The HD5850 heatsink is designed to cool surface mount components (memory, and mosfets) on ATI Radeon™ HD 5800 Series reference design graphics cards. It is designed to be installed in conjunction with our MCW80 VGA waterblock and allow stable overclocks of these high-end graphic cards while keeping them cool and silent.

Available versions

HD5850-HS, for Radeon™ HD5850 reference design boards
HD5870-HS, for Radeon™ HD5870 reference design boards

The performance advantage of using the MCW80 GPU cooler in combination with a heatsink compared to a 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, and power mosfets since they remain air cooled. In addition, this combination provides a complete solution that is more economical than the average full-coverage water-block while offering superior cooling performance at the GPU level.
