We measured the level of noise generated by our today’s testing participants from a 3cm, 1m and 3m distance. The results are given on the diagram below:
Unfortunately, the tested ASUS coolers did not that well in terms of acoustic characteristics. As the CPU temperature increases, the cooler fans start rotating faster very quickly, which lowers acoustic comfort dramatically. None of the three ASUS coolers we tested today could boast comfortable or at least acceptable level of noise under maximum CPU workload. In idle mode, all of them are very quiet and not even noticeable against he background noise from a very quiet system case. If we compare the acoustic data of all three coolers with one another, then ASUS Silent Square EVO will be a little quieter than ASUS Triton 77 or Silent Knight II. Could be the fan between two heatsinks that tells on the results here.
Three ASUSTeK CPU coolers we tested today proved to be very stable mainstream solutions. If you ask me, I wouldn’t recommend Triton 77 for overclockers, because it will not do well on top of a seriously overclocked processor. At the same time, keep in mind that this cooler is cheaper than Silent Knight II or Silent Square EVO. These two coolers are enhanced modifications of the previous models. They will provide comfortable thermal mode in majority of applications and will add a nice touch to your system case with their original design and modding highlighting effects. However, it is only possible if you agree to put up with pretty loud noise they generate at work. Anyway, the choice is yours, as always.
