The GTX275 heatsink is designed to cool surface mount components (memory, voltage mosfets, I/O chip) on nVidia's reference design (P897) GeForce® GTX275 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.
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 GTX275 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!
For user convenience, the Heatsink is shipped with pre-applied thermal pads
The GTX275 heatsink is compatible with nVidia® reference board number P897.
The nVidia® reference board number is usually printed on the back of the circuit board, in a code located below the nVidia logo, as can be seen below (example is provided for the GTX285 P891 reference design)"
