AirFlow

I have decided I am going to change my case as I have grown bored of the bit ott of my Antec 1200. So I will be switching to a Corsair 800D. I will be getting all new fans as well as I understand the stock ones are not great. My question is this.

I was thinking of only having the rear fan as the exhaust and having the bottom one as intake as it set but then putting 2 120mm in the roof and having them pull air in. My system is an air cooled system and my research has told me that the 800d is not great for air flow but as said will be changing out the stock fans. Would this set up on the fans work??

Do you mean having the top two suck the hot air out? If so yes. Thats how i have my 912+ setup with a 200mm exhuast fan on top sucking out the hot air from my nh-u12p se2.

Generally, Bottom and Front are intake, Top and Back exhaust.

You could just try and see, I did try this approach while I was on air (albeit with a poorer case). Blowing down onto the HSF raised temps by 3-4c for me, exhausting via the top, assisting what happens naturally (hot air rising) makes more sense, especially as they would be sucking hot air from the HSF rather than blowing ambient air onto it.

In theory it could work however, provided your heatsink fan can pull allot of air.

Or how about reversing the rear exsaust and have that as an intake then exsaust out the top of the case. But I would reverse the flow of my fans on my cpu cooler so they would pull air from back to front.
