Cooler Master also advertises compatibility with Asus Aura Sync, ASRock RGB LED, Gigabyte RGB Fusion and MSI Mystic Light Sync. The 4-pin RGB connection makes it possible to operate the fans on “external” RGB controllers.

In the side view you can see it even more clearly. This design, however, leads to the fact that the specified depth of 25mm is no longer quite right: we measure 28mm. If we were still wondering why “only” fan screws are included in the scope of delivery, as many other manufacturers still supply rubber coupler, we now recognize that the Cooler Master RGB fans always have their decoupling. They also have a kind of spacer on one side.

They are each fastened with two Allen screws, which looks very high quality. The corners of the fans are made of rubber which is to be used for vibration damping. The connection cable has more lines than “normal” fans, since the fans have a 4-pin RGB connection in addition to a 4-pin PWM connection. The fans can also glow red or blue without RGB controller. In addition to “RGB” for operation with the RGB controller, “R” and “B” can be selected.

On the back, the fans have a small switch.

Depending on the model, the fan blades are differently shaped, here again Air Flow (left) and Air Balance (right) in comparison: With their transparent, milky fan blades, they ensure good refraction besides, you can see the copper coils inside.
