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 high tensile strength & low thermal expansion coefficient materials, the fan blade is built with special liquid crystal polymer (LCP), a compound which minimises vibration when the fan is operating at full speed. Metal-Reinforced Motor Hub The TOUGHFAN’s centre is constructed with a full steel motor hub providing enhanced stability & 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. Lowering audible levels & extending lifespan. Built for Superior Cooling The TOUGHFAN is designed for all cooling applications. It’s your perfect go to solution whether your using it as radiator fan or on a air cooler. Level up with the TOUGHFAN for superior cooling performance. Anti-Vibration Mounting System The in-mold injection anti-vibration rubber pads dampen the vibration of the fan allowing the fan to spin at higher levels without compromising noise levels. The fan is designed with 80% coverage for all corners, maintaining low noise levels when in operation. Features 120mm. Hydraulic Bearing Gen. 2. 500 ~ 2000 R.P.M.
