Test System Setup
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 for that information.
Starting things out without an overclock, we found the processor idling at 25.75 degrees, and is a pretty average result across the board. When we applied the testing, and the time had elapsed, we found the 4770K to have reached a maximum of 50.75 degrees.
Compared to others on the list, we expected this cooler to fall between the pair of Enermax AIOs, and it did exactly that.
With the overclock applied, our idle temperature went up a single degree. As we ran the rounds of testing in various orientations, we got an average result of 72.91 degrees across all cores.
While the results here are not horrible, even with the high pressure fans, the silence in the design is holding this cooler back in our opinion, as we did expect slightly better results.
Noise Level Results
With limited voltage allowed to the fans, and AIDA 64 showing us the RPM was right at 1200 RPM, we found that the fans were delivering 31 dB of noise at this time. Not exactly dead silent, but nothing to complain about here either.
Letting the Kelvin T12 do all that it could do with our 4770K, we allowed all of the voltage we could deliver, and found the fans turning at 1741 RPM. When we hear 52dB, we don't think of a silent fan, but this is what we found in our testing.
