OTTO SC12Ultra premium 120mm water resistant heatsink and radiator cooling fan, featuring advanced structure design derived from the automobile industry. IP68-rated rotor technology that delivers the ultimate balance between ultra-performance and silence. Rubber mounting pins included.Elite Pressure Optimised Cooling Fan- Advanced auto industry structure design- IP68 rated rotor technology- Advanced blade technology for hi-static pressure- Intelligent PWM speed control- Easy to clean- Rubber mounting pins- Three-phase motor 4 poles, 6 slots- 4-5% head dissipation efficiency- Patented anti-vibration structure- Extended fan lifeAdvanced Blade DesignAdvanced sickle-flow design provides focused hi-static pressure, releasing strong and concentrated streams of air, making it perfect for heatsinks and radiators. As well as heavy duty applications.Perfectly Fine-Tuned P-Q CurveOtto SC12 has been carefully fine-tuned for optimising static pressure in the intersection relative to the radiator and heatsink applications in order to maximise the overall performance of the fan.Advanced Auto Industry Structure DesignPatented spring-like anti-vibration structure ensures minimum vibration noise output. Coupled with fibre-glass reinforced polymer able to perform in most demanding surroundings.Water and Dust Proof for Heavy Duty ApplicationsSuperstrong materials and water resistance make Otto fan incredibly durable. IP68 rated rotor able to withstand dirt, dust, sand and water.Intelligent PWM Speed ControlIntelligent PWM speed control ranging from 0-2000 RPM, ensures efficient and silent cooling delivery during higher and lower loads. Connected via a 4-pin connector.- PWM 4-pin connector- 0-2000 RPMIngenious Rotor TechnologyThree phase motor provides smoother shifts between the slots, this lowers unnecessary vibrations combined with unmatched energy efficiency.- Silent OperationEasy To CleanDetachable frame provides convenient cleaning access without the need to remove whole frame.Rubber Mounting PinsRubber case fan mounts which eliminate vibration and resonance given off by fans by isolating them from the case.- Tool-free installation- Anti-VibrationApplicationHeatsink / RadiatorIndustrial applicationDimension120 x 120 x 25mmFan Speed0-2000 RPMMax Airflow95.68 CFMMax Static Air Pressure3.84 mm H2ONoise Level7.1-30.2 dB(A)Voltage Rating12V DCRated Current0.21ABearingTwo Ball BearingConnector4-pin PWMColourGreyContentsOTTO SC12 Fan4 x Rubber PinFan Life Expectancy80,000 hours
