i have 4 fan three of them intake air and 1 outtake the air from my computer

the way they are setup is in front and on the left side take in the in the back take in also but my power supply fan spits out the air

so i was wandering if i should change it so i have 2 take and 2 out

what kidn of computer do you have? is it an oem build? wht case/power supply do you have. what kind of hardware is contained therein? it's things like these that have to be considered before messing with the cooling setup.

I suppose the sizes are the same.

The back should be an exhaust.

And you didn't mention the 4th fan.

Also, before messing with anything, check if it voids your warranty. OEM builds might not honour the warranty...

my computer stuff is on my profile

the 4th fan is the power supply fan and i build this computer the only warrenty is if the parts are broken

alright, it's your build so do anything you want. experiment with different fan arrangements as you please. but if it's working now, why change it?
