To test the cooling performance of the Thermalright Spitfire & VRM-R5 combination, I will be using the very demanding Furmark GPU stability program. Furmark will be for up to 20 minutes and the tempratures will then be checked using the latest version of GPU-Z. For idle temperatures, I will let the system run in an idle state with only minimal background programs running for up to 20 minutes and will again check the temperatures using GPU-Z. This will give an accurate idea of how the Thermalright Spitfire & VRM-R5 combination will compare to the stock cooling solution that comes with the graphics card. This combonation will be tested three different ways, to best replicate how it will be used in real life situations. The first test I will run is with the cooler installed passively and with no additional side cooling. The next test will again be passive, but in this test I will use an additional side fan. The last test will be with fans installed on both the case and heatsinks. All temperature testing will be performed in the mid-sized NZXT Tempest EVO case.

The cooling performance from this VGA cooling combination was just amazing. When comparing the Spitfire against the stock cooler, there was a huge 38°C difference when the stock fan was set to auto and a 18°C difference when the stock fan was set at full speed. If you have ever heard a HD5870 fan at full rotation, you know just how loud it is, so the fact that the Spitfire was 18°C to 38°C cooler and nearly silent with the X-Silent 140 fan was phenomenal. Even more impressive though, was that the Spitfire outperformed the auto setting of the stock cooler even passively, with the temperature being a full 12°C lower at full load. The cooling of the VRM-R5 was equally impressive and even when it was used passively, still out performed the stock cooler regardless of the fan speed. Also, a nice bonus was that, even when the side case fan was removed, the 140mm fan on the Spitfire helped reduce the chipset and processor temperatures.
