AC Infinity MULTIFAN S2 Quiet USB Cooling Blower (120mm)
The AC Infinity MULTIFAN S2 is an ultra-quiet, low-profile 120mm USB-powered cooling blower engineered to extract trapped heat from constrained electronic environments. Unlike standard axial fans that exhaust air perpendicularly, this centrifugal blower is designed to pull heat upward from the bottom intake and exhaust it out of the rear. This unique airflow direction makes it the perfect thermal management solution for component stacks and tight shelving units with minimal top clearance. Equipped with a 3-speed inline controller, it allows you to easily balance optimal airflow volume against acoustic requirements.

Key Features & Benefits

Exhaust-Optimised Blower Design: Centrifugal architecture draws rising heat away from hot components and forces it out the back, making it highly effective for low-clearance setups.
In-Line 3-Speed Controller: Features a tactile multi-speed cord switch (Low, Medium, High, and Off) to adjust performance and noise levels based on your components' thermal load.
Modular USB Daisy-Chaining: Equipped with an integrated pass-through USB port, enabling up to four MULTIFAN series units to link together and share a single USB power source.
Premium Dual-Ball Bearings: Heavy-duty dual ball bearings grant a massive lifespan and allow the blower to operate flawlessly flat or standing upright without rotational resistance.
Vibration-Damping Silicone Mounts: Includes four pre-attached silicone feet on the bottom of the blower frame to isolate motor vibrations and eliminate resonance on cabinet shelves.

Best Uses & Applications

Component-Top Heat Extraction: Position directly over the upper ventilation grilles of hot AV receivers, DVRs, modems, or cable boxes to accelerate hot air removal.
Low-Clearance Shelving: Ideal for tight home theatre media consoles, stereo racks, and entertainment centres where standard axial fans have no room to breathe.
Gaming Console Exhaust: Placed atop or near video game consoles to draw out trapped thermal heat during long, high-performance hardware rendering cycles.
Enclosed Networking Closets: Stand upright or lay flat inside narrow computer desks, server racks, or smart home hubs to flush stagnant hot air away from hardware components.
