Testing ProcedureAll testing is done at a room temperature of 23°C (73°F) with a 1°C margin of error. The coolers are tested with Turbo, EIST, and C1E enabled, which will allow the CPU to clock down to a low 1.6 GHz while idle, or clock up to proper speeds under stock and overclocked conditions. The retail Intel Core i7-4770K I use for testing at stock is set to load-optimized defaults with the CPU's voltage at a static 1.15 V. Overclocked, the processor is running at 4.2 GHz on the CPU and 3.9 GHz on cache, with respective voltages set to 1.20 V and 1.15 V. During all these tests, fans are set to run at 100% in the BIOS, with temperatures being recorded by AIDA64.
The idle test will consist of the CPU sitting idle at the desktop for 15 minutes. This will allow for a stable temperature reading that will be recorded at the end of those 15 minutes.
Wprime's and AIDA64's CPU test represent typical multi-threaded loads. Both offer consistent results, with one being a benchmarking application and the other a stability test. Both are run for 15 minutes before the peak reading during the test is recorded and taken as the result. This test lets enthusiasts know what temperatures they can expect to see with games and applications. Wprime is set to eight threads while AIDA64 is configured to stress the CPU, FPU, cache, and system memory.
AIDA64 offers maximum heat generation when set to stress just the FPU in the stability test, which will really push the CPU. This test represents extreme loads much like LinX, Prime95, and other extreme stress tests many users are familiar with.
At idle, the Raijintek Themis does well enough. It does not impress at stock, but I was surprised to find the Themis near the top, just 1°C behind the Phanteks PH-TC12DX, once the system was overclocked. It manages to beat the Cooler Master Hyper 212 EVO and NZXT Respire T40 by 2°C and 4°C respectively.
Typical Load Temperatures
In Wprime, things look as they should at stock. The Themis does well by tying the larger, more expensive Ereboss. It also once again beats the similarly-priced Cooler Master Hyper 212 EVO and NZXT Respire T40. This trend continues when overclocked, with Raijintek's cooler showing some serious budget muscle in my first typical load test.
The Raijintek Themis continues to show some impressive performance for its price in AIDA64's system-stability test. The lead it had early nearly slipped away at stock, but it managed to maintain the lead over the Hyper 212 EVO by 3°C when overclocked. The Themis only falls behind the Noctua NH-U12S by 1°C, which is impressive since Noctua's cooler commands double the price.
Max Load Temperatures
Now on to the worst-case scenario where the coolers are pushed to the limit. Temps skyrocket in AIDA64's FPU system stability test; however, the Raijintek Themis again delivered on performance by beating the Hyper 212 EVO by 3°C at stock and overclock. The NZXT Respire T40 is so far behind as to be of no concern. Once again, Noctua's NH-U12S gets shown up by Raijintek's Themis. A difference of just 1°C separates the two coolers while the price difference is massive. These test results easily make the Themis the new budget-performance king.
