Testing and Results
Testing was done at a stock clocked state and an overclocked state. Maximum fan speeds were used due the the quiet nature of the Accelero Twin Turbo II.
The HIS Radeon 7870 from this review was used.
Ready for the results? Me too:
Keep in mind that 100% fan speed was used for all testing. While this was not exactly loud on the Accelero, it was not quiet either. But compared to the stock cooler temp drops are massive. The stock cooler just completely gets destroyed at load.
Next we bumped the voltage to the maximum level on the card and started overclocking.Using the stock cooler we were able to get to about 1210mhz on the core. But using the accelero we were able to get to 1268mhz-core. 50mhz bump in frequency is not bad at all!
The cooling difference was huge between these two coolers. Keep in mind that this is a distance to ambient. So add about 25*C on each of those and you get the temperatures that were logged. The stock cooler was shutting off from time to time from overheating even with maximum fan speed. On the other hand the Accelero was rock solid and gave great temperatures.
