The ARCTIC P8 PWM PST case fan enhances airflow in your computer system, ensuring optimal cooling performance. With a fan diameter of 80 mm, it achieves an air flow of 23.4 cfm while maintaining a noise level of just 0.3 Sone for quiet operation. Fluid dynamic bearing technology enhances longevity and reduces friction for reliable performance over time. This case fan operates under a range of environmental temperatures, from 0°C to a maximum of 40°C, making it suitable for various setups. With PWM PST control, the fan speed adjusts according to the thermal demands of your system, allowing for efficient cooling without unnecessary noise. The robust construction and compliance with international standards underscore its quality and dependability.
