In the second part of our massive 120mm fan roundup we will cover 27 models from 15 companies from all around the world. These fans have a rated speed of over 1350 RPM, sometimes much higher. We will discuss quiet entry-level products as well as high-speed monsters that can blow everything out of the way. Let's now have a look at each of the fans in alphabetical order.

Teschnical Specifications

The technical specifications of all testing participants are summed up in the following table:

Testing Participants

Cooler Master Turbine Master MACH1.8 (R4-TMBB-18FK-R0)

The Cooler Master Turbine Master MACH1.8 comes in a blister wrap with a paper insert inside.

 

The fan’s specs and key features are listed on the back of the insert. In the top part of the packaging there is a plastic cap for the fan’s motor, four silicone pins, a PATA power adapter, silicone spacers and four self-tipping screws.

The fan is manufactured in China, costs $16 and has a 1-year warranty. At only 110 grams, the Turbine Master MACH1.8 looks unusual with its semi-frameless impeller that has as many as 16 blades.

 

With the impeller and frame shaped like that, the fan should have some advantage in terms of air flow compared to classic 120mm fans as it can take additional air in from the sides of the blades. Cooler Master talks about that in the next slide:

With as many as 16 blades, the impeller allows Cooler Master to claim an air flow of 80.3 CFM at a speed of 1800 RPM (compare this, for example, to 62.7 CFM at 2350 RPM specified by Corsair for its 120mm fan).

That said, the diameter of this fan’s impeller is only 111 mm while its motor is 40 mm in diameter. The static pressure is specified to be 1.96 mm of water. The noise level is 30.5 dBA.

The key electrical specs are indicated on its sticker:

The fan’s barometric ball bearing has a specified service life of 100,000 hours (or over 10 years of continuous operation). The impeller can be easily taken off for cleaning or a look at the fan’s motor:

  

The Turbine Master MACH1.8 has rather high power requirements for a fan of its class: 0.5 amperes and 4.6 watts. According to our measurements, it consumes no more than 3.4 watts, but that's quite high anyway. The 3-wire cable is about half a meter long.
