Cooler Master MasterFan Pro series is the latest and probably the best arrival in the company portfolio, added with one purpose only and that is to provide a wide range of fans to satisfy every need of a regular user, a gamer or an overclocker. The series itself offer fans with dimensions of 120 mm and 140 mm and four different versions:
To perform this test and review the guys from the marketing team were kind enough to send me MasterFan Pro 120 Air Balance RGB and MasterFan Pro 140 Air Pressure fans, which arrived to me placed inside two pretty big carton boxes entirely in black with front flap covering a see through cut, through which you can see the shape of the propellers. On the front side of the flaps I was able to find pictures of the fans accompanied by the company logo and the model of the products.

By lifting the front flaps I reached a ton of information, explaining all of the specifics for both of the products with additional instructions, graphics and pictures. Of course, the full technical specification is described on the back of the boxes in several languages.
Personally, I really enjoyed the packages but let’s put them aside and proceed with checking the fan structures one by one.
Cooler Master MasterFan Pro 120 Air Balance RGB and Pro 140 Air Pressure STRUCTURE
After I took both of the fans out of their packages for the first time I noticed that even though they are part of the same series they offer an overall similar-looking structure but are totally different in terms of dimensions, propeller structure and overall performance.
So, let’s proceed with checking the fan structures, capabilities and features.
|MasterFan Pro 120 Air Balance RGB front view||MasterFan Pro 140 Air Pressure front view|
Both of the fans are designed with a round, entirely black plastic frame, which unfortunately is pretty thin and a bit flexible. To be installed as a case fan or CPU heat sink cooling unit, 4 rubber corners should be attached via 2 small bolts each. When the corners are attached the fans are with physical dimensions of 120 x 25 mm for the MasterFan Pro 120 Air Balance RGB model and 140 x 25mm for the MasterFan Pro 140 Air Pressure model and offer 4 mounting holes on each side to be used when installing the fans using the screws provided in the package on a 120mm (105 x 105mm screw hole pattern) or 140mm (125 x 125mm screw hole pattern) case fan slot, CPU cooler heat sink or water cooling radiators.
With this I am done describing the only similarity between the two models. Now let’s pay attention to the differences and proceed with checking the propeller structures.
Both of the fans are equipped with totally different propellers inspired by designs of propellers used in modern aircraft engines:
- MasterFan Pro 120 Air Balance RGB is designed and manufactured with completely transparent propeller featuring 9 very sharply angled blades with glossy coating to reduce the air resistance. Each fan blade features a hybrid structure, which draws from both jet engine and helicopter blade designs. The blades are made to propel air farther than the Air Pressure design while still retaining more static pressure than Air Flow models.
- On the other hand, MasterFan Pro 140 Air Pressure offers a propeller with five very wide and very sharply angled semi-transparent blades entirely in grey inspired by helicopters propellers made to move the air less distance but group more force and increase the static pressure into the space behind the fan. Of course, this model also features the glossy coating to reduce the air resistance.

The next major difference between both of the fans is actually located on the back of the frame and is made to provide additional visual or performance options:
Since MasterFan Pro 120 Air Balance RGB is a model made to provide not just performance but also amazing visual options, on the back of the motor there is a small switch delivering the option to choose in what colour the propeller will shine. The fan is designed to offer a Red, Blue or adjustable from entire RGB color spectrum back light colour controlled with the optional CoolerMaster RGB fan controller (it should be bought separately). The interesting thing regarding the back light colour is that the LEDs are located around the stater of the motor just beneath the propeller, which will provide evenly dispersed light through the transparent blades.
On the other hand, the small switch located on the back of MasterFan Pro 140 Air Pressure’s frame is made with totally different purpose. The switch itself is able to change the operation range of the fan and its performance by offering 3 different operational speed profiles, which includes S Mode (Silent), Q Mode (Quiet) and P Mode (Performance).
