I'm contemplating a smallish-footprint mATX gaming build using the Silverstone FT03 case. The whole cooling scheme for the case is based on stack cooling, and my intent was to have an entirely air cooled system, with fans cheerfully ushering warm air up and out the top of the machine with the help of basic physics.
The question is the choice of GPU - or specifically, the choice of GPU cooling system. I'm likely running a single GTX 770 card, and I'm trying to decide which form factor to use. In standard cases, the ASUS DirectCU II system will result in a cooler running card. My concern is that since it doesn't purely blow air up and out of the card ala the reference blower system, it'll result in overall higher temperatures as it essentially pipes warm air and turbulence into the stack. But I have no idea how big of a deal this is, and if it'll be offset by the better cooling properties of the DirectCU II card in other ways.
Thoughts?
