The GTX285 heatsink is designed to cool surface mount components (memory, voltage mosfets, I/O chip) on nVidia's reference design GeForce® GTX285 graphics cards. It is designed to be installed in conjunction with our MCW60 VGA water-block and allows the highest possible stable overclocks of these high-end graphic cards while keeping them cool and silent.

Two versions are available:

GTX285-HS-P891, for nVidia's original reference design P891
GTX285-HS-P892, for the recently released P892

Please make sure your card is the first revision to install this! There will be a 15% restocking fee even for store credit on this item due to high number of RMA returns and our time spent processing these.

The performance advantage of the MCW60 GPU cooler over full-coverage water-block solutions is well known among enthusiast users: improved thermal conductivity thanks to Swiftech's Diamond Pin Matrix, and less heat dumped into the liquid cooling loop coming from memory, I/O and power mosfets since they remain air cooled. So when coupled with the GTX285 heatsink, the pair provides a complete solution that is more economical than the average full-coverage water-block while offering superior performance where it really counts: at the GPU level!
