Default Fractal R3 side fan in or out

Hi guys I recently purchased a Fractal R3 case and its setup with the supplied Fractal fans in the front for intake, one Noctua 120mm on top for extraction, my ECO cooler extracts out of the rear. I need to know whether to have my 2nd Noctua fan mounted on the side blow air in or extract it. I have 2x 5850's in Xfire so was thinking extract their hot air out?

I would blow in if the cards are external exhaust, if not take air out.

YouTube - Fortress FT01 PC case with positive air pressure part 2

I have had the fan blowing out since I posted and temps are not too bad, but I might switch it up and see what happens.

I didn't put a side fan on because you should get sufficient airflow if you have a couple good fans at the front.

Its not filtered... exhaust or block it off, do not use it as an intake unless you add a filter...

positive pressure (i.e. more fans sucking than blowing) is great, HOWEVER unless you have filters it will create a dust nightmare in your case (I learned this with my experiences with the antec 900).

Well I am using the fractal fans at the front for intakes and then two noctua 120mm fans, one on top and one on the side both exhausting air. The rear is taken up with my eco alc cooler.

Yeah I would also go with exhausting on the mounts without filters.. I have the same case right now, based on my experience with Antec 900's and Coolermaster HAF 922 intaking air without filters is horrible :P
