Without further ado, here are the test results. The average values are calculated out of all three test runs per fan, and per configuration.
At 2.8Ghz the Hyper 212 Evo cooled the i7 920 with relative ease.
At 3.6Ghz we can see a definite increase in temperature with the Hyper 212 Evo, later on we will see what the increased fsb and voltage did to the thermal throttling of the cooler.
The 4.0Ghz average temp chart, shows The Cooler Master Hyper 212 Evo can’t quite dissipate the heat the i7 920 is putting off. Throughout our testing, the the temperature slowly rose to 99c, at which point throttling occurred.
The Cooler Master Hyper 212 Evo is well-equipped to handle normally-clocked CPUs silently, even when fully loaded, but as our tests show, was not designed for the greater thermal loads generated from heavy overclocking. Given the incredibly space efficient size of the heatsink and its single, low-noise fan, this is neither a surprise nor a disappointment.
The Cooler Master Hyper 212 Evo performed as expected, at lower clock speeds the stock and San Ace fans performed equally, the Gentle Typhoon fans caused slight throttling. The 3.6GHz tests, caused throttling in almost all our tests, with only the San Ace fans managing not to throttle at that speed. It should also be noted that the stock fan only caused slight throttling. At 4.0 GHz,s we see throttling across the board, with the San Ace once again performing the best, followed by the stock fan, and then our Gentle Typhoon fans.
