Designed with precision Carefully designed and tested to increase static pressure and concentrate airflow to achieve exceptional cooling performance in any assembly application, including the configuration of cooling radiators, radiators and housing fans. The narrow frame and wide fan blade provide a larger surface area to ensure higher performance. Elite Cooling Extremely efficient with the range of PWM up to 1850 rpm, which maximizes air pressure and air flow, providing impressive cooling results while offering a dynamic balance between high performance and quiet work. Super quiet The extremely silent FK120 fan, with a maximum capacity of only 28 dBA at full load, is specially designed for silent noise. The dynamic fluid bearing provides excellent performance and reliable long-term stability. Exceptional details High-quality butylene terephthalate (PBT) has been used to ensure increased durability and wear resistance, so fan blades retain high tensile strength. The absorbing rubber pads cover screw mounts to reduce unnecessary vibrations and ensure stable operation.
