• Automatic speed control via the 4-pin PWM fan cable interface, adjusting the speed according to the motherboard temperature, with a maximum speed of 1500 RPM. • Fan dimensions: 140 x 140 x 25 mm. Speed: 1500 RPM ± 10%. Noise: ≤27.6 dBA. Current: 0.15 A. Air pressure: 2.35 mm H2O (max). Airflow: 82.5 CFM. • High precision S-FDB V2 bearings, sealed construction, providing long life and improving cooling performance while keeping noise to a minimum. • Perfect combination: suitable for both computer case use and with a CPU cooler, eliminating generated heat and allowing for maximum cooling. Ideal for cases, radiators, and CPU coolers. • Process improvement: the fan blades are initially balanced and then corrected again using a laser balancing machine with three adhesive points to address potential imbalances in fan rotation, improving its performance.
