F140P 140mm Static Pressure PWM Case Fan Matte Black RF-P14SF-B2 Features: Seven thick blades are designed for high static pressure so air can be pushed through tight spaces, ideal for mounting on radiators and heatsinks. Minimal gap between blade edges and frame maximizes the spinning area for higher airflow volume and efficiency. Chamfered frame design directs air in a powerful concentrated flow pattern, traveling far into the case to cool vital components. Fluid dynamic bearings provide unwavering stability, low-noise operation, and a 60,000-hour lifespan. PWM control dynamically adjusts fan speed for higher output or lower noise based on system temperatures for efficient cooling. Sturdy frame with rubberized corners absorbs vibrations for low-noise operation, even at high speeds.
