Cooler Master Mobius 120P


The new Mobius 120 Fan from Cooler Master had a pretty respectable noise-to-performance ratio. The Mobius 120P is trying to take that ratio, and push it further and beyond by increasing the max fan speed significantly! Let's take a closer look at the performance version of Cooler Master's Mobius Fan!




  • Good Noise-to-Performance Ratio
  • Good Max-Performance Quality
  • Excellent Build Quality
  • Fabric-sleeved PWM Cable


  • The RGB implementation can be irritating if the fan is pointing away from you


  • The Cable should be longer



What's in the Box?



Cooler Masters Performance Mobius 120P fan comes in pretty much the exact same packaging as the slower Mobius 120. Once everything is removed from the box we will be left with the following items:

  • Mobius 120P Fan
  • 4x Fan Screws
  • 1x Cooler Master ARGB connection piece

Down below you will also find a summary of the Fan's specs:

Name Cooler Master Mobius 120P
Size 120x120x25mm
Speed 2400RPM
Airflow 75.2CFM
Static Pressure 3.63mm/H2O
Noise <30dbA

PWM for Speed

3-pin ARGB for RGB

Cable Length 30cm
Bearing Loop Dynamic Bearing
Motor 4-Pole
RGB RGB illuminating the center of the fan


Installing the fan itself is the usual process. Position the fan where it is supposed to be installed, screw in the fans, that's it.




From there, we need to connect the Fan's PWM cable. Similarly to the slower Mobius 120, the cable is nicely sleeved using a fabric material. Unfortunately, the cable is just as short as it was for the other fan. Being only 30cm long doesn't seem like a well-chosen length for us.




As the Performance version of Cooler Master's Mobius series comes with ARGB, we also need to connect the 3-pin ARGB cable. In addition to the 3-pin ARGB connector at the end of the cable, Cooler Master also added a splitter allowing us to daisy-chain multiple fans or devices using the same header on the motherboard. Thankfully, Cooler Master also includes one of their ARGB connection holders. 

Although it might look like a gimmick, this little piece of plastic is incredibly helpful to keep daisy-chained ARGB Cables connected. Something that we are incredibly grateful for considering how quickly these cables tend to disconnect.


Similarly to the regular-speed Mobius 120, the Mobius 120P's frame comes in an all-black color and is built incredibly stiff thanks to its numerous reinforcements. Also similarly to the other fan, a Mobius 120P comes with rubberized corner pieces on each side, however, in this case, they are all-black too.




The last part which is shared with the Mobius 120 is the 7 heavily bent wings design using a Ring Blade all around them. This circle not only helps to stabilize the fan wing during very quick rotations, but it also helps direct the pushed air into a specific direction, diminishing any "spread effect" if it is unwanted. Due to this diminished spread effect, we already saw other fans perform slightly better when used as an intake or exhaust case fan, thanks to the air going exactly where we plan it to go.




From here on, most of the Fan is looking relatively different due to the implemented ARGB.

The Fan wings come in a milky- semi-seethrough material that allows the ARGB to spread all across the fan.

Inside the central part of the fan, there are some hidden LEDs that are pushing the light out.




Although the chosen LEDs are strong enough to make the complete fan shine in unicorn dust power, we are not particularly happy with this implementation. The LEDs in the center are positioned at a 90° angle to the board they are attached to. The idea behind the was probably to create a sort of backdrop- color behind the fan. However, this has the huge side effect that the LEDs are visible at the right angle from the back. 

Installing the fan in the front of a case with the case being pointed away from you might therefore lead to you seeing the LEDs all the time. And seeing LEDs usually means being blinded by them.




Therefore, we believe this was a poor design choice and Cooler Master should have stuck to the decade-old approach which might require stronger LEDs but doesn't blind its user.



We benchmarked Cooler Master's Mobius 120P using our usual Case Fan setup.




Letting the fan spin at its max 2400RPM allowed the CPU to drop to 44.6°C. This positions the Mobius 120P in the upper third of our benchmark chart and a full 6°C in front of the slower spinning models.




Over on the Noise-to-Performance graph, we were able to see that the Performance edition kept the exact same Noise-to-Performance ratio while being able to prolong its journey a bit longer making it a very good "quiet" case fan with a hidden potential for performance bursts.


As we were already quite happy with Cooler Master's Mobius 120 Fan, it is just natural that we are just as happy with the performance version.




Not only did Cooler Master manage to the positive aspects of this fan and pair it with an additional performance burst, but they also included some handy goodies such as their ARGB connection piece.


The only aspect of the fan that we did not particularly enjoy is the orientation of the LEDs. Hopefully Cooler Master is able to correct this in future batches of this fan.




All in all, just like we did for the Mobius 120, we can absolutely recommend the Mobius 120P thanks to the relatively good Noise-to-Performance ratio. And if ARGB is not something that puts your off, or if it is something you desire, we would always recommend going for the performance version as the additional performance boost might not be something you need, but it is definitely a good thing to have it.
