Air filter on the top exhaust ports in my case affecting air flow.

post #1 of 5
Thread Starter 
I just got a Fractal Design Arc Midi R2 and it has a air filter for the exhaust ports on the top of the case. From what I can tell all this does is restrict airflow going threw my top radiator.

I'm wondering If there is any reason to have this air filter or should I just leave it off?

The filter is likely there so that if you chose to flip the flow and have the top as intake, you'd be able to filter it.

If you are leaving it as exhaust, you might as well remove the filter thumb.gif

Thanks, I was so confused when I saw the air filter.

Why would anyone want to use the top as a intake?

From my experience, any air filter or grille adjacent to a case fan will reduce air flow and increase noise. Unless your blowing smoke into your case take it off. Also, why is there a filter for an exhaust?

By top do you mean the roof of the case?

I used to have an H100 mounted to intake from the top. I know it doesn't make sense, and it goes against the natural path of air, but it gave me better temperatures.

The filters can be useful if you wish for your case to build up dust inside - it's easier to clean the filters than it is to clean the inside of your case + components.

However you do take a slight performance hit in terms of air flow being restricted.

Alternatively, maintain positive pressure to reduce dust build up.

Currently, I have filters on the fans on both of my radiators, it is so much easier cleaning the filters than removing fans and cleaning them + radiators.
