Cooler Master GeminII S524 VER.2: Fan Noise Measurements
As per request from many members of the enthusiast community, Benchmark Reviews has added noise measurements to our CPU cooler testing methodology. Each test is conducted in a noise isolated room, during the night time to avoid any minor disturbances caused by normal daytime activities near our location. Our base ambient temperature was measured at 15 dB for each of our tests. Noise was measured using a Brüel & Kjær type 2225 sound level meter located at 1 meter from the fan/fans. Fans were placed so that the axis of rotation of the fan is perpendicular to our line of measurement. For our dual fan noise measurements, fans were placed in series (facing each other) with a 10 cm gap between them. All fans were tested at 12 Volts.
The fan Cooler Master provided with our sample of the GeminII S524 Ver. 2 is a Silencio 120 mm PWM fan, which is the newest addition to Cooler Master’s fan line-up. At 26.8 dB it is a clear improvement over the stock fan included with our sample of the Cooler Master Hyper 212 EVO. At the 120 mm level it is still beaten by the Yate Loon variant by more than 5 dB which is an obvious difference. Like it’s name indicates, the Silencio 120 mm PWM fan scores above average in our noise measurement test.
