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.
