All tests were run in 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 pastes were given a proper amount of time for them to fully settle. The fans on all heatsinks were directly connected to the motherboard's 4-pin connector. The test computer was turned on and 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 ten 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 sit idle for a while, I took a look at HWiNFO's CPU temperature readings. The first graph are the idle results, and you can see the DeepCool AK620 idled around 34c with two fans attached and 36c for a single fan. This was the same result as the Noctua NH-U12A, which is a pretty good cooler in its own right. It is a bit warmer than larger coolers like the MA624 Stealth, although this is not too surprising. Even so, these idle results do not speak too much on their own, so I fired up Prime95 to run tests and see the load results.
Once again, after a sufficient amount of time to keep a heavy load on the processor's cores and threads, you can see how each of these coolers performed under full power. The DeepCool AK620 peaked and plateaued at a temperature of 62c and 64c for double and single fan configurations, respectively. These were the same results as the NH-U12A again, which is solid. Otherwise, all of the other coolers kept this processor around the same mark, which means the AK620 truly is a strong performer against all of the coolers here. We were also able to observe the same boost frequencies from the processor throughout the test across our coolers, indicating we still had more than enough headroom on these solutions.
For the sound analysis section of the DeepCool AK620, on a scale of 0 to 10, where 0 is silence and 10 is very loud, I would rate the DeepCool AK620 at 2.5/10 during nominal loads, and around 5.0/10 under full load. Despite only being an air cooler, I noticed the fans emitted a higher pitched hum when there was a large load placed on the CPU. As higher pitched frequencies are more noticeable to the human ear, the overall noise was a bit more apparent and slightly louder than I liked. The fans still generally stay decently quiet under typical loads, but those with more sensitive ears may hear this cooler on a day-to-day.
