Cooler Master Mobius 120/120P PWM/ARGB Review

Introduction to the features of the Cooler Master Mobius 120 PWM/ARGB

The 120 and 140mm diameter fans have become the de facto standard in the PC world, certainly we can find even larger sizes, also smaller, but the truth is that the base of any desktop computer, including the most compact, it is in these two sizes, either to ventilate the case itself as the main cooling elements of liquid cooling kits or more conventional heatsinks.

The evolution of these fans has been varied, from those with very high power for industrial environments such as these Cooler Master Mobius that are in the difficult task of achieving quality performance while being respectful of our ears and at the same time allowing ever greater durability.

This very complex development where such varied expectations have to be met has led to a slow evolution that in the case of Cooler Master has recently gone through the magnificent SickleFlow and now through these Mobius where its axial design stands out where the blades are connected to each other in a mobile frame, a trend that GPU manufacturers have marked in their most advanced designs because it allows more static pressure if designed properly.

We will find the Mobius in sizes of 120 and 140mmwith and without lighting, and with differences in motorization depending on whether they have lighting or not. Our test samples develop 2000rpm on the non-ARGB model and up to 2400rpm on the ARGB model, with substantial differences in flow and static pressure. Today we analyze both variants, in the 120mm model, which is, on the other hand, the most widespread size in all types of PC cooling solutions.

Specifications of the new Cooler Master Mobius 120 PWM ARGB

Almost all fans recently launched on the market seek a difficult balance between noise and rotation speed. The latter is the one that will achieve, to a large extent, that the static pressure and the air flow are high. The blade configuration will have a big impact on this balance and Cooler Master on the Mobius 120 uses a large seven blade configuration. Furthermore, these seven blades are configured in an axial design that improves the pressure generated by the fan.

Among the advantages of the new design we also find a frame that channels the air flow towards the blade system. This limits turbulence around the fan axis. This channeling makes the fan design more efficient and allows Cooler Master to produce one of its most powerful and quietest fans to date. Up to 6dBA quieter than the previous generation.

Cooler Master drives these new fans by its latest generation of motors with “Loop Dynamic Bearing” bearing system that Cooler Master has been producing for at least 10 years. It is a very efficient submerged hydraulic bearing system that gives the fans high durability, exceeding 200,000 hours of average life. It’s the perfect complement to this design as it delivers almost 2500rpm, at least on our sample unit, with less than 40dBA of noise. A spectacular performance that balances very well close to 1800rpm, with noise below 30dBA and surprising performance.

The static pressure of this model reaches 3.6mm-H2O at maximum frequency, with a remarkable pressure also at its most optimal speed, with 2.7mm-H2O of static pressure at 1900rpm. It is one of the best fans we have tested in recent times, although somewhat below the Be Quiet! Silent Wings Pro 4 that we tested a few weeks ago.

The power consumption of this fan is 12A, 1.44W of total consumption, and it has a 5-year direct manufacturer’s warranty. In terms of dimensions, the Cooler Master Mobius 120 is 120mm in diameter with a width of 25mm, weighing 179 grams, the standard for these sizes. The fan includes anti-vibration isolation on each corner of the fan and also includes the appropriate screws for mounting on any box on the market.

PWM and ARGB 2 with integrated cascade connectivity

We have already commented that we can find this model in two variants, with or without lighting, the illuminated model has a support Addressable RGB 2 via a 5v three-pin connector that we can use on any more or less recent controller or motherboard.

The design includes a turning body, from the rotor cover to the blades and their union ring between the blades, made of a light-diffusing material that enhance the effect of the 8 powerful leds placed at the base of the fan rotor. Very dynamic effects and powerful and well-contrasted lighting are achieved with the frame in a matt black color.

Connectivity is independent, with an impeller connected by a PWM-compatible four-pin Molex and lighting with a three-pin ARGB connector that also includes input and output configuration so that we can concatenate more PC lighting elements, whether they are more fans such as this or any other compatible device or accessory.

noise and performance

This fan came to us with different features than we had known in the previous Cooler Master announcement. Develop 20% more maximum frequency, get more static pressure and higher airflow so it has been a very interesting experience. It has a very wide frequency development, from 550 to 2500rpm (they also support complete stop mode 0 rpm and 0 dbA), with a noise that does not exceed 38dBA of noise in any of the cases.

With 5v PWM we can get 550rpm, which makes it profoundly silent in computer idle states. When we push it hard we can reach 2500rpm and almost 80CFM of airflow with a maximum static pressure of 3.6mm-H20 which is quite a figure. Even so, we have been testing its most reasonable balance point and we have found it at a high frequency, no less than 1900rpm, where we almost reached 2.8mm-H2O of static pressure, almost 65CFM of air flow and all this with a noise of just 30dBA that makes it one of the best 120mm fans that have passed through our hands.

Analysis and conclusion

The Cooler Master Mobius It comes in two sizes, 120 and 140mm, and the 120mm model, which we’ve tested in both ARGB and normal variants, is one of Cooler Master’s best fans to date, even bettering their other more recent series. , the SickleFlow we tested also some time ago.

This model is not only more powerful and faster, but it is also quieter, achieving better ventilation performance than its predecessors, it is placed very close to another large fan from another large manufacturer, with differences related to accessories and finishes than to the fan itself. technique. This is a great fan that we can find for a really attractive price.
