i have an 8800GT 512mb card with the arctic cooling acelero s-1 mounted to it as a totally passive cooling device (no fan) and it stays no more than warm. its also a slim design for sli set ups

i have a q6600 quad core processor and use a coolermaster centurian 5 case

its quiet and everything runs cool.

as for the question, why do the fans keep crapping out?

well they are cheap light weight and overworked its just the size is so small they can only do so much to beef them up so if they push too much air for the size motor it goes bad sooner, its just the nature of size vs weight vs airflow.

try this mod if you have the room:

remove the video card to your desk.

remove the cover plate over your fan and heatsink but do not seperate the heatsink from your video card. (be carefull the screws can be very small)

now install a case fan (usually 60mm or 70mm size) as big or slightly bigger than the hole size on the outside of the coverplate and mark where the screws go to drill screw holes. mount the fan so it will blow air into the card and mount with flush mounting screws, preferably the ones that came with the fan. reinstall the coverplate and test to be sure the stock fan blades still spin freely. for power you will plug the 4pin fan plug directly into your wiring harness. now replace the cover plate but first make sure the old fan is unplugged but you may need to tuck the plug and wire out of the way, even if it still works you do not want to have both running at the same time, it screws up the airflow.

the way this works is the case fan blows a lot more air into the card than that puny flat piece of crap stock fan and the stock fan you left in place will spin as the air goes by causing it to rotate backwards and direct airflow as needed accross the entire heatsink. i tried this without leaving the old fan in place but it cools better with it, it helps the air change direction from vertical to horizontal i think.

now if for some reason yours doesnt cool well try flipping the case fan over and reversing the airflow direction
