cables are confusing me:

Akasa 3-Pin to 4-Pin Adapter Cable
Akasa AK-CB423-ADPT 4 - 3pin adapter cable

I never done this before but I assume I need to convert some 4 pin molexes to 3-pins. So in theory I need a cable that has a 4-pin female on one end and a 3-pin female on the other.

So which one do I need....?

Akasa 3-Pin to 4-Pin Adapter Cable: Judging from the title it seems like it's not what I need, but if you look at the image, it has a 4 pin female and a 3 pin female and another 3 pin male, so that's what I assume I need.

Akasa AK-CB423-ADPT 4 - 3pin adapter cable: Judging from the title, this seems like the one, but as you can see in the image it has a 4-pin male and female and a 3 pin male so nowhere to plug-in the fan.

Please someone get me out of this missery!!

P.S. These are the fans I'm going for, I you got any suggestions for better ones, don't be shy

O, and this I my PC's blueprint so far if that helps...

motherboard should have 3pin headers that you can plug the fans straight into and power them off

I was thinking that and had a better look. I can spot 3. In the spec they don't seem to mention 3-pin's though but load of "headers"....

Sorry, this is the right pic.

I think 2 of these will do the job actually.

Just plug them into the mobo

if you have more fans than headers then you can get 3 pin spliters to run 2 fans off 1 header... just make sure you check the amps/watts of the header vs the fans
