do the fans need to be the same for push/pull?

post #1 of 5
Thread Starter 
i gutted an old dell PSU and the fan was a 92MM but it pushes about 1.3 times the CFM of my original CPU fan will it effect the performance of push pull?

and if so is there a work around?

I believe temps are better if they're the same fans. Shouldn't hurt adding another fan tho, go for it.

If it's only a 30% difference, it's not a problem. Unless it's at a point where one fan is completely redundant, you should still get some benefit from push/pull.
