Testing

I will compare the three Noctua fans with a selection of fans from other competing manufacturers that i’ve tested before.

These are the Akasa Amber AK-183-L2B, Akasa (grey smoked) DFS122515L, Thermaltake TT-1225, Vantec Stealth SF12025L, GELID Silent 12, GELID Wing 12, Coolink SWiF 1201, SWiF2 921, SWiF2 92b, SWiF2 1201, SWiF2 120P and Antec Tri Cool 140mm.

Testing Methods

I used the sound pressure level meter below to test the db rating of the Noctuas at all fan speeds.


The sound meter used for testing.


Due to the sound level meter only registering a db rating of 50db+ i will have to adjust the sampling distance to allow the fan to register on the meter - after a few test runs it was decided to test the fan at each rated voltage at a distance of 2cm.

The 'damping of sound level with distance' calculator was then used to calculate the db rating at a greater listening distance. This will give a clearer understanding of the actual volume of the Noctua fans we have here.

The test will use a PC comprised of the following hardware:

For testing i used a hotwired ITX PSU which is a fanless silent model. This will provide power for the fan's without producing any noise interference itself.