And here I should point out that the switches located on the back of the fans are really small so something with sharp edge should be used to switch between the visual or the performance modes.
|MasterFan Pro 120 Air Balance RGB cables||MasterFan Pro 140 Air Pressure cables|
And to perform their cooling duties both of the fans are equipped with 4pin PWM powered and regulated bearing featuring jam protection and the Silent Driver IC technology to deliver smoother propeller rotation to reduce the vibrations and the fan clicks. With this bearings the fans are calculated to deliver life expectancy of up to 490,000 hrs.
In addition, the MasterFan Pro 120 Air Balance RGB model is supplied with a second cable, which should be used when the fan is paired with other fans and working together with the CoolerMaster RGB fan controller.
With these motors installed, the fans are able to deliver:
- MasterFan Pro 120 Air Balance RGB is working at 650 ~ 1300 ± 10% revolutions per minute range with maximum airflow of 42.7 ± 10% CFM, maximum static pressure level of 0.96 ± 10% mmH2O at noise level range of 6 ~ 20 dBA.
- MasterFan Pro 140 Air Pressure is capable to deliver 3 different operational modes:
- S Mode (Silent) – the fan is working at 650-1,550 ± 10% revolutions per minute range with maximum airflow level of 46.2 ± 10% CFM, static pressure level of 1.59 mmH2O ± 10% at noise level range of 6 – 20 dBA.
- Q Mode (Quiet) – the fan is working at 650-2,200 ± 10% revolutions per minute range with maximum airflow level of 64.2 ± 10% CFM, static pressure level of 3.15 mmH2O ± 10% at noise level range of 6 – 30 dBA.
- P Mode (Performance) – the fan is working at 650-2,800 ± 10% revolutions per minute range with maximum airflow level of 82.2 ± 10% CFM, static pressure level of 5.28 mmH2O ± 10% at noise level range of 6 – 36 dBA.
Cooler Master MasterFan Pro 120 Air Balance RGB and Pro 140 Air Pressure ADDITIONAL ACCESSORIES
|MasterFan Pro 120 Air Balance RGB accessories||MasterFan Pro 140 Air Pressure accessories|
Since both fans are part of the same series they arrived with absolutely identical accessories packs, which includes only one set of 4 metal black installation screws to attach the fans to the case fan slot.
Since I am done with checking the fans and their accessories packs I believe it is time to check their actual performance.
Cooler Master MasterFan Pro 120 Air Balance RGB and Pro 140 Air Pressure TESTS
The tests will be conducted in my standard way. I will install the fans and test them at 5V/7V/9V/12V and my goal will be to check the performance of the products in real conditions. They will be tested under close-to-perfect conditions, not taking into account any external factors. The results achieved during the test can in no way be the same if the models are mounted on a cooler or on the case fan slot of any modern computer case. I will measure the amount of air going through the fans for one hour and their speed. For this I use a fan controller, a voltage meter, an anemometer and a stand made specifically for this purpose.
And this is what the fans look like installed on my test stand:
The test results are shown in the following charts:
Airflow through the fans at 5V, 7V, 9V, 12V
Propellers rpm during the tests at 5V, 7V, 9V, 12V.
The anemometer showed the following air speed passing through the propellers:
After mounting the fans onto the stand, and leaving them to rotate for about 60 minutes at maximum speed, it was time for the tests to begin.
As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and both of the fans made at least one stable revolution at about 5V.
Test at 5V:
At the first test, conducted at exactly 5V , MasterFan Pro 120 Air Balance RGB was rotating at stable 510 revolutions per minute, providing airflow level of 26.88 cubic metres per hour, while MasterFan Pro 140 Air Pressure was providing airflow level of 57.12 cubic metres per hour at only 1290 revolutions per minute. At this test the first model was dead quiet, while the second fan was generating a tiny noise coming out of the air passing through the propeller.
