I am looking for a quiet LOW PROFILE GPU/VGA heatsink. What would you recommend? I have a geforce 9500GT that technically only takes up ONE expansion port. However, the heatsink on it seems to barely be too big and "sort of" covers the expansion port directly below it. The item I want to put in the port below it will not fit but literally a 5-10mm clearance. So are there standards in terms of aftermarket gpu heatsinks because I would like to get a low profile/slim one heatsink for the GPU that is fairly quiet.
