Thermaltake TOUGHFAN Turbo is a PWM controlled high static pressure fan with a maximum operating speed of up to 2500 RPM, fulfilling users high-end cooling needs. Superb Cooling Performance at 2500 RPM TOUGHFAN Turbo is a PWM controlled fan with a maximum operating speed of up to 2500 RPM, bringing our users the ultimate cooling experience. Exceptional Grey Fan Blades Featuring high tensile strength and low thermal expansion coefficient material, the THOUGHFAN Turbo is designed with grey colored liquid crystal polymer (LCP) made fan blades, minimizing vibration when the fan operates at full speed. Metal-Reinforced Motor Hub The TOUGHFANs center is constructed with a full steel motor hub providing enhanced stability and durability. 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. High Air Pressure and High Airflow TOUGHFAN Series is designed to produce high static pressure and airflow, providing users impeccable cooling results. TOUGHFAN 12 Turbo 72.69 CFM/ 5002500 R.P.M/ 3.78 mm-H2O 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.
