Windows 7: 4-pin Fan Splitter

hArLtRoN · 25 Jul 2012

I am going to upgrade the fans on my CPU cooler with 4-pin fans so I can take advantage of the 4-pin connector on my motherboard.

The cooler has mounts for (2) fans. All I am finding is 3-pin splitters, like this one, but not a 4-pin splitter.

Thanks for any help!

Noctua NF-F12's come with the pwm splitters. I just happened to order two fans but I think I'm only going to need 1 splitter, and if that's the case, I can send it over to you if you'd like.

Could you provide me with a link to where you bought yours?

I might take you up on your offer

I got them off of Amazon. They were used for $11 and said it only came with the fan but no box or accessories but when I got it it came with everything including the box.

You need to determine if your MB can support the power of two fans from that single header. If not, you will want something like below, which gets the power from a PSU Molex connector but the signals from the two fans.

Newegg.com - Rosewill Model RCW-FPS-401 12" PWM Splitter

Otherwise if the motherboard connector can supply enough amps for two PWM fans:

I'm going to go with the Rosewill adapter because it will work with the motherboard I have now and the new one I will be getting in a few months.

Thank you all for links and help!
