2 80mm exaust question

[sifu quoc]

does anyone really see a significant change in case temp with these there???

i have a full tower with a 120 mm @ 7v intake and was replacing my ps fan to be stronger... so would i really need those 2 80 mm exausts? i'd never feel any warm air leave them anyways....

What you want to do is equal the intake with the exaust...So, depending on the cfm's the intake is blowing in the 2 80mm exaust and the PSU may equal out, so you may not need to replace the PSU fan...

my 120 mm intake is 131 cfm at 12 v... so at 7v does that equal 76 cfm?

It's a good approximation...
