Best Airflow Configuration?

post #1 of 31
Thread Starter 
I've been reading through the forms, and apparently pressure can build up in your case(?) Not exactly sure; but thought I'd check up on it.

My question is, what is the best fan configuration for my case? It has three total fans, one in the back, side panel, and one in-front of the HDD cage.

If you need the exact fans I am using, I can provide that information.

Also, my case is in my 'sig'; if you need pictures of the case just go on Newegg.com/Amazon.com.

Best config with 3 fans is pretty straight forward. You want to create pass through airflow. One fan intake and one fan exhaust front to back. It doesn't really matter which direction. The side panel fan is usual lined up on the video cards. I don't know about that case for sure, but typically folks tend to blow air on to the video cards so intake again.

As far as pressure, you can creat negative or positive pressure inside a case depending on how much air you are pushing via intake or exhaust. Personally, I prefer positive pressure - more intake fans than exhaust fans. The reason is the air will find a way to escape through any cracks or holes in the case. The positive pressure will keep pet hair and dust out of the case.

Problem with doing the front fan intake, and back out, is that the front fan in-front of the HDD's is probably not getting very much air in.

(Can see in the attached picture)

Currently I have all fans blowing in.

I would have all the fans exhausting and remove any filters on the fans.

Stock at the moment; but planning to use either the h80 water cooler, or hyper 212.
post #9 of 31
With the H80 cooler you will want to Probably add a top mounted exhaust hole as it performs best as an intake cooler
post #10 of 31
Use the front as intake and have the side fan as intake and the rear fan as an exhaust,

Because the front fan will lose some of its airflow due to restriction of the HDD's then the side fan will compensate for the fronts short fall,
