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 and 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 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. Lowering audible levels and 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.
