Noise testing
When we test
the noise level of our case fans we do this in an anechoic
test chamber under free air condition. The chamber used for
testing this fan background noise is 19.2 dB(A). Reading is done using a Spectrum Analyzer.
The below
set-up is used and these are the most common conditions for
these type of tests and hence you should always be aware
when a manufacturer is claiming dB(A) values that are lower
then 15 dB(A). Because how where they able to measure this?
We provide the real figures, from the actual tests. Can it
get any more reliable…? Judge for your self.
