Advanced Blade Design

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.

Perfectly Fine-Tuned P-Q Curve

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.

Water and Dust Proof for Heavy Duty Applications

Superstrong materials and water resistance make Otto fan incredibly durable. IP68 rated rotor able to withstand dirt, dust, sand and water.

Intelligent PWM Speed Control

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.





Ingenious Rotor Technology

Three phase motor provides smoother shifts between the slots, this lowers unnecessary vibrations combined with unmatched energy efficiency.

Easy To Clean

Detachable frame provides convenient cleaning access without the need to remove whole frame.





Rubber Mounting Pins

Rubber case fan mounts; eliminate vibration and resonance given off by fans by isolating them from the case.





Advanced Auto Industry Structure Design

Patented spring-like anti-vibration structure ensures minimum vibration noise output. Coupled with fibre-glass reinforced polymer able to perform in most demanding surroundings.
