Push/Pull Question

post #1 of 4
Thread Starter 
I'm in the process of planning a new MM U2-UFO build and I had a question about push/pull fans on two RX360's on the front of the case. What would be the effect of using two different RPM fans? I would be using push Xigmatek XLF 1500 RPM, and pull 2150 RPM gentle typhoons fans attached to a fan controller that I would adjust as needed by temps. Would there be an adverse effect having this layout?

As long as you can semi-match the fan CFM (not always speed), you'll be fine. Problem with different CFM, you will put extra stress on the fans.

I tried this once in my U2-UFO with two different fan speeds on each side and all I noticed was noise increase...Temps moved maybe a degree but nothing more...I suspect it was because my rad likes lower speed rpm's for its max heat dissipation and my higher rpm fan really wouldn't help the cause.

By that theory I should be OK then. According to the Egg, the Xigmatek's have 61 CFM and the 2150 GT's are 69 CFM. Thanks for your help +rep
