Cooler Master has completely revamped their fan series to fit their new “Master” rebranding of their products and design philosophy, and we took at look at the first new fan that came from this- the MasterFan Pro 120 Air Pressure– before, and it was a mostly positive experience. That fan was based off an existing fan design already, the Silencio FP, but had some changes done to the frame and rotor as well as adding in a switch to toggle between max fan speed allowing for flexibility of operation for customers around the world who may prioritize noise or performance or both balanced. That was their solution for radiators, but Cooler Master thinks their MasterFan Pro Air Balance (I will call it CM MasterFan Pro AB for short) can also do a good job, and so I have a sample here for review. Let’s see how it works out!

At this point, the fans are not up on Cooler Master USA and so let’s take a look at the specs from the product page on Cooler Master Eu website:

Cooler Master provides a decent set of specifications here, and there is also a data sheet for those interested. This is not an LED fan, and neither are any of the other 4 MasterFan fans out so far. This is also a standard 25 mm thick square frame 120 x 120 mm fan, and is intended as a balance between static pressure and airflow with a higher airflow rating than the MasterFan Pro Air Pressure but a lower static pressure rating. A jack of all trades then? Time will tell. The most interesting feature, perhaps, is that the fan has 3 modes which affect the max speed. S (Silent) mode has the fan with an RPM range of 650 to 1300 (+/- 10%), Q (Quiet) mode from 650 to 2000 RPM, and P (Performance) mode from 650 to 2500 RPM. One could argue that Cooler Master is giving you 3 fans for the cost of one, if you were indeed looking for different rated speed versions of the same fan, but we will see for ourselves how it works out in practice. This uses their POM (polyoxymethylene) bearing which they have used in fans for 2+ years now and is a sealed, FDB style bearing. Cooler Master is quite proud of it and rates it with a life expectancy of close to 500, 000 hours which is more than I have seen anyone else report. But then they go and give this a 2 year warranty thus negating everything and I would really encourage them to increase said warranty to 5 years given they seem to be so confident of the fan.

Let’s take a good look at the fan now on the next page.
