ship from Japan^^FN1542 Japanese product 1 year^^PWM speed regulation allows speed adjustment within the range of 500-2500RPM^^For bearings, a reinforced metal motor hub that enhances stability and durability, and second-generation hydraulic bearings that reduce operating noise with lubrication and are excellent in quietness and durability are adopted. ^^The biggest feature is the fan blade that uses a special liquid crystal polymer material with excellent tensile strength and coefficient of thermal expansion. ^^The shape does not change even at high speed rotation, the gap with the fan frame is minimized, and the structure prevents thermal expansion, so it is effective for radiator cooling.
