Chieftec ZF-1425PWM PWM Fan, Hydraulic Bearing, 140mm, Black

This 140mm PC cooling fan is engineered specifically for effective chassis ventilation, ensuring continuous thermal management within a computer system. Integration of Pulse Width Modulation (PWM) functionality allows the rotational speed to be dynamically controlled via a 4-pin header, enabling precise performance adjustments. The fan operates across a wide speed range, starting at 0 RPM and reaching a maximum rotational speed of 1200 RPM. This operational profile generates a maximum airflow of 56.4 CFM and a static pressure reading of 0.83 mmH2O.

Reliable operation is maintained through the utilization of a hydraulic bearing system, designed for consistent long-term performance and durability. At maximum operational speed, the unit produces a maximum noise level measured at 20.1 dB. The fan adheres to a standard 140 x 25 mm form factor, constructed primarily from plastic materials for the enclosure and blades.

Power requirements necessitate a 12V DC input, drawing 0.38 A and consuming 4.56 W under typical load. The fan weighs 165 grams and includes necessary mounting hardware, facilitating immediate installation into compatible chassis locations. This product maintains compliance with multiple international standards, including CE, RoHS, WEEE, and EAC.
