The Mobius 120 OC is the flagship fan of the line, utilizing double ball bearings for increased lifetime and high airflow, thanks to the maximum speed of 3200 RPM. Cooler Master is so confident of this product, that backs it up with a lifetime warranty!
I continue hitting hard on the fan reviews to justify the huge bucks I paid for the Longwin machine. In this episode, I will show you the Cooler Master Mobius 120 OC. This is the only fan I have evaluated featuring a lifetime warranty! The warranty applies to the original buyer, and it is not transferable. Still, it is impressive, to say the least.
The Mobius 120 OC uses interconnecting fan blades, called ring blade design, which according to CM, eliminate vibrations, leading to a more stable operation. There is also a fan speed toggle through which you can set the fan speed to three levels: low, mid, and high. Moreover, the motor hub is made of metal for increased performance and enhanced durability.
On Amazon, the Cooler Master Mobius 120 OC costs $35, making it even more expensive than the Phanteks T30-120. Given the lifetime warranty, I can understand the price difference.
