I will test the thermal efficiencies of the Accelero Twin Turbo by stressing the graphics card with three consecutive runs of 3DMark06. I will run three seperate tests at 25% (low speed), 50% (mid speed) and 100% (high speed) fan speed. I will also record the GPU idle temperatures after 10 minutes of idle time. The recorded load temperatures will be taken from the maximum temperatures reached during the 3DMark06 stress test. The temperatures achieved by the Twin Turbo will be compared against the stock heatsink at 25%, 50% and 100% fan speed as well. The fan speed will be set using RivaTuner 2.11. Temperature monitoring will be handled by RivaTuner as well. Furthermore, I will test both the Twin Turbo and factory heatsink by overclocking the 4850s GPU and memory frequencies to their highest stable speeds. I will record the overclocked idle and load temperatures as well. All recorded temperatures will be in Celsius. Ambient temperature around the test system is 19.4 degrees.

The Accelero Twin Turbo was the winner in every test. The factory heatsink was clearly outmatched by a far more superior product. The temperature differences between the two products were as high as 36 degrees in some tests. At its best, the factory heatsink got within 6 degrees of the Twin Turbo. In addition, the Twin Turbo fans were much quieter than the factory fans at every speed setting. At any speed above 50%, the factory fan was simply unbearable. AIso, I decided not to test the stock heatsink at an overclocked load with only 25% fan speed, in fear of damaging the card.
