We measured the noise from our testing participants in the entire supported speed range of their fans following the methodology described above. The results are summed up on the following graph:

Our regular readers already know that Phanteks PH-TC14PE is equipped with two relatively noisy fans that is why both Swiftech cooling system do not seem loud against Phanteks’ background. Moreover, the difference in acoustic performance between the junior and the senior models is relatively small, even though Swiftech H2O-220 Edge HD does indeed work quieter. At the same time we have to point out that both systems remain within acoustic comfort zone up to 930-970 RPM and very quiet up to 770-830 RPM. The fans produce no crackling, beating or vibrations or parasitic sounds of any other sort. As for the pump, it can be clearly heard at the maximum speed, but even then it doesn’t sound annoying. And as I have already mentioned above, due to PWM support its rotation speed may be lowered to a very quiet level without any efficiency losses.


As we have just found out, Swiftech H2O-X20 Edge HD are an enhanced and improved modifications of the super-efficient Swiftech H2O-X20 Edge systems with excellent reputation. Both new systems are equipped with a third revision of a radiator with additional in and out holes, improved water block supporting all contemporary platforms and available in two different colors, more reliable and secure clamps, highly efficient thermal paste and ready-to-use cooling liquid instead of a coolant concentrate they used before.

At the same time, these systems didn’t become more expensive, but on the contrary, are even cheaper than their predecessors, Swiftech H2O-X20 Edge products. The new systems deliver unprecedented efficiency, unattainable even for the best air-coolers. This is primarily related to the Swiftech H2O-320 Edge HD system that can cool the processor 10°C better than Phanteks PH-TC14PE. Swiftech H2O-220 Edge HD is a little more modest, but also defeats the best air-cooler. However, if you decided to go with liquid-cooling, we believe it makes more sense to purchase the senior model, Swiftech H2O-320 Edge HD, which is capable of delivering unprecedented cooling efficiency.

Therefore, we are proud to award both Swiftech H2O-X20 Edge HD systems with our Editor’s Choice title:
