GeForce GTX 260
Unfortunately, Thermalright doesn’t offer any VRM heatsinks for GeForce graphics cards that is why all alternative coolers shows m ore modest results on these graphics cards:
The stricken out value on the diagram indicates that the test was terminated to prevent the graphics card from getting overheated. During the tests on GeForce GTX 260 we notice a huge difference in graphics processor cooling between T-Rad2 GTX and Accelero XTREME 280 GTX. The reason is quite simple and in fact typical of Thermalright solutions: the uneven base that contacts the GPU heat-spreader only in the center, while the base of Accelero XTREME 280 GTX covers almost its entire surface. As for the VRM components, things are not that good by both coolers, just as by the stock GeForce GTX 260 cooler in automatic fan mode. At the same time it is important to understand that the graphics card works at far not the nominal frequencies and besides, you don’t really come across the same operational load in games like the one created by FurMark in this test.
