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.
Technical Specifications
  • Blower Frame Dimensions: 120 x 120 x 25 mm (4.7 x 4.7 x 1.0 in.)
  • Total Airflow Capacity: 35 CFM (Cubic Feet per Minute)
  • Acoustic Noise Rating: 17 dBA (Whisper-quiet operational profile)
  • Rotational Fan Speed: 1200 RPM
  • Bearing Lifespan Expectancy: 67,000 Hours
  • Input Voltage Requirement: 5V DC via Standard USB
  • Power Draw & Wattage: 1.2 Watts ultra-low consumption
  • Current Draw: 0.24 Amps
  • Static Pressure Rating: 0.84 mm-H2O
  • Power Cable Length: 6 feet (1.8 metres) heavy-duty cord
  • Safety Approvals & Certifications: CE, RoHS, and UL Certified
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.

Frequently Asked Questions

The AC Infinity MULTIFAN S2 is designed to cool electronic equipment by removing trapped heat from enclosed spaces. It's ideal for AV receivers, amplifiers, routers, modems, gaming consoles, DVRs, media cabinets, network switches and entertainment centres where airflow is limited.

Unlike a traditional desk fan, the MULTIFAN S2 uses a centrifugal blower design that draws hot air in from underneath and pushes it out through the rear. This makes it much more effective in tight spaces where standard axial fans struggle to move heat away from electronic equipment.

The MULTIFAN S2 is engineered for ultra-quiet operation, producing as little as 17 dBA while delivering up to 35 CFM of airflow. Its premium dual-ball bearing motor provides reliable cooling without adding distracting noise to your home cinema, office or gaming setup.

Yes. The fan is powered by a standard 5V USB connection, allowing it to run directly from TVs, AV receivers, gaming consoles, USB adapters, computers or power banks. It also includes an integrated USB pass-through port so up to four MULTIFAN units can be daisy-chained from a single power source.

Absolutely. The MULTIFAN S2 includes an inline 3-speed controller with Low, Medium and High settings, allowing you to balance cooling performance with noise levels depending on the amount of heat your equipment generates.

The AC Infinity MULTIFAN S2 combines ultra-quiet operation, USB power, premium dual-ball bearings, adjustable fan speeds and a specialised blower design in one compact unit. Whether you're cooling a home cinema receiver, network cabinet or gaming console, it provides reliable thermal management while helping extend the lifespan and performance of your equipment.
