The GTX 400 series heatsinks are designed to cool surface mount components (memory, and voltage mosfets) on nVidia's reference design GeForce® GTX400 series graphics cards listed below. They are designed to be installed in conjunction with our MCW60 or MCW80 VGA water-blocks and they allow the highest possible stable overclocks of these high-end
graphic cards while keeping them cool and quiet.
GTX480-HS, for nVidia's GeForce GTX 480 reference design P1022
GTX470-HS, for nVidia's GeForce GTX 470 reference design P1025
Features and benefits
The performance advantage of the MCW80 GPU cooler over full-cover 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. Thus, when coupled with the GTX-400 heatsinks, the combination provides a powerful cooling solution that is generally more economical than the average full-cover water-block while offering superior performance where it really counts: at the GPU level!
Another important factor in choosing this type of hybrid cooling solution is that when new graphics cards models are introduced, the Water-block itself can usually be re-used. Numerous users have testified in forums to have been keeping their MCW60 upwards of 5 years, and re-used them with several generations of graphics cards!
The GTX-400 series of heatsinks are custom Aluminum extrusions, and they are precision CNC machined to allow optimum TIM joints with the hottest components such as the voltage regulator modules, where high performance thermal grease is to be used. Less heat intensive components such as memory receive pre-applied thermal pads, as shown below.
