TEST RESULTS

First the EN8600GT Silent was tested with the stock cooler. It's a simple heatsink comprised of a copper base connected to a single heatpipe, and thick aluminum fins.

With the system fan at 7V, the GPU temperature with the stock heatsink was a sizzling 98°C, which also seemed to affect the CPU temperature. Turning up the system fan speed resulted in significant improvements.

The Accelero S2, with 30°C to 35°C improvements across the board, makes the stock heatsink look foolish. The results were also better than the EN8600GT OC Gear card which we tested on our old test platform. That card used a Zalman-type cooling solution, with which we recorded a load temperature of 70°C @ 22 dBA. Even after accounting for the temperature difference between our old test platform and our new one (about 5°C), the S2 is still slightly better. Any time a passive heatsink can match or beat the performance of an active cooler, it's a great achievment.
