I have an Nvidia Geforce 6600 and want to cool it down. However the products I've seen require screwing a fan and/or heat sink onto the video card which I have no problem with doing. My only consern is: my card has a 4 pin power plug connected to the PSU and the cooling units that have been reviewed as worth buying would all render the jack unreachable should they be installed. I don't have the OEM manual anymore and want to know if this power jack is for the onboard fan or for the gpu? Pretty much, will the card work if I unplug the thing? I haven't attempted to fool around with it yet as I'd like to hear from people who have had experience with it and I really can't afford frying my card. Any feed back would be helpfull.
