Cooler Master rate the Turbine Master fan as generating 35 cfm airflow at a speed of 800 rpm, aided by the radical 16 blade design. At this given speed the fan is said to emit 13.83 dBa of noise. This is an extremely low level of noise and difficult to accurately measure. Even in our sound stage room electronic devices can emit ambient noise which can interfere with the results.
In this instance we have no need for a system so we are using a silent power supply hooked into the fan. The room rates as 21dBa – the air conditioning unit in the very far corner of the room causes this.

The Cooler Master Turbine Master fan did not cause our recording equipment to measure anything additional to the final ambient result. This is one of the very few fans that we can state only produces ‘whisper' levels of noise. This noise rating is very close to the Enermax TB Silence Fan that we tested in July last year.
The video below is not a measurement of noise, but the fan in action. We attached a small, high sensitivity microphone to the rear of the Turbine Master chassis to record the airflow over the mic head.
There is a high level of airflow being generated, especially for a ‘silent' fan design. We have no way to precisely measure this, but Cooler Master's modest rating of 35 cfm seems fairly accurate.
The motor design is exceptionally good, easily one of the best on the market.
