Fans! Push or pull? Easy quick question!

post #1 of 24
Thread Starter 
I have a few fans around my case. I have the one on the back which exhausts the air, I have one on top which seems like its exhausting aswell. And the one on the side I cant tell if its pushing air our or sucking it in. Its the only fan on my case that I purchased separately. I have the HAF 922 and I added the fan on the left hand side. Should that fan be pushing air IN or blowing it OUT?

Please help me it kinda seems like its sucking air in

I would use it as an intake, it will help your gpu get fresh air.

Ya I feel like if that big 200MM fan was blowing air in that would be hitting like every component keeping it nice and cool in there. Then the other two case fans are exhausting.

You've got a 2500k clocked to 4.8GHz and you're using the 212+. The 212+ is pushing the air at the side of the case off your CPU, if your side fan is an exhaust fan you're gonna get more air out of the case.

Also, pushing air into the case from a side fan interrupts the airflow from your front fans to your back fans, leaving more air in the case.

Edit: I may be wrong though, with your 922 it could be different. Test the two out and see which one works best for you.

I don't get how the hyper 212+ is pushing the air to the side. Its pushing from front to back

so it pushes right back to the exhaust. that seems fine. the fresh air in from the side will help with gpu temps.
