I just got my gigabyte 6600gt, and before i even threw it in, i sticked ZALMAN VGA COOLER VF700-CU on it. the card is overclocked to 580/1200 the idle tempreature is 30 and only 37 at full load. i was wondering how much more should I cranck it to. btw i know the temp cause I have a temp gauge and display on my case.
