140mm Static Pressure PWM Case Fan NZXT Static Pressure Fans deliver strong airflow in tight spaces, like radiators and heatsinks. With optimized blades, chamfered frame, and fluid dynamic bearings, they offer high-performance, low-noise cooling. High Static Pressure Pressure-optimized blades force air through tight spaces like radiators and heatsinks. Efficient Airflow Minimal blade-to-frame gap maximizes the spinning area for optimal performance. Powerful Cooling Chamfered frame directs air in a concentrated pattern that travels far into the case. Low Noise, Long Lasting Fluid dynamic bearings ensure quiet operation with a 60,000-hour lifespan. Speed Regulation PWM control adjusts speed based on system temperatures for efficient, quiet cooling. Silent & Stable Sturdy frame and rubberized corners absorb vibration noise.
