positive air pressure

[Ghostypoo]

would like to set up a positive air pressure in my new case 570x. ive ordered 3 corsair 120mm ML fans for front intake and attaching a corsair H100i V2 right behind it, for the rear exhaust i also ordered a 120mm ML fan, now for the top is where im not to sure about, i ordered 2 140mm ML fans to set them as exhaust. should i have ordered 2 120mm ML fans instead? or do i just find a way to make the 140 fans spin slower and the front faster but still somewhat silent?

this is my 1st time installing an AIO so the fans attached to it automatically runs faster? and if i did make the rear fan exhaust it wouldnt make my case run hotter right?

I believe ML fans are PWM, i.e. 4-pin speed controllable.

 

You've got a lot of fans to control :). I would replace the aio fans with two of the front ML. These fans could be controlled by the aio to optimize cpu cooling. Depending on your motherboard, there may be an aio/cpu fan header that could be used instead.

 

Again, depending on your motherboard you should be able to use its fan headers and fan control software to optimize airflow.

thanks, i have the asus viii hero, havent played much with the utilites aside from the gpu tweak. stiill gota do some reasearch on how to properly optamize the fan speeds for my situation

Excellent motherboard with 6 PWM capable fan headers. Plus a header for an aio pump. If memory serves, the Fan Xpert software allows one to set fan profiles for each fan based on nearby temperature sensor values.
