Montech AX140 PWM ARGB Fan, Rifle Bearing, 140mm, Black

This 140mm cooling fan is engineered for effective thermal management within various PC setups, including standard enclosures and liquid cooling radiators. It utilizes Pulse Width Modulation (PWM) functionality, enabling the system to dynamically adjust rotational speeds from 600 RPM up to 1600 RPM based on current thermal requirements. The fan is specified to deliver a maximum airflow of 90.5 CFM (153.76 m³/h) and generates 2.9 mmH₂O of static pressure, indicating capability for use in high-restriction airflow scenarios.

The unit employs a Rifle bearing system, designed for reliable long-term performance and contributing to a rated Mean Time Between Failures (MTBF) of 80,000 hours. Noise generation is limited, registering a peak acoustic output of 27.9 dB at its highest operational speed. Power and speed control are managed through a standard 4-pin PWM connector. Aesthetic requirements are addressed by 24 integrated Addressable RGB LEDs, which connect via a separate 5V 3-pin header compatible with multiple major motherboard synchronization platforms.
