I'm thinking about buying a ZALMAN VF700-CU but I heard that the ramsinks that come with it are no good. After doing some reading, the SWIFTECH MC14 ramsinks seem to have a lot of positive comments. Should I go and buy a Zalman VGA fan without ramsinks and buy the Swiftech ramsinks, or are the ones that come with the VF700-CU good enough?
