Taking a look at both the Cooler Master Mobius 120P ARGB and Mobius 120, we have what appears to be an ARGB fan and a regular fan. On the left, we have the Mobius 120P ARGB and to its right the Mobius 120. Aside from the translucent blades on the Mobius 120P ARGB, the rest of the frame is black, as with most fans. The Mobius 120 is the exact same with some very dark blue blades instead. Despite being like many other fans, Cooler Master decided against placing their logo on the center of the impeller. Around the mounting holes for both fans, there are nice large pads on both sides to help dampen any vibration, allowing you to mount them in either direction. Both fans have a regular thickness of 25mm.
Internally, the Cooler Master Mobius 120P ARGB and Mobius 120 use loop dynamic bearings. These bearings are similar to regular fluid bearings, but have a system Cooler Master calls Oil Reflow to help the oil flow continuously and keep the lubrication more constant. This achieves an increased life span and keeps the noise levels low. Cooler Master also implements an Anti-Sway System, which uses a magnetic ring to prevent the bearing shaft from tilting, allowing you to mount the fan in any orientation you desire. While I cannot confirm the lifespan, you should not be worried as these loop dynamic bearings are rated for 200,000 hours. In addition, Cooler Master does provide a 5-year warranty for both models, so I am not too concerned for its longevity. We will see how much noise the Mobius 120P ARGB and Mobius 120 output when we test them later on in this review.
Taking a closer look at the blades of both fans, you can see many similarities as they share the same general design. The blades of the fans are connected to an outer rim that Cooler Master calls the Ring Blade Design. This design is to reinforce the fan and eliminate vibration. There is a gap in between each of the fins with no overlapping blades. The angle each blade sits in comparison to the rotating middle is about 30 degrees. The curvature of the blades is about average. There is a total of seven blades on the impeller. The blades of both the Cooler Master Mobius 120P ARGB and Mobius 120 are all quite smooth.
On the output side for both fans, four arms are attached to the frame with a straight arm seen in the image above. These arms will obstruct minimal amounts of air passing through. The Mobius 120P ARGB has two cables attached to the fan for power, control, and RGB lighting. The power and control cable is a 4-pin PWM controlled header and the ARGB cable is a 3-pin ARGB header. It is important to mention that the ARGB cable can be daisy chained to allow for more ARGB connections. On the Mobius 120, there is a single cable attached for power and control. All of the aforementioned cables are approximately 300mm. This should be long enough to maneuver around most cases, but it will be quite tight. I could see the potential in not being able to properly route cables in a larger case. In future iterations, I would greatly appreciate a longer cord, as I found my general testing process was quite difficult with this length. The cables are quite flexible, and they are braided. A braided cable is very desirable as it enhances its durability.
Looking at the specifications of the Cooler Master Mobius 120P ARGB, we have a maximum CFM or cubic feet per minute rating of 75.2 CFM. The Mobius 120 is slightly lower at 63.1 CFM. These values are quite high for a 120mm fan. In terms of static pressure, the Mobius 120P ARGB specifies about 3.63 mmH2O maximum, while the Mobius 120 is listed at 2.69 mmH2O. Note that these values are achieved by the fan spinning at their maximum speed, which is 2400 RPM for the Mobius 120P ARGB and 2050 RPM for the Mobius 120. As for noise, the specifications lists it in units of dBA. The Mobius 120P ARGB and Mobius 120 have a rated noise level of 30 dBA and 22.6 dBA, respectively. As both the Mobius 120P ARGB and Mobius 120 are able to scale down to 0 RPM, it is possible to achieve 0 dBA.
Only the Cooler Master Mobius 120P ARGB feature RGB LED lighting, as its name suggests. The setup process is quite straightforward. Simply plug in the 4-pin PWM and 3-pin ARGB headers into the correct spots on your motherboard. If you are looking to be using a proprietary software to control the ARGB lighting, you will need Cooler Master’s Control Box, which I do not have on hand. The Control Box allows the use of the MasterPlus+ software. In my use, I will be using motherboard software to control the fans. When turned on, the fan looks quite nice, although typical. There is not much more a fan can do to look better, haha.
