NZXT F140RGB CORE 140mm Fan Review

Output Noise

I use a Class 1 Bruel & Kjaer 2270 G4 sound analyzer equipped with a Type 4955a microphone with a dBA-weighted dynamic range of below 6 dBA and up to 110 dBA. All tests are conducted inside a hemi-anechoic chamber with a noise floor close to 6 dBA and an ambient temperature of 25–28 °C. The test subject is placed a meter from the sound analyzer.

Full & 70% Speed

Despite its low maximum speed, the output noise is high compared to the rest of the fans included in the respective graphs.

Speed (Percentage) – Noise

I use a different setup to drive the fan for noise measurements, so there might be a difference in the readings of the Longwin machine, especially in the max fan speed reading.

  1. Thank you for another great review! Do you have any plans of testing smaller fans? I have a HTPC using a Silverstone GD09 case and it uses 2 80mm fans for exhaust. I’m trying to pick the best fan but as you have shown I can’t just go of the specs listed on the box. Thanks again and take care.
