Acoustic Performance

The acoustic performance of all our testing participants was measured in their entire fan rotation speed range following our testing methodology described above. The results are summed up in the diagram and table below:

The results for Swiftech H2O-X20 Edge tested with one and two fans only have little practical value, because I doubt that anyone is going to use this liquid-cooling system with one or two disconnected fans. However, they have also been included into the table and diagram for your reference. We can’t praise Swiftech for low level of noise, because it is really quiet only at 650 RPM and acoustically comfortable at 900-950 RPM. For example, Thermalright TY-140 fan produces the same 36 dBA of noise at 1150 RPM, and even though there is only one fan, the difference is quite noticeable. At the same time I have to say that when Swiftech H2O-X20 Edge fans work at low rotation speeds, we can clearly hear the impellers beating (and not only on the defective fan), which adds more discomfort to the acoustics regime of the new system. In this case you can’t really hear the pump at the low 2150 RPM. Even at the medium 3100 RPM its noise vanishes in the sound of the fans. However, at the highest speed of 4500 RPM the noise from the pump becomes truly unbearable.


Of course, Swiftech H2O-X20 Edge is a high-quality and high-class liquid-cooling system with incredible efficiency. If you decide to purchase Swiftech H2O-X20 Edge kit, matching the best components into a complete high-efficiency system will become extremely easy. Besides, you will also save about 4100, compared to what you could pay if you decided to purchase all components separately. Moreover, the new H2O-X20 Edge allows numerous installation options, is universal on Intel platform, although for AMD platform you will need to purchase an additional water block retention kit. In addition to that, this Swiftech system is very easy to assemble and fill. We are proud to award Swiftech H2O-X20 Edge with our Editor’s Choice title as the best liquid-cooling kit available today:

Nevertheless, Swiftech H2O-X20 Edge has a few drawbacks, which we have to point out again. First of all, it desperately needs quieter fans with PWM control or rheobus for manual rotation speed adjustment, which could be even better. They should also use a single cable for connecting all three fans. Secondly, even though the high-performance pump does support PWM control for the rotor, its speed range is very small, so the pump often works louder than necessary. Thirdly, we have to point out that it would make sense to include a refill funnel, an AMD retention kit for the processor water block and better thermal paste. Other than that, Swiftech H2O-X20 Edge is totally fault-free and can definitely become part of your next liquid-cooling system.
