Thermaltake TOUGHFAN 14 White PWM-controlled high static pressure fan features an optimized structure to maximize high-end cooling needs and fulfill users' wishes to add the color white to the series. TOUGHFAN Series White | Powerful and Noiseless TOUGHFAN 14 White high static pressure fan can perform at a maximum operating speed of up to 2000 RPM, producing a consistent airflow of 119.1 CFM with 3.54 mm-H2O static pressure, and maintaining a low audio noise level of 33.2 dB-A. 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 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. Lowering audible levels and extending lifespan. 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.
