both then. i really hope you didnt pay for them as i generally find them to be a rip off. not much noticable increase in cooling, but they sure do seem to cost a nice littl chunk at retail. i just chop apart my horde of old heatsinks, its free
Once you fit them could you tell me if they make any diference to your cards overclocking as im not sure if its worth getting any or not. I wasnt going to bother but i now know a guy who has some going cheap.
