ID-COOLING AS-140-K Duet

The ID-COOLING AS-140-K Duet is a 140-mm PWM fan designed for case ventilation, air coolers, and radiators when a larger diameter is needed with moderate noise levels. The fan operates in the range of approximately 300–1800 RPM, delivering up to 72.2 CFM of airflow and static pressure up to 1.65 mm H2O, with a maximum noise level rated at 24.9 dB(A). It uses a standard 4-pin PWM connector, allowing the ID-COOLING AS-140-K Duet to integrate easily with most modern motherboards and fan hubs. Equipped with a hydraulic bearing, the fan measures 140 × 140 × 25 mm, weighs approximately 200 g, and operates at 12 V. Based on its overall specifications, the ID-COOLING AS-140-K Duet is best suited for cases with 140-mm mounting positions, where achieving good airflow at lower speeds is a priority compared to 120-mm models. The ID-COOLING AS-140-K Duet is not a purely low-noise solution, but rather a versatile fan for balanced systems that require adequate performance headroom without entering aggressive high-speed territory.
