Benchmark Process

To get a feel for how the above coolers compare, we run our Core i7-4770K processor overclocked to 4.4GHz. In order to push the coolers, voltage is upped to an above-average 1.2V and memory operates at 1,866MHz using the built-in XMP profile.

Temperature is logged while a large 4K video clip is encoded in multiple passes using the freeware HandBrake utility. The workload tasks all four cores/eight threads for a prolonged period, and in order to provide a stabilised reading, we then calculate the average temperature across all four cores from the last few minutes of encoding.

Actual CPU temperature is recorded, but readers should note that the above coolers are tested over a period of months and to take into account any fluctuations in our lab, we also graph the delta temperature - that's CPU temperature minus ambient temperature. And, last but not least, to give you an idea of cooler acoustics, we use a PCE-318 noise meter to measure overall system noise in both idle and load states.


Our Corsair Graphite Series 600T chassis is set to run with three installed fans; a 200mm Corsair front intake; a 200mm Corsair top exhaust; and a 140mm Noctua NH-A15 rear exhaust. The front and top fans are configured to run quietly using a custom DC profile from within the Asus BIOS, while the rear exhaust and CPU cooler are set to the 'standard' PWM profile. If a pump is installed, Asus Qfan control is disabled to ensure constant running at full speed.

Where necessary, any of the three aforementioned chassis fans are removed to make way for radiator installations. Any fans connected to a radiator are configured as per the manufacturer's recommendations. If none are made, fans are set to draw air in from outside the chassis (hereby ensuring that the delta between the air temperature and the temperature of the radiator is maximised).
