LENOVO Ventoinha de arrefecimento da CPU DC5V 40x40x10mm 4-Pin PWM

The LENOVO DC5V CPU cooling fan is a high-performance, compact cooling solution designed for efficient heat dissipation in tight spaces. With a 40x40x10 mm form factor and 4-pin PWM connector, this fan offers precise speed control and reliable operation for CPUs and other components requiring active cooling.

Advantages

Equipped with SSO2 bearing technology, this fan delivers exceptional longevity with a Mean Time To Failure (MTTF) exceeding 150,000 hours. The PWM control allows for dynamic speed adjustment from 1100 RPM to 5000 RPM, balancing noise and cooling performance. At maximum speed, it generates only 17.9 dBA noise while providing 8.2 m³/h airflow and 1.78 mm H2O static pressure.
