I've been considering the fan placement in my case, as a few people probably have after the Bit-Tech article. I bought a few fans from the marketplace here, and have been debating how to best place them for cooling my system. I've obviously read a the article on this site and done a bit of research elsewhere on the internet and still can't come up with a straight forward solution as my system isn't the generic, 2 fans in, 2 fans out with an air cooler set-up. For a start, the cooler is an Antec Kuhler H620, which is doing a great job of cooling my CPU but is recommended to be used as an intake, obviously this isn't ideal. With some systems you can just run them as an exhaust without much issue but the 2nd consideration is that my graphics card uses a Twin Frozr II cooler which doesn't exhaust the air out of the case, raising the ambient temperature. Using the fan on the cooler as an exhaust would then be pulling the warm air from the graphics card through the radiator, which I don't imagine would be a good thing! So the idea I have come up with is below in the crappy diagram: The theory being the cool air from the front is drawn in, will mostly pass over the graphics card and then be drawn out of the side of the case by the fan in the side panel. The warm air from the radiator (cpu never really gets above 50c under full load) would then be extracted out of the top of the case before it gets chance to reach the rest of the components. The PSU pulls in it's own air from the bottom of the case and vents it straight out the back. I feel like I must be missing something totally obvious though as I've not seen anyone else using a similar arrangement. Any advice or alternative suggestions is greatly appreciated. FYI the other possible fan placement is a 120mm (don't think it will fit a 140mm but it might) fan in the floor of the case in front of the PSU and I might be able to squeeze a fan in the 5 1/4 bays with cable ties but I am not 100% sure, would also require me to move my dvd drive and reroute some cable tidying.
