HIGH STATIC PRESSURE: Efficient even under resistance the generated airflow easily penetrates dense radiators, narrow perforated panels, and mesh structures, ensuring reliable cooling. PWM CONTROL WITH A WIDE SPEED RANGE: The speed can be continuously adjusted up to 2500 rpm via a 4-pin PWM connector. The fan stops completely at speeds below 5%. PRECISE MANUFACTURING FOR MAXIMUM SMOOTH RUNNING: Minimal gaps, automatic balancing, and high-precision measurement noticeably reduce vibrations for quiet, efficient, and long-lasting performance. SMOOTH-RUNNING FLUID DYNAMIC BEARING (FDB): The self-lubricating bearing minimizes noise during operation ideal for quiet, efficient cooling and a long, reliable service life NEW FAN BLADE DESIGN FOR MORE PERFORMANCE: The redesigned rotor blades offer an optimal balance of performance and low noise especially efficient at low speeds
