Results – relationship between Delta T and noise
What is better than one liquid AIO cooler? Two liquid AIO coolers. Today it’s time for the Gammaxx L360 V2 and Castle 360RGB V2 coolers. Both are among the top of DeepCool’s lineup, both use 360mm radiators, and both also feature Anti-Leak technology. However, our standardized noise methodology is generally very strict with AIO coolers. So I’m curious to see how Gammaxx and Castle perform in our stress tests.
Results – relationship between Delta T and noise
From the measured data it is clearly evident that the correlation between Delta T and noise is more or less linear as expected. The missing value of 36 dBA is due to the pump noise, which was about 37–38 dBA for both coolers, so it was not possible to perform tests at this noise level. However, the pump noise is still very low and provides pleasantly quiet operation even without the possibility of speed control.
However, the constant temperature difference between the Gammaxx and Castle is quite interesting. I expected a little less variation, because the used fans and radiators are practically the same. My personal hypothesis is the use of anti-vibration pads on the fans, which you can find on the Castle 360RGB V2. This is because these pads can create a small gap between the radiator and the fan where airflow may escape, in theory reducing cooling efficiency. Unfortunately, I didn’t have time before the deadline to run another set of tests to verify this hypothesis.
