I picked up a cheap Gainward GTX275 recently and the noise of the fans on the GTX 275 is driving me crazy ever since I installed it so I've been looking at full-cover blocks to stick it into my loop, but the Gainward G200 cards use a non-reference PCB layout which only the EK 'GW' series of full-cover blocks seem to fit properly. My previous card was a GTS512 and I cooled that with an MCW60 + a D-Tek Unisink (modded to fit). I can't justify paying €85 for a block that only fits a card with a limited lifetime (DX11 around the corner and all that), plus I'd like to re-use the MCW60 since I already have it. There are no uni-sink style heatsinks on the market that I can find for the GTX275 for passive/air cooling of the RAM, VRMs, etc while leaving the GPU to a waterblock. The design of the Gainward's stock HSF is interesting, though: Fans + Shroud removed: Copper Base, Heatpipes & Fins removed: It practically has its own UniSink assembly already attached! VRMs, NVIO, RAM, the lot! There's also a 'warranty void if removed' sticker on the backplate of the HSF but who cares about that? (Famous last words..) My MCW60 is the G80 revision so I don't have the G200 adapter plate for it. I've ordered one from a dodgy-looking ebay shop for a tenner, but if that never shows up I'll just make my own and take this ghetto cooling solution that bit further. I'm not certain that the MCW60 will fit onto the core with that aluminium heatsink in place, but a bit of filing and grinding should make it fit. The other concern is that without the fans there will be considerably less airflow going over that aluminium heatsink and it doesn't seem to be particularly thick nor blessed with huge surface area. On the other hand, the two 120mm intake fans in the front of my case are blowing straight onto the card and the three 120mm exhaust fans on the bottom of the case are sucking warm air straight off the surface of the card, so I might be okay on that front. Has anyone else seen this done with the gainward/palit HSF before? Just waiting to see if that GT200 adapter plate arrives, I'll post pics and results when I try it out.
