How much cooling performance will I gain or lose between these two cpu fan configurations?

[doubledogdare610]

So I have a Cm Hyper 212 evo. And I'm trying to figure out if I will gain or lose cooling performance between the stock fan on my cooler and two new Cosair fans. Here I will add specs of these fans:

Stock Fan:
82.9 CFM
2.7 mm H2O (Static Pressure)
2,000 RPM (PWM)

Two Corsair fans:
62.74 CFM
3.1 mm H20 (Static Pressure)
2350 RPM (PWM)

Any and all help will be appreciated!

it might lower temps by a few degrees, people usually change the fans if they are changing all the case fans aswell to make it match.

I think you'd definitely get a difference in pc cooling if u changed everyfan from stock but it wont be much
