Fan Mount Direction

post #1 of 66
Thread Starter 
I have 4 140mm slots fans and 1 120mm slot fan.

2 - 140mm on top of case

2 - 140mm on side of case

1 - 120mm on rear of case

My question is which way should I mount them meaning how many pulling air in how many pullign air out and which ones?

What case do you have?

There are two types of air pressure: Positive and negative. Both have pros and cons to them.

One mistake he made: Positive airflow will result in less dust.

Generally, the front of the case is intake, top should be exhaust, side can be exhaust or intake, but is mostly intake.

You need to give more info on your rig. What case, GPU, water cooling or air cooling.

I built it 2 years ago . Dont rememebr what is in it anymore. I have no issues at all but was just curious. all the fans are pulling air out currently

So all of them are exhaust? If I were you, I would make the side intake just to get a little more air in.

even though the side fans will be pushign air directly on to the cpu fan few inches away from side fans? wouldnt that put strain the fan?

If clearance is an issue with it then I'd leave it. It would put strain on it. Are both of them blocked by the cooler?

No it wont put any pressure on the fan, but seriously you should change your configuration so that the front and side fans are intake and the top rear fans are exhaust. This just keeps cool air flowing from front to back and rising to be exhausted as heated air does. At the moment you've created a mild vacuum with all fans being exhaust your components have very limited cool air to use for cooling.

alrighty i will def do that then. i dont have a front fan just one that is in a 5.25 bay and taht is actually blowing out and its cold air.

Make both the top fans and the rear fan exhaust, and make the side fans intake fans. That should even things out a bit, as well as keep your CPU and GPU(s) cooler thumb.gif
