Thermaltake TOUGHFAN 14 Black PWM 500 2000rpm controlled high static pressure 140mm Circular Radiator Fan with Anti Vibration Mounting System Cooling, (2 pack) CL F085 PL14BL A

Unparalleled Cooling Performance: The TOUGHFAN is a PWM controlled fan which is designed to perform at a maximum operating speed of up to 2000 RPM allowing unparalleled cooling performance. Exceptional Blade Design: Featuring extreme tensile strength and low thermal expansion coefficient materials, the fan blade is built with special liquid crystal polymer (LCP), a compound which minimizes vibration when the fan is operating at full speed. Metal-Reinforced Motor Hub: The TOUGHFAN’s center is constructed with a full steel motor hub providing enhanced stability and durability. The 2nd Generation Hydraulic Bearing: The 2nd generation hydraulic bearing incorporates a new shaft design with inside etches allowing preservation of lubricant on both sides whilst reducing noise during operation.
