The AC Infinity MULTIFAN S7 is a UL-certified dual 120mm USB fan designed for thermal management of electronics such as AV receivers, DVRs, PlayStation, Xbox, and computer cabinets. Its compact frame is constructed from durable ABS plastic, with a matte black finish that blends into most entertainment centers and server racks. Each fan measures 120mm by 120mm by 25mm, and the two units are paired together with a single USB-powered cable, simplifying installation. The blade design prioritizes quiet operation while maintaining adequate airflow for heat dissipation. Rated at 10.5 CFM per fan at a low noise level of less than 21 dBA, the MULTIFAN S7 provides a balanced solution for enclosures that require consistent cooling without intrusive hum or vibration. The unit draws power from a standard USB port (5V DC), consuming a maximum of 0.15A total, making it energy-efficient and compatible with most devices. Internal components include a brushless motor with a sleeve bearing, rated for continuous use and long service life under normal conditions. The build quality emphasizes reliability: the grille is integrated into the housing to prevent finger access, and the wiring is neatly sheathed to avoid interference. During operation, the fan generates a gentle breeze that moves warm air away from sensitive electronics, reducing the risk of overheating and performance degradation. For cabinet and rack setups, the dual-fan configuration allows for strategic placement—either pulling air in or exhausting it out—depending on user needs. The included USB cable measures roughly 60 inches, offering flexibility in routing within crowded spaces. No software or driver installation is needed; simply plug into any USB port, and the fan begins running at a fixed speed. The MULTIFAN S7 is particularly suited for home theater systems, gaming consoles, and network equipment enclosures where space is limited and quiet cooling is essential. Its slim profile (25mm thickness) permits mounting in tight gaps, and the lightweight construction (approximately 0.55 lbs per fan) allows for easy attachment with double-sided tape or screws (not included). The product is UL-certified for safety, meeting electrical and fire hazard standards. While not designed for high-heat scenarios like PC overclocking, it excels in low-to-moderate thermal loads, ensuring components stay within optimal temperature ranges. The dual-fan design doubles airflow capacity compared to single-fan USB models, yet remains compact enough for dual use in a single cabinet. The affordability of this unit is noteworthy: priced competitively, it offers a practical cooling upgrade without requiring complex wiring or additional power supplies. Long-term durability is supported by the fan’s metal sleeve bearing and low current draw, which reduce wear and energy costs. The absence of RGB lighting or speed controls keeps the focus on function-first cooling, appealing to users who prioritize performance over aesthetics.

The AC Infinity MULTIFAN S7 delivers reliable, quiet airflow for electronics enclosures, built with quality materials and safety certifications that inspire confidence in continuous operation.
