To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article (October 2016) for more information.
Roughly nine degrees from the top of the chart does not bode so well for ARCTIC at this point. While far away from the throttle point, we know of seven or eight coolers in the chart that do better with similar cost involved. So, even though 59.75-degrees is not that bad in the large picture, you can have better efficiency with many other choices.
With the stock results what they were, we did not have high hopes for its ability to cool the CPU with the overclock applied, and it seems we were not wrong. 77.25-degrees is lackluster performance in our opinion, as again, it is still handily beat by roughly seven degrees by the Scythe Mugen 5.
Allowing the fans to climb way up into the obnoxious amount of noise level, it did not seem to pay off big enough for the effort. While this does show that ARCTIC set the PWM fan curve well, it also shows that the best results we could get were still way behind the comparable coolers in the chart.
Noise Level Results
The noise level isn't exactly silent when PWM is in control with the processor running at default clocks. We can see that the 32 dB rating on the chart is towards the bottom, so if limited noise is a priority when selecting a cooler, this may not be what you are looking for. Doing the math, as our software read 1700 RPM at this time, we calculated actual speed was around 1300 RPM.
We again did some math to sort out that while the fans are shown to be turning at 2100 RPM, the reality is closer to 1400. Listening for the max output of the fans at this time, we registered 37 dB on the meter. This is not horrible for a result, but again, many coolers can do more with less.
If you are into drowning out the rest of the members in the place where you live, you may want to allow the fans to run at full speed. Reading 2700 RPM with software, the match says they topped out at the 1800 RPM max of the specifications. For the typical user, however, we feel that there is no need for this sort of noise, especially when it doesn't bring the Freezer 33 up to the performance of other, much quieter options.
