## Summary description

The Akasa OTTO SC12 is a 12 cm heatsink/radiator featuring a dual ball bearing design for enhanced durability and performance. With a maximum air pressure of 3.84 mmH2O, it effectively dissipates heat, ensuring optimal cooling for your computer components. The sleek grey color adds a modern touch to your setup.

## Long description

OTTO SC12 is an ultra-premium 120 mm heatsink and radiator fan designed for water-resistant and heavy-duty cooling applications. The fan uses advanced blade geometry and automotive-derived structural design to deliver high static pressure and focused airflow for heatsinks and radiators. It features IP68-rated rotor technology, a detachable frame for easier cleaning, intelligent PWM speed control (0–2000 RPM) via a 4-pin connector, and includes rubber mounting pins for vibration isolation. The model is available in grey and uses a dual ball bearing configuration for enhanced durability.
Advantages
The advanced sickle-flow blade design concentrates high static pressure into strong, focused air streams, improving cooling performance on radiators and dense heatsinks. A finely tuned P–Q curve optimises static pressure at operational points typical for radiator and heatsink installations. The patented spring-like anti-vibration structure and fibre-glass reinforced polymer construction reduce vibration and increase mechanical robustness. IP68-rated rotor technology protects the fan from dust, sand and water, while the three-phase motor and dual ball bearing design enhance smooth operation and longevity. The detachable frame simplifies maintenance and cleaning.
Suitable for
Heatsinks and radiator cooling in desktop PCs
Water-cooled radiator setups and closed-loop liquid cooling
Environments that require dust and water resistance (industrial or heavy-duty builds)
Noisy or vibration-sensitive installations where rubber mounting pins help isolate the fan

How to use
Install the OTTO SC12 onto the heatsink or radiator following the manufacturer’s mounting pattern and ensure correct airflow orientation for intake or exhaust. Connect the 4-pin PWM cable to a compatible motherboard header or fan controller to enable speed regulation. Use the provided rubber mounting pins to reduce vibration transfer to the case. For cleaning, detach the removable frame to access the blades without removing the entire unit from the radiator or fan housing.
Usage recommendations
For radiator and heatsink applications, position the OTTO SC12 to achieve direct, concentrated airflow through cooling fins. Enable PWM control to balance noise and performance according to workload; set higher RPM under sustained heavy loads and lower RPM for quiet idle operation. In dusty or wet environments, verify seals and mounting to maintain IP68 protection and periodically clean the detachable frame to prevent debris buildup.
