Fan Noiseblocker Multiframe MF8-S3HS

The Noiseblocker Multiframe MF8-S3HS is an 8 cm case fan engineered for reliable component cooling in compact PC builds. It runs on 12 V and reaches up to 2200 RPM to deliver an airflow of 59 m³/h while maintaining a compact 80 x 80 x 25 mm form factor. The fan features a multipart, vibration-free chassis with integrated structure-borne sound absorbers and a glass-fibre reinforced frame, combining high airflow performance with low acoustic emissions. The Multiframe S series pairs the NB-EKAPlus II wide-range drive and the nearly silent NB-NanoSLI® bearing to provide long service life and consistent operation, and technical data such as airflow have been confirmed by independent testing.

Advantages

The MF8-S3HS provides efficient cooling in small spaces with a high maximum speed and verified airflow while keeping noise and vibration to a minimum thanks to its vibration-free frame and sound-absorbing construction. It includes reverse polarity and overload protection plus a restart function for enhanced reliability, and comes with assembly material and an additional sealing/decoupling frame for easier installation and improved acoustic isolation. The design employs glass-fibre reinforcement and precision manufacturing to ensure durability and stable operation over an extended service life, backed by a six-year guarantee.

Suitable for

• Small form-factor desktop cases and compact workstations
• Cooling for components in tight spaces (CPU, chipset, VRM) where an 80 mm fan is required
• Systems where low vibration and reduced structure-borne noise are priorities
• Replacement or upgrade of existing 80 mm case fans

How to use

Mount the MF8-S3HS in a standard 80 mm fan location using the supplied screws and the additional sealing/decoupling frame to reduce vibration transfer. Connect the fan to a 12 V fan header on the motherboard or to an appropriate power source, ensuring correct polarity. If installed in a front or exhaust position, orient the fan so that airflow direction corresponds to your system cooling plan. The fan’s low start voltage and NB-EKAPlus II drive allow reliable start-up and smooth operation across a broad speed range. Regularly inspect the fan for dust buildup and clean as needed to maintain performance.

Usage recommendations

For best acoustic and cooling results, use the additional sealing/decoupling frame during installation and position the fan to minimize direct contact with metal panels. If noise reduction is a priority, ensure the fan is mounted on vibration-damping points and consider pairing it with case ventilation strategies that balance intake and exhaust airflow. Periodic cleaning and checking connector polarity help preserve reliability over the fan’s long service life.
