Description

The Cooler Master MasterFan M140 ARGB represents a significant leap in cooling engineering, blending industrial-grade materials with refined acoustics. By utilizing a full aluminum frame and LCP (Liquid Crystal Polymer) fan blades, this unit minimizes vibration and blade deformation at high RPMs, ensuring consistent airflow for demanding hardware configurations.


- Enthusiasts building high-end workstations who prioritize long-term component reliability.
- PC gamers seeking a silent cooling solution that does not compromise on thermal headroom.
- Modders looking for a premium aesthetic with integrated, subtle ARGB Gen.2 lighting.
- Users upgrading from standard plastic fans to reduce system noise floor.
- System builders requiring a durable fan with a high MTBF for 24/7 operation.

- Dimensions: 140 x 140 x 30mm
- Speed: 0–1600 RPM
- Airflow: 81 CFM
- Static Pressure: 2.39 mmH₂O
- Noise Level: 25.9 dBA
- Bearing: Magnetic Levitation
- Connector: 7-Pin PWM
- Warranty: 5 Years

In practice, the M140 feels exceptionally sturdy due to its aluminum construction. The magnetic levitation bearing eliminates the friction typical of sleeve or rifle bearings, resulting in a smooth, low-frequency sound profile even when the fan ramps up to its maximum 1600 RPM. The 30mm thickness provides a slight advantage in static pressure compared to standard 25mm fans, making it effective for both case intake and radiator mounting.

Compared to standard plastic-framed fans, the MasterFan M140 offers superior structural rigidity and vibration dampening. While traditional fans may exhibit resonance at specific speeds, the aluminum frame acts as a heat sink and stabilizer, keeping the acoustic signature significantly lower than competitors in the same airflow class. It serves as a direct upgrade for users who find standard case fans too loud or flimsy.

- Does the M140 support standard motherboard ARGB headers? Yes, it uses ARGB Gen.2 technology compatible with most standard 5V 3-pin headers.
- Is the 7-pin connector compatible with standard PWM headers? The fan includes an integrated controller/adapter system to ensure compatibility with standard PWM motherboard headers.
- How does the 30mm thickness affect case compatibility? While slightly thicker than the standard 25mm, it fits most modern ATX cases, though users should verify clearance in compact ITX builds.
- What is the benefit of the LCP material? LCP allows for tighter tolerances between the fan blade and the frame, which increases airflow efficiency and reduces turbulence.
- Is the 5-year warranty standard for this class? Yes, the 5-year warranty reflects the high MTBF of over 200,000 hours provided by the magnetic levitation bearing.
