All tests were run in our custom-built computer to best reflect real life performance. The computer remained in the same place and room for all tests. The ambient temperature of the room was roughly 18 degrees Celsius. The thermal paste applied to each cooler was stock respective to their manufacturers to rate its performance. Sufficient time between testing was applied for the paste to settle. The fans on all heatsinks were connected to the same 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 sixteen worker threads for a minimum of fifteen minutes and recorded when the temperature was deemed stable. The Reeven Justice was tested using the stock Zephyros II fan sent from the factory. The performance was compared with the AMD Wraith Prism that comes with the Ryzen 7 3700X. The purpose of this comparison is to find the relative performance between comparison. The temperature results for each cooler was measured with CoreTemp, which records the CPU’s integrated thermal sensor for maximum accuracy. Each temperature result was calculated by taking the maximum value of the cores inside of the CPU.

In the idle test, the Reeven Justice II RC-1207 pulled ahead by 4 degrees Celsius. The Justice II RC-1207 stabilized at 46 degrees Celsius. This temperature might seem high, but this is pretty good given that the average temperature of a stock Ryzen 7 3700X is around 50 degrees Celsius when idle. There was a slight difference in temperatures between the Reeven Justice II RC-1207 and the AMD Wraith Prism likely because the Justice II RC-1207 is larger in size compare to the latter. The cooler’s performances were satisfactory, but idle tests aside, let us look at the test that really matters.

After enough time of stressing the CPU, I was able to push these two coolers to see what they could do. After about 25 minutes, the Reeven Justice II RC-1207 was able to maintain a constant temperature of 78 degrees Celsius. The Justice II RC-1207 came in 6 degrees lower than the stock AMD Wraith Prism. Note the sizes between these two coolers are quite noticeable as the Justice II RC-1207 has a larger heatsink and fan. Additionally, the design of the Justice II RC-1207 is a lot better in terms of the direction of air flow. Given these factors, it is obvious that the Justice II RC-1207 would come out on top. The temperature difference was pretty noticeable in this case. Having a better design will always produce better performance. The Reeven Justice II RC-1207 is capable of keeping the CPU reasonably cool in heavy workloads.

Taking noise into consideration, I am the type of person to get distracted by small and irritating noises. In my setup, I am running the cooler and its fan with an additional four fans inside the case. On a scale of 0 to 10, where 0 is silence and 10 is an explosion, I would rate the Reeven Justice II RC-1207 a 2.0 when idle and a 2.5 when under heavy load. The Zephyros II was very quiet when idle. During heavier loads when the fan is spinning at a higher RPM, the difference in noise was barely noticeable. The Justice II RC-1207 has great performance in both temperature and noise levels.

Taking all of this into account, the Reeven Justice RC-1207 is a well-made CPU cooler with a 120mm fan due to the fact that it had good cooling performance and very acceptable noise levels.
