hi i currently have a cooler master haf 912 case with 3 case fans. 1 in the front, 1 in the rear, and 1 on the top. How much will 2 or 3 additional case fans ( 1 in front, 1 on top, mayb 1 on the side) help my hardware? how many degrees celcius drop can i reasonably expect?

thanks! :hello: 

edit: oh yea, its all 120mm fans 2000 rpm

Well, depending on the size of the fans, and also if its a pull/push exhaust configuration, you may be able to reduce anywhere from 0c-5c.

bit of a subjective question really

since we dont know what hardware you have in there

and if its already running cool enough

its kind of hard to answer

It really depends on what your hardware is and what you do. More fans doesn't always mean better temps, but it always guarantees more noise.

If you have a power house inside (SB-E, 590), you might notice a difference in temps. If you have a i3 and a low end GPU, you most likely benefit from extra fans since the 912 is already a great performer at stock.

we don't know your hardware and how much your present temp, but i think these 3 fans is enough.. 1 in front for intake, 1 at the rear for exhaust and another at the top also for exhaust. But put in mind that your intake must be equal to exhaust. Push and Pull..

Fans work best with positive pressure flow
more exhaust than intake
for an example look at the corsair 600t
1 200 mm intake
1 200 mm and a 120 mm exhaust
