Cooler Master HAF 912 stock fans' airflow?

[OWEN10578]

I'm planning on a new rig as some of you know, and I plan to use a Cooler Master HAF 912 Combat case. The case comes with 2 Cooler Master Silent Fan SL1 fan that spin at 1200 rpm; now I want to know how much air it pushes, on Cooler Master's website it says 44cfm but we all know manufacturer's specs are most of the time inflated. So if anyone of you have this fan, does it push a lot of air? And if you can estimate it's cfm. I want to know this because I want to make a negative pressure case so I need the stock fan info to buy the right cfm fan for the rest of the mounting holes.

If you want negative internal air pressure, then set the front intake to exhaust.

i have a HAF 912 with 3 fans 2 200mm and 1 120mm i think.

im curious how u set a fan to exhaust so it extracts air from inside.

will this also help with dust build up?

The hell? Then where would air come from? What kind of advice is that?

To set a fan to exhaust, just point the fan's side with the spokes to the vent of the case, then it will exhaust air outside. A positive air pressure is better for reducing dust buildup. And please can you tell me if the HAF 912's stock fans are powerful?

From anywhere else. There are other holes in your case. If you only push air out and do not push air in, then air will naturally come in from any opening to replace the air that went out to maintain equilibrium.

Then the case will have ridicuously low, undirected and stupid airflow.

But you wanted negative internal air pressure. I am only respecting what you want. In general, negative internal air pressure does not go hand-in-hand with good airflow.

not trying to hijack but curious how you set a fan to exhaust?? i would like to set 1 fan to exhaust to faster cool the inside. will this be an issue as the front fan is set on a 3 pin pwr fan slot

I know, but when i said i want negative pressure it's not like that. I meant that the exhaust is higher cfm than the intake.

Just flip the fan...

@peter12: please start your own thread.

@OWEN10578: Yes; you are correct. It really comes down to what your build is and if you need higher CFM fans.

Yes, you understand thank you. So, do you have a haf 912?

I have the Cooler Master HAF 912+.

I have the Cooler Master HAF 912+.

IS it a good case? Does it have good cable management? Does it have good airflow? Cause I found a case called Bitfenix Shinobi for cheaper than the HAF 912 and the Shinobi looks better to me. Is there any extra features to still justify buying the HAF 912?

Yes. Yes. Yes. And go with what you like. You are the one who has to work and look at the case. I would recommend the HAF 912 for its better quality build and better airflow design.
