AEROCOOL COSMO12FRGB 120mm computer case fan, 1000 RPM, 15 LEDs RGB, Molex connector, 3.72 W, black

The Aerocool COSMO12FRGB 120mm fan combines fixed RGB LED lighting with a Molex power connector for easy installation in systems without 4-pin or 3-pin fan headers. Its curved blade design increases air pressure to improve cooling performance while maintaining low noise thanks to a sleeve bearing and a maximum rotational speed of 1000 RPM. The black finish fits a wide range of PC builds.

Advantages

Fixed RGB LEDs provide consistent lighting effects without needing an RGB controller. Curved fan blades enhance air pressure and airflow efficiency, helping to cool components effectively. The Molex connector allows compatibility with older or simpler power supplies. Sleeve bearing construction reduces operational noise for quieter operation.

Suitable for

• Case ventilation in desktop PCs
• Replacement or additional 120 mm fan for systems lacking fan headers
• Silent or low-noise builds requiring modest airflow
• Systems where fixed RGB lighting is preferred over addressable RGB

Key specifications

• Fan diameter: 120 mm
• Maximum speed: 1000 RPM
• Maximum air pressure: 1.1 mmH2O
• Bearing type: sleeve bearing
• Connector: Molex
• Colour: Black
• Lighting: Fixed RGB LED

How to use

Mount the fan in a compatible 120 mm fan slot in your PC case using the provided screws or compatible fasteners. Connect the Molex plug to an available Molex power cable from the power supply. Position the fan so air flows in the intended direction—typically intake at the front/bottom or exhaust at the rear/top of the case. Ensure cables are secured away from the blades before powering the system.

Recommendations

For optimal cooling and noise balance, use the COSMO12FRGB at its default voltage via the Molex connector and avoid obstructing airflow. Combine with additional case fans for improved overall airflow and monitor temperatures after installation to confirm adequate cooling performance.
