Description

The AC Infinity Multifan S4 USB Cooling Fan 140MM is a powerful and ultra-quiet cooling solution designed to prevent overheating in electronics, AV equipment, and DIY ventilation setups. Featuring a large 140mm fan with premium dual-ball bearings, this USB-powered fan provides enhanced airflow while maintaining low noise operation.

Delivering 57 CFM airflow with only 18 dBA noise, the MULTIFAN S4 efficiently cools receivers, routers, DVRs, gaming consoles, amplifiers, modems, and other sensitive electronic devices. The included inline multi-speed controller with power switch allows users to easily adjust fan speed for the ideal balance between airflow performance and quiet operation.

Designed for versatile installation, the fan can be placed upright or laid flat and mounted horizontally or vertically depending on the cooling requirement. The 6-foot USB power cable allows easy connection to USB ports found on televisions, AV receivers, gaming consoles, computers, and portable power banks.

Each fan includes eight large anti-vibration rubber feet to minimise vibration and stabilise operation. An integrated USB daisy-chain port enables up to four MULTIFAN units to share the same power source, making it easy to expand cooling setups when additional airflow is required.

Built with UL-certified AC Infinity axial fans (ACX-FD1425(B)05W3) and engineered for long-term reliability, the MULTIFAN S4 offers dependable cooling with a 67,000-hour lifespan, making it suitable for both professional AV installations and DIY electronics cooling projects.
