Noise Level Results
For the stock testing, and with the fan spinning near 1200RPMs, there is very little to be heard of the Gabriel, as it registers at 29dB on our meter. Since most SFF chassis tend to end up as a HTPC, this is a solution worthy of that task, and should not be audible from any distance over a foot away from the chassis.
As we add full power to the fan and it now spins at 1840RPMs, the sound level definitely picks up a fair bit, as we got a reading of 55 dB at this point. To be really honest, if you are building something lower powered, it is highly unlikely that you will need to run the fan this loudly to keep the CPU in the "comfortable" range, with much less noise produced.
