57 degrees is very respectable as a result with the processor at stock. Comparing to the others we have run on this CPU, it is only two degrees out of first in air coolers listed, and even outperforms the H80i when it is in Quiet Mode. Shockingly, as you will see in the noise level chart, the fan is running at a very low RPM to get this result too.
With the processor now overclocked, and the motherboard PWM still on control of fan speed, the 72.5-degree result is still splendid. The gap widens just slightly from the Noctua, adding a half of a degree, but at the same time, it is still able to hold up with the fat 120mm radiator of the H80i. Again, since the PWM fan curve favors silence over RPMs, the fan speed here was only around half of its potential.
In this test, we still have the processor overclocked, but this time we allow the fan to spool up to full speed. At this point, we were able to reduce the average of all of the cores another 3.25 degrees from our last result. As you are about to see too, even at full blast, we would not consider the Macho Direct to be loud.
Noise Level Results
The baseline for the fan is 300 RPM, and at idle we saw the fan spinning near 400 RPM for all of the testing, making it unheard while nothing was going on with the system. Once the stock testing was underway, the highest fan speed we saw in that thirty-minute run was 690 RPM, and at that time we were only getting 23dB of noise.
Even adding more voltage and speed to the processor with the overclocked setting applied, we were still very impressed with the lack of noise during this pass. Only 27dB is heard from the Macho Direct at this point, and the maximum fan speed for this round was only at 976 RPM.
Once we applied 12V to the fan, we did get the speed up to the rated top end, with AIDA64 reporting 1450 RPM for the majority of this phase of testing. Even so, there is only 35 dB of noise coming from the Macho Direct, and while it is just getting to an audible level for most users, inside of a chassis, most of it will be blocked from reaching your ears.
