Acoustic Performance

Now let’s talk about the noise levels of the today’s testing participants. First comes the graph for Scythe Zipang 2 acoustics and its fan power consumption:

Obviously, the 140 mm fan of the Scythe Zipang 2 cooler is not only quiet but also pretty economical. We detected no parasitic noises during its work. The fan’s startup voltage is 2.4 V.

Now let’s compare the noise levels from all three top coolers participating in our today’s test session in the entire speed range of their default fans:

Approximately until 800 RPM mark Scythe Zipang 2 is the quietest. However, after this threshold its noise becomes stronger than that of Scythe Kabuto and XILENCE Black Hawk COPPER. The latter is overall the quietest of the three, because its dBA are lower at the same fan rotation speed.

Finally, here is the summary chart with the noise levels of all tested coolers in the same modes that were used during efficiency tests:
