Specification and Test Methodology
To put CPU cooler performance into perspective we're benchmarking using a high-end Intel Haswell test platform. A detailed description of the CPU cooler being reviewed, our test platform and all comparison coolers can be found in the tables below.

To get a feel for how well all of the above coolers compare, we start by running our Core i7-4770K at its default frequency and use HandBrake to encode a large 4K video clip, putting full load on all four cores/eight threads. Temperature is logged throughout the duration of this workload and in order to provide a stabilised reading we then calculate an average temperature across all cores from the last few minutes of encoding.
We then repeat the same test, only this time with the Core i7-4770K processor overclocked to a modest 4.4GHz, with voltage increased from 1.175V to 1.225V.
Actual CPU temperature is recorded, but to take into account any temperature 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 all three pre-installed fans; a 200mm front intake; a 200mm top exhaust; and a 120mm rear exhaust. All chassis fans are set to run as 'silent' from within the Gigabyte BIOS, while the CPU cooler is set to a 'normal' profile.
Each cooler is configured for optimum performance as per the manufacturer's recommendations, and any fans connected to a radiator are configured 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).
The Deepcool Gamer Storm Lucifer follows the Corsair Hydro Series H75 as only the second cooler to be put to the test on our new Intel Haswell test platform. The two comparable results will showcase the difference between high-end air or liquid cooling, and we will be adding other competing coolers in due course.
