DESIGNED WITH PRECISIONCarefully constructed and tested to enhance static pressure and concentrate airflow for outstanding cooling performance on any mounting application including cooler heat sinks, radiators, and case fan configurations. The narrow frame bezel and wide fan blade provides increased surface area to deliver higher efficiency.ELITE COOLINGExtremely efficient with a PWM range up to 1850RPM that maximizes air pressure and airflow for impressive cooling results while offering dynamic balance between high performance and low-noise operation.SUPER SILENTMaxing out at just 28dbA under full load, the extremely silent FK120 fan is exceptionally designed for quiet noise levels. The fluid dynamic bearing provides superior performance and reliable long-term stability.OUTSTANDING DETAILSHigh-quality polybutylene terephthalate (PBT) material is used to ensure increased durability and wear resistance, allowing the fan blades to maintain high tensile strength. Shock-absorbing rubber pads shield the screw mounts to reduce unnecessary vibrations for stable operation.
