LN SERIES OPTIMIZED FOR SILENT ENTHUSIASTS: With a 4502000 rpm speed range, the fan is tuned for a balanced ratio of performance and low noise, avoiding extreme peak values and ensuring quiet operation ^^ PWM CONTROL WITH WIDE SPEED RANGE: The speed can be progressively adjusted up to 2000 rpm via the 4-pin PWM connection the fan stops completely at less than 5% PWM ^^ 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
