Cooler Master Hyper 612S CPU Cooler reviewed

by on16 August 2011


Mounting the Hyper 612S is made easy with the new mounting system, which comprises from only a few parts. The hardest part of mounting the cooler was removing the glue that was left after taking the protective plastic off.


We tested the Hyper 612S on EVGA’s FTW3 motherboard in Corsair Obsidian 800D case, which has three 900 rpm fans. Room temperature was at 22°C. We measured temperatures at Core i7 930’s reference clocks (2.9GHz) and after overclocking to 3.6GHz.




We first tested with the reference fan and then added another one (Thermalright TR-TY-14cm 1300 rpm).



Cooler Master’s Hyper 612s is the most affordable cooler in the table, but it still holds its on quite nicely. The test results were made with the fan running at 1300rpm.


Hyper 612S comes with one fan (A12025-13CB-3BN-F1, DC12V, 0.16A), which was supposed to be quiet during operation. While the fan rpm can be decreased from 1300 rpm to 900 rpm with the adapter, we heard a quite unpleasant buzzing noise coming from the fan’s motor. As far as airflow noise goes, the fan is among the quieter we’ve tested thus far. In fact, when running at 900rpm, you won’t hear it, which is more than we can say for the buzzing sound.
