NoiseBlocker Multiframe M12-P 120 mm Computer Case Fan, 2000 RPM, 133 m³/h, 4.5 V, Black

NoiseBlocker Multiframe M12-P 120 mm Computer Case Fan is a black 120 × 120 × 25 mm cooling fan designed for improving chassis airflow and assisting CPU/GPU cooling in desktop systems. The fan reaches up to 2000 RPM and provides an airflow rating of 133 m³/h while operating at 4.5 V. Developed with NoiseBlocker’s Multiframe design principles and German-engineered drive and bearing technology, this fan targets quiet, reliable case ventilation with a vibration-minimised frame and reinforced construction.

Advantages

The Multiframe M12-P uses a multipart, vibration-resistant frame with integrated structure-borne sound absorbers and a glass fibre-reinforced chassis to reduce transmitted vibrations. Its drive system and low-noise bearing design ensure a low start voltage and reduced impulse noise for quieter operation. Additional protection features include reverse-pole and overload protection plus an automatic restart function, supporting long-term reliability and a multi-year warranty period.

Suitable for

• Case ventilation for mid-tower and full-tower desktop PCs
• Assisting CPU or GPU cooling as an intake or exhaust fan
• Systems where low vibration and reduced acoustic transfer are important
• Replacement or upgrade of standard 120 mm system fans

Key specifications

• Fan diameter: 120 mm
• Dimensions: 120 × 120 × 25 mm
• Maximum rotational speed: 2000 RPM
• Airflow: 133 m³/h
• Rated operating voltage: 4.5 V
• Colour: Black
• Multipart vibration-damping frame with glass fibre reinforcement
• Low-noise bearing and wide-range drive for reduced impulse noise

How to use

Install the NoiseBlocker Multiframe M12-P into any standard 120 mm fan mount in the computer case using the four mounting points. Orient the fan so airflow direction matches intake or exhaust needs indicated on the fan housing. Connect the fan to a compatible fan header or controller that supports the specified voltage; ensure cable routing does not contact moving blades. After installation, verify secure mounting to prevent vibration transfer and confirm the fan starts reliably at system power-up.

Recommendations

For the quietest operation, mount the fan using soft rubber grommets or vibration-damping screws and place it where unobstructed airflow is available. Use as either intake or exhaust depending on thermal layout—combine with case filters to prevent dust buildup and perform periodic cleaning. Ensure the fan’s voltage and control method match your motherboard or fan controller to maintain intended performance and low-noise characteristics.
