ARCTIC Accelero Xtreme Plus II
When running the Xonotic game at 1920 x 1080 immediately after Unigine Heaven, the ARCTIC Accelero Xtreme Plus II still was quieter and at a ~23°C advantage over the EVGA heatsink fan. During none of the testing -- even when overclocking -- did the Accelero Xtreme Plus II top 50°C in this open-air environment.
