The Thermaltake TOUGHFAN PWM-controlled high static pressure fan features an optimized structure to maximize high-end cooling needs.Unparalleled Cooling PerformanceThe 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 DesignFeaturing high 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 HubThe TOUGHFANs center is constructed with a full steel motor hub providing enhanced stability and durability.The 2nd Generation Hydraulic BearingThe 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 CoolingThe TOUGHFAN is designed for all cooling applications. Its 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 SystemThe 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.Specification:- P/N: CL-F117-PL12BL-A- Fan Dimension: 120 x 120 x 25 mm- Fan Started Voltage: 9.0 V- Fan Rated Voltage: 12 V- Rated Current: 0.12 A- Power Input: 1.44 W- Fan Speed: 500 2000 R.P.M- Fan Speed With L.N.C PWM : 5001500 R.P.M- Max Static Pressure: 2. 41mm-H2O- Max Air Flow: 58.35 CFM- Noise Level: 22.3 db-a (without L.N.C)- Noise Level: 19.2 db-a (with L.N.C)- Bearing Type: Hydraulic Bearing Gen. 2- Life Expection: 40,000 hrs, 25cConnector: 4 PIN PWM
