Enhance your computer's cooling system with the ARCTIC P12. This 5-pack of PWM PST fans is designed for optimal static pressure, ensuring focused airflow and efficient cooling. The fans operate within a range of 200 to 1800 RPM, regulated via PWM for noise reduction when maximum cooling isn't needed. Utilizing efficient, next-generation PWM IC technology, these fans deliver higher efficiency and energy savings without compromising performance. The advanced motor design contributes to an extended lifespan, with lower motor temperatures roughly doubling the fan's service life. Technical Data: Fan speed: 200–1800 rpm (0 rpm <5 %), Airflow: 56.3 cfm | 95.7 m³/h, Noise Level: 0.3 Sone, Static pressure: 2.2 mmH₂O, Pin: 4-pin. Arctic is known for innovative technologies and fair prices, providing products with an unparalleled price/performance ratio for overclocking and quiet operation.
