Today we have something a bit different for you from the GPU world: aftermarket cooling. Thermalright sent over a complete aftermarket GPU cooling kit for our Radeon 5870 containing 3 of their products: their Spitfire GPU heatsink, their VRM-R5 VRM heatsink, and their X-Silent 140mm fan, which combine to form one truly monstrous GPU cooler. Thermalright claims that they got a 32C reduction in the load temperature of a Radeon 5870 in their labs, so let’s put this to the test and see if their latest cooler is as good as they claim it is.
