All tests were run on our custom-built computer to best reflect real life performance. The computer remained in the same location in the same room throughout all tests. The room temperature in our testing lab was around 22c. Stock thermal paste respective to all coolers were used to rate its performance. All thermal pastes were given a proper amount of time for them to fully settle. The fans on all heatsinks were connected to the motherboard's CPU 4-pin fan header. The test computer was turned on and left idling for at least one hour for the idling tests. High CPU load results were obtained using the Prime95 in-place large FFTs test with a maximum number of worker threads for the tested CPU for a minimum of 10 minutes or until the temperature was deemed stable. Temperature results were measured with HWiNFO, which reports the CPU's integrated digital thermal sensor for maximum accuracy. Each temperature result was calculated by taking the maximum value of the cores inside the CPU.
After letting my computer idle for a while, I checked the temperature through my monitoring software. From the first graph, you can see the DeepCool ASSASSIN IV WH idled at a temperature of 34c. This is practically tied with every other cooler on this list, with only two coolers getting a degree less. Even so, I am glad to see that at idle the ASSASSIN IV WH was capable of keeping everything cool while staying relatively quiet. However, idle numbers are not representative of what CPU coolers are truly capable of, so we started up Prime95 and ran the tests to see more useful numbers.
With more than enough time to load the processor, you can see how all the coolers performed with the peak temperatures recorded. From here, the DeepCool ASSASSIN IV WH performed well with a maximum full load temperature of 61c. This was the best air cooler result we have seen to this point, tying the Noctua NH-U12A chromax.black. Only the larger Thermaltake TOUGHLIQUID Ultra 360 AIO liquid cooler with its three 120mm fans was able to eke out a single degree better. There were no signs of throttling as the cores were able to hit and sustain their maximum boost frequency.
As for the sound analysis section, on a scale of 0 to 10 where 0 is silence and 10 is very loud, I would rate the DeepCool ASSASSIN IV WH at around 4.0/10 under full load. I found everything to be decently quiet in operation, even when it was moving at full speeds. The two fans do create a slightly higher frequency tone when moving, which makes them audible at times. Even so, the output was manageable and not distracting in everyday use.
