Ventola Noiseblocker eLoop B12-4

The Noiseblocker eLoop B12-4 is a 120 mm computer case fan engineered to provide effective airflow with reduced acoustic output. Designed for installation in desktop PC cases, the fan has a compact 120 x 120 x 25 mm profile and operates at 12 V. With a maximum rotational speed of 2400 RPM it produces an airflow rate of approximately 150.3 m³/h, enabling consistent cooling of system components while maintaining a restrained noise signature. The fan’s white finish integrates into a range of build styles and case interiors.

Advantages

The eLoop B12-4 balances high airflow and controlled noise by using a blade and motor design optimized for efficient air movement at elevated RPM. Its 120 mm form factor fits standard case mounts and supports focused cooling of hotspots such as processor areas, graphics cards or power supply intakes. The fan’s durable construction and standardized dimensions make it compatible with most consumer PC cases and cooling configurations.

Suitable for

• Case ventilation for gaming and workstation PCs
• Intake or exhaust mounting in ATX, micro-ATX and Mini-ITX enclosures
• Replacement or upgrade of existing 120 mm case fans
• Systems requiring higher airflow within a compact fan footprint

How to use

Install the fan into a compatible 120 mm mounting location in your computer case, aligning the screw holes and ensuring the airflow direction matches the intended intake or exhaust orientation. Connect the fan to a motherboard header or fan controller that supplies 12 V and supports the fan’s connector type. Secure the fan with appropriate screws or vibration-damping mounts, and verify the fan spins and reports speed correctly before full system operation.

Recommendations

For optimal performance, place the fan to create a balanced airflow path through the case: typically front or bottom for intake and rear or top for exhaust. Monitor case temperatures after installation and, if supported, use a motherboard or fan controller to adjust speed profiles to balance cooling needs and acoustic levels.
