Phanteks SK PWM Fan, 140mm, Rifle Bearing, Black

This is a 140mm cooling fan designed for integration into standard PC chassis configurations. It features nine optimized fan blades intended to provide a balanced output between significant airflow and necessary static pressure. The unit utilizes a 4-pin connector, enabling Pulse Width Modulation (PWM) control across its operational spectrum. This allows the system to dynamically adjust the rotational speed from a minimum of 500 RPM up to a maximum of 1500 RPM based on current thermal demands.

At maximum output, the fan generates an airflow of 84.5 CFM, paired with a static pressure rating of 1.23 mmH₂O. This capability ensures effective cooling performance for both general case ventilation and installations requiring resistance, such as restrictive dust filters. The fan incorporates a rifle bearing mechanism designed to maintain operational stability and minimize wear over time. This component is rated for a Mean Time to Failure (MTTF) of 40,000 hours, supporting long-term reliability in desktop computing environments. During peak operation, the noise level reaches 36 dB while drawing 0.15 A of current at 12 V.
