Deepcool Gamer Storm GF120 Review

Testing Setup
I ran the fan through its paces. Deepcool sent me just one, so if it fails its testing, we won’t know if it is just this specimen or the fan as a whole. Ideally, a company would send two for review – just in case. But we will test this fan.

First off, the fan goes on a foam stand in free air to measure its RPM and the sound pressure level at 10cm. To convert to a standard 1m, you subtract 20 dB. The advantage of a close-in measurement is that you have the best chance of measuring the fan’s own SPL. This can be an issue when the fan is quiet and the ambient is typical silence as heard by the human ear. On the night I did the testing, my basement had an ambient SPL of 30-30.5 dBA.



SPL was measured with a Tenma 72-942 SPL meter. This will measure sound pressure accurately down to 30 DBA. The fan was placed on a test box, with an inlet fitted to the fan and an outlet that was 116mm. In the outlet I placed the measuring head of an Extech AN100 Anemometer. This averages ten CFM readings.

The fan was tested at 12v, 7v, 5v (readily obtained from the PSU) and the minimum RPM I could get from my motherboard’s PWM controller.

The fans were tested first without obstruction, then with an aluminum mesh dust filter. Finally, the fan was tested as it pushed air through a 30 fin per inch GT Black Stealth radiator.
