You are correct to note that the cooling design of your MSI GTX580 Twin Frozr II is a bi-directional design. It dumps half of its heat into the case via the card's front. The front VGA duct of the HAF-X will not help but will make worse
the situation as it forces hot exhausted air back into the cards. For the same reason, front lower case fan should not intake air with high velocity.
IMHO, you need to make 2 provisions
a clear and distinct escape path for that internally dumped hot exhausted air, making sure these air do not
go through the rad of the H50. (Solution suggested: a 'top exhaust' approach)
an extra supply of fresh ambient air to the 2 cards (especially the top card), particularly having more air getting into the gap between the 2 cards. (Solution: strong side panel 120mm fans)
Let me demonstrate these 2 using HAF 932 (which I am familiar with) as an example: (See pic below)
--H50 installed with its rad-fan at top rear position
--two 120mm fans installed at other top 2 positions
--main case intake fans are four 120mm fans at side panel. They supply ample fresh air (blue arrows in pic) to both cards and to the upper portion of case to go through H50 rad-fan (These 4 fans should be speed adjustable to achieve noise-performance balance at will)
--cards' front hot exhausted air will be sucked upward by the 2 top front fans
--case front lower 230mm fan spin slow and will cool (front blue arrows in pic) the HDDs. The warm air will follow the upward draft to the top
--install a slow spinning fan at case rear top for exhaust. Its function is to prevent any warm air (exhausted out of the case by the 2 cards and the PSU) to be 'drafted' into the case through the opening. It should not spin fast, or else it will compete for air with the 3 top fans.Edited by windfire - 4/13/11 at 11:56pm
