Case Airflow (Which is best)

Twirlywoos · 18 Sep 2012 at 16:29

I'm getting a couple of 670 Windforce X3's soon and would like your opinion on which airflow would be best for my setup. The WF exhausts into the case and not out the back like conventional cards.

1) The Red = Exhaust done by a 200mm Spectre Pro I have on my side Mesh. Plus two AP15's at the top will be intakes.

2) The Blue = Intake done by a 200mm Spectre Pro I have on my side Mesh. Plus two AP15's at the top will be exhausts.

3) Or would you suggest something else?

Thanks

option 2 but with the CPU rad on intake rather than exhaust

+ psu face down if that case has a psu intake filter at the bottom

Option 2 with psu down as C64 says are those 2 roof exhausts? How far forward are they? Do you have 3 fan bays in roof? Use the rear 2 If so so ou don't disrupt front intake

I have a similar set up and I was advised that the CPU rad should be an intake - pulling cold / fresh air over the rad from outside and then I exhaust through the top using rising hot air (helped by a 140mm low rpm fan).

I also have my PSU the other way up so that is pulling cold air in through the bottom of the case (through a filter - Antec 302 case) and exhaust at the back.

I prefer having the CPU rad blowing out the case. This reduces the build up of dust in the rad.

I tried both options and 2 is definitely better having cool air blow over the cards. I've seen a temp diff of 14 degrees on both cards. I've ordered a filter to have the cpu cooler intake air from outside and I'll turn the psu around this week and report back.

I would have imagined having the mesh fan acting as an exhaust would have been better but low and behold I was wrong, but Thanks for your suggestions.
