120mm Fan Testing on an MCR120 Radiator Round 6

[Martinm210]

Here is a quick look at a few of the fans I tested in Round 11 at similar (550-590 air flow speeds), but haven't published yet. I liked the noise quality coming from the Kama Flow 2, Be Quiet, & the Phobya fans, but the GT was still prevailing on noise levels when radiator mounted. They all had good smooth air like smooth sound, but the GT is practically absent of air noise from it's blade design giving it the lowest noise level. This does however leave the bearing noises and other not so pleasant noises to be more apparent so some users don't like the GT sound quality and I can understand that.

The meters are left to right (Exhaust Chamber Air Flow in Feet Per Minute | Noise Level dbA | Voltage at Fan Plug | Speed in Hz (typically Hzx30=RPM))


The Be Quiet does require a bit more RPM to reach the same air flow levels. The Kama Flow 2 was pretty good with that, not quite to GT CFM/RPM levels but decent.

The Phobya fans have really good noise quality and very similar to that of Noise Blocker fans, but just not keeping up with GTs on noise level either.
