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 sit idle for a while, I checked the temperature of the processor. From the first graph, you can see with the DeepCool ASSASSIN 4S on top of the processor, my CPU idled at a temperature of 35c. Unsurprisingly, this is slightly warmer than the ASSASSIN IV WH. Changing the switch to quiet mode increased the processor's temperature by another degree. However, idle numbers do not give a full representation of what CPU coolers can do, so we started up the Prime95 tests to see the more pertinent results.

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 ASSASSIN 4S performed decently well with a maximum CPU temperature of 63c. Compared to the ASSASSIN IV, this cooler was still warmer, but this time by two degrees. However, compared to other coolers, this ASSASSIN 4S was generally competitive, staying close to its competition that employed two fans. In quiet mode, the processor did increase by an extra 2 degrees, but this is as expected. The DeepCool ASSASSIN 4S was more than capable in cooling off the AMD Ryzen 7 3700X, which meant the processor could hit its maximum boost frequencies during the test.

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 4S at around 3.5/10. It is slightly quieter than the ASSASSIN IV, primarily because the single larger 140mm fan does not create as high of a frequency of noise as opposed to a 120mm and 140mm pairing, which makes the whole cooler quieter. Under nominal loads, the cooler becomes whisper quiet, which is great.
