The graph below shows the acoustic readings taken off the testing participants with their default fans:
Out of four coolers equipped with a 120x25 mm fan Deep Cool Ice Warrior is the quietest: up to 1100 RPM its fan remains extremely silent and works in a very acoustically soft and pleasant range. It must be the benefit of the rubberized frame that reduces the vibrations from the fan to the heatsink and thus lowers the overall noise. Deep Cool Ice Blade Pro cooler is just a little louder, but it remains acoustically comfortable at up to 1050 RPM. However, its fan can’t boast creating stable and even sound pressure, which you can clearly see from its broken acoustic curve. Besides, it becomes one of the worst at low fan speed.
The thick fan of Deep Cool Killer Whale Premium is a little noisier, but without any abrupt changes in its acoustic performance, like the ones we observed by Ice Blade Pro. Akasa venom cooler appears to be the noisiest of the four. It remains acoustically comfortable only up to 950 RPM, and after that its fan starts to buzz. As for the Acoustic performance of ThermoLab bada2010, despite its smaller fan, it sounds a little less pleasant than the today’s leader – Deep Cool Ice Warrior. Although it will suit standard system cases just fine at up to 1500 RPM rotation speed, unless you are really looking for an ultra-low-noise system.
It is almost impossible to pick just one cooler out of five new products we have just discussed. I am sure you wonder why? Well, it is all very simple. ThermoLab bada2010 ($39), unlike Baram2010, can’t boast super-efficiency or low noise and costs too much for a product of its class. Of course, it is relatively compact and universal, but these are no longer unique features these days. Deep Cool Ice Warrior ($49) boasts a very good and quiet fan, but it yields to its less expensive brother, Ice Blade Pro cooler ($39), in performance. The latter could be considered the leader of our today’s test session, if it hadn’t been for the fourth cooler, Akasa Venom ($44), which proved remarkably efficient, but at the same time was the noisiest of all today’s testing participants when tested with 120x120x25 mm fans. Finally, Deep Cool Killer Whale Premium ($59) boasts extremely appealing exterior and beautiful LED lighting, but can’t offer exceptional performance or acoustics. Nevertheless, we hope that our today’s review will help you narrow down your search for that perfect cooler after all.
I also have to say a few words about the tests performed on AMD platform. Although we used the top AMD Phenom II X6 processor, its heat dissipation is quite modest even after we overclocked it beyond 4 GHz compared to overclocked Intel Core i7, therefore, the difference in cooling efficiency among the today’s testing participants is smaller. Moreover, coolers can usually be installed in only two ways on AMD processors, which limits our ability to study their cooling efficiency more diversely. Besides, the way the CPU is locked in its socket doesn’t let us estimate the quality of contact between the CPU and the cooler base from the thermal paste imprint, because we have to turn the cooler slightly during dismounting to avoid damaging the CPU. It produces a smudged imprint. Nevertheless, we will continue to include AMD platform tests into our cooler reviews from time to time.
