The AC Infinity Multifan S3 USB Cooling Fan 120MM is an ultra-quiet and high-performance cooling fan designed to prevent overheating in electronics, AV equipment, and DIY projects. Featuring a large 120mm fan with dual-ball bearings, this USB-powered cooling solution delivers strong airflow while maintaining quiet operation.
Providing 52 CFM airflow at only 18 dBA, the MULTIFAN S3 efficiently cools receivers, modems, routers, gaming consoles, amplifiers, DVR systems, and other sensitive electronics. The included inline multi-speed controller with power switch allows users to easily adjust fan speed to achieve the ideal balance between airflow performance and noise levels.
Engineered for flexible installation, the fan can be placed flat or upright and mounted horizontally or vertically, depending on the cooling setup. The 6-foot USB cable allows convenient connection to USB ports located on televisions, receivers, computers, and portable power banks.
Each unit includes eight large anti-vibration rubber feet to reduce noise and stabilise the fan during operation. An integrated USB daisy-chain port allows up to four MULTIFAN units to share a single USB power source, enabling expanded cooling setups when additional airflow is required.
Built with UL-certified AC Infinity axial fans (ACX-FD1225(B)05W5) and premium dual-ball bearings, the MULTIFAN S3 ensures dependable performance with a 67,000-hour lifespan, making it ideal for both professional installations and DIY electronics cooling projects.
