Cooler Master has launched a new lineup of performance optimized fans called Mobius featuring both non-RGB and ARGB flavors in a 120 mm form factor. Cooler Master has employed a new architecture it is calling Ring Blade Design, that connects all the fan blades together. This reportedly improves airflow, while eliminating unwanted vibrations at the same time.
The company says the fans are available today, but didn't make pricing immediately available.
Cooler Master is releasing two 120 mm variants right now, in both a standard and an ARGB version, called the Mobius 120 and the 120P ARGB. The Mobius 120 will feature a fully blacked out look with a black shroud and even dark fan. The RGB variant will feature ARGB lighting with frosted fan blades to increase the lighting dispersion.
Despite the lighting differences, the ARGB model is a higher performing on paper compared to the Mobius 120, as well. The ARGB model features a maximum speed of 2400 RPM and a maximum noise level of 30 dBA, with a CFM rating of 75.2. The non-ARGB model on the other hand features a lower fan speed of 2050RPM and a maximum air flow rating of 63.1 CFM. But thanks to the lower fan speed, the noise level is significantly reduced to 22.6 dBA.
Both fans are rated for up to 200,000 hours of use, and require 4-pin PWM output to function. The ARGB variant will require an additional 3-pin ARGB header to be present as well for lighting functionality.
The Mobius series of fans are reportedly very stable under load in a number of different orientations. The fans use a new Ring Blade Design that connects all the fan blades together at the tips with a ring, which can reduce unwanted air turbulence that can vibrate the spinning blades.
For even more stability, Cooler Master has employed the use of dynamic loop bearings as well, which keeps the bearings better lubricated compared to more traditional methods. This in turn, improves the reliability of the bearings and improves fan stability. Cooler Master has also added a magnetic ring to the bearing shaft to prevent the fan from tilting in unorthodox orientations (such as 45 degree angles).
All these factors combined have allowed Cooler Master to tune the Mobius fans to a 6dBA noise level or lower, without compromising performance. These fans are designed to function both as chassis fans and static pressure fans for CPU coolers, hard drive cooling and radiators.
