Rubber mounting pins included.</strong></em></span></h3> <p> &nbsp;</p> <ul> <li> Advanced auto industry structure design</li> <li> IP68 rated rotor technology</li> <li> Advanced blade technology</li> <li> Intelligent PWM speed control</li> <li> Easy to clean</li> <li> Rubber mounting pins</li> </ul> <p> <br /> <br /> <br /> <br /> <br /> <span style="font-size: 16px;">Advanced Blade Design</span></p> <p> Advanced S-flow design provides a stronger and more centralised airflow making it perfect for either pushing cool air into a case or pulling hot air out of the case. Ideal also for heavy duty applications.</p> <p> <br /> <br /> <br /> <br /> <br /> <span style="font-size: 16px;">Perfectly Fine-Tuned P-Q Curve</span></p> <p> Otto SF12 has been carefully fine-tuned for optimising airflow in the intersection relative to the PC case fan applications in order to maximise the overall performance of the fan.</p> <p> <br /> <br /> <br /> <br /> <br /> <span style="font-size:16px;">Water and Dust Proof for Heavy Duty Applications</span><br /> <br /> Superstrong materials and water resistance make Otto fan incredibly durable. IP68 rated rotor able to withstand dirt dust sand and water.</p> <p> <br /> <br /> <br /> <br /> <br /> <span style="font-size: 16px;">Intelligent PWM Speed Control</span><br /> <br /> Intelligent 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.<br /> <br /> <br /> <br /> <br /> <br /> <span style="font-size: 16px;">Ingenious Rotor Technology</span></p> <p> Three phase motor provides smoother shifts between the slots this lowers unnecessary vibrations combined with unmatched energy efficiency.</p> <p> <br /> <br /> <br /> <br /> <br /> <span style="font-size: 16px;">Easy To Clean</span></p> <p> Detachable frame provides convenient cleaning access without the need to remove whole frame.<br /> <br /> <br /> <br /> <br /> <br /> <span style="font-size: 16px;">Rubber Mounting Pins</span></p> <p> Rubber case fan mounts; eliminate vibration and resonance given off by fans by isolating them from the case.<br /> <br /> <br /> <br /> <br /> <br /> <span style="font-size: 16px;">Advanced Auto Industry Structure Design</span></p> <p> Patented spring-like anti-vibration structure ensures minimum vibration noise output. Coupled with fibre-glass reinforced polymer able to perform in most demanding surroundings.</p> <p> &nbsp;</p>