Test at 7V:
At the second test, performed at exactly 7V, MasterFan Pro 120 Air Balance RGB was rotating at 750 revolutions per minute, providing airflow level of 41.28 cubic metres per hour, while the bigger brother in the series was rotating at 1965 revolutions per minute with airflow level of 86.88 cubic metres per hour. At this test the 120mm fan was still quiet, while the big brother was pretty noisy.
Test at 9V:
At the third test conducted at 9V, the smaller version in the series was providing airflow level of 58.56 cubic metres per hour while rotating at 990 revolutions per minute, while for the MasterFan Pro 140 Air Pressure fan the airflow level was 113.28 cubic metres per hour, while rotating at 2445 revolutions per minute. At the third test the first model remained quiet, while the second fan was really loud.
Test at 12V:
At the last test conducted at exactly 12V, both fans delivered their maximum performance, which for MasterFan Pro 120 Air Balance RGB was airflow level of 71.52 cubic metres per hour at 1410 revolutions per minute, while for MasterFan Pro 140 Air Pressure it was 142.08 cubic metres per hour, while rotating at 2880 revolutions per minute. At this test the 120mm fan was generating a tiny noise coming out of the air passing through the propeller, while the 140mm fan was roaring like a beast.
Cooler Master MasterFan Pro 120 Air Balance RGB and Pro 140 Air Pressure CONCLUSIONS
1. Cooler Master MasterFan Pro 120 Air Balance RGB and Pro 140 Air Pressure Performance:
Cooler Master MasterFan Pro 120 Air Balance RGB and Pro 140 Air Pressure Performance are two fans, which I find very attractive and very reliable and in which I invested a lot of time to complete this test and review. All those hours are totally worth it, since I was able to see really interesting fan structures, great cooling performance and amazing additional features.
Cooler Master MasterFan Pro 120 Air Balance RGB is a fan definitely made to deliver the best possible balance between airflow/static pressure/noise level, packed as a structure with additional feature, which in real life just looks great. The product itself delivers airflow, which is more than enough so the fan can be installed on a 120mm case fan slot to boost the overall airflow inside every modern case or as a main cooling unit for CPU heat sinks compatible with 120mm fans. Together with a decent heat sink the fan will be able to keep every low or middle grade Intel or AMD processor working at default or a bit overclocked frequencies.
Through the first 3 tests this model was working absolutely quiet. Just the last test at 12V made the fan generate a tiny noise coming from the air passing through the propeller.
On the other hand, the MasterFan Pro 140 Air Pressure Performance is the beast in the series designed with one purpose only and that is provide brutal airflow and static pressure to cool every heat sink or water cooling radiator compatible with 140mm fans, which will keep high grade processors working with full load at high or extremely high overclocked frequencies.
Regarding the noise, the fan is extremely loud and it is not suitable for silence seeking users. But after all with this cooling performance, it is pretty normal to have such a high noise level.
In addition, the three predefined working profiles, which could be changed with the help of the small switch on the back of the fan, will deliver wider range of possibilities, not just for the enthusiasts but also for the regular users.
2. Cooler Master MasterFan Pro 120 Air Balance RGB and Pro 140 Air Pressure Appearance:
Apart from the very serious cooling capabilities, both of the models part of the MasterFan series offer pretty attractive and at the same time very aggressive appearance.
By default MasterFan Pro 120 Air Balance RGB is designed as a structure of black frame and transparent propeller featuring very stable and well dispersed red or blue back light colours but the full magic will be available only with CoolerMaster RGB fan controller, which should be bought separately and will reveal colours from the entire RGB color spectrum.
On the other hand, MasterFan Pro 140 Air Pressure is definitely the fan with simpler and much more stylish appearance with its black and semi-transparent grey propeller.
In addition I believe that Pro 120 Air Balance RGB will look really amazing installed as a case fan and powered by the RGB fan controller, while Pro 140 Air Pressure’s place is installed on a CPU heat sink or water cooling radiator.
I think Cooler Master MasterFan Pro 120 Air Balance RGB deserves:
