GTX275 P897 GTX285 P891 GTX285 P892 Engineered in the USA Introduction: The GTX heatsinks are designed to cool surface mount components (memory, voltage mosfets, I/O chip) on nVidia's reference design GeForce® GTX200 series graphics cards listed below. They are designed to be installed in conjunction with our MCW60 VGA water-block and they allow the highest possible stable overclocks of these high-end graphic cards while keeping them cool and silent. Available versions: GTX275-HS-P897, for nVidia's reference design P897 GTX285-HS-P891, for nVidia's original reference design P891 GTX285-HS-P892, for the recenly released P892 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 GTX heatsinks, the combination 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!
