Blæser Noiseblocker eLoop B12-3

The Noiseblocker eLoop B12-3 is a 120 mm case fan designed for PC cooling applications. It operates at 12 V and delivers an airflow of up to 121.2 m³/h with a maximum rotational speed of 1900 RPM. The fan's slim 25 mm profile and white finish make it suitable for installations where space is limited and a neutral aesthetic is preferred. The impeller design focuses on a balance between airflow and acoustic performance to support effective heat dissipation for system components.

Advantages

The fan combines a compact 120 mm form factor with a high airflow rating, providing effective cooling for cases, radiators and heatsinks while maintaining a modest rotational speed. Its white colour integrates into light-themed builds and helps create a uniform interior appearance. The 25 mm thickness fits standard fan mounts and allows for use in tight spaces without requiring modifications. The design aims to deliver stable airflow with reduced turbulence for consistent thermal management.

Suitable for

• Case ventilation for desktops and workstations
• Mounting on 120 mm radiators for liquid cooling loops
• Supplementary cooling for CPU and GPU heatsinks
• Systems where a white fan is desired for visual consistency

Key specifications

• Fan diameter: 120 mm
• Maximum rotational speed: 1900 RPM

How to use

Install the fan into a standard 120 mm mounting position in your PC case, radiator, or heatsink frame using compatible screws or mounting hardware. Connect the fan to an appropriate 3- or 4-pin header on the motherboard or to a fan controller that provides 12 V supply and, if available, PWM control. Orient the fan so that airflow direction aligns with your case ventilation plan: typically intake at the front or bottom and exhaust at the rear or top. Ensure there is no obstruction around the blades and that the fan is securely fastened to reduce vibration transfer to the chassis.

Recommendations

For best thermal performance, use the Noiseblocker eLoop B12-3 in matched pairs or in combination with other fans to create a balanced intake and exhaust airflow. Periodically clean dust from the blades and grille, and verify secure mounting to minimize noise caused by vibration. When integrating with liquid cooling, confirm that the fan clearance meets radiator thickness and mounting requirements.
