This makes it particularly useful for equipment that needs continuous airflow in noise-sensitive environments, providing additional cooling while remaining exceptionally discreet during operation. Adjustable Multi-Speed Controller The included in-line speed controller gives you greater control over the balance between cooling performance and operating noise. Increase the fan speed when additional cooling is required or reduce it when only gentle airflow is needed. The integrated power switch also allows the fan to be conveniently switched on and off without disconnecting the USB cable. 26 CFM Airflow from a Compact 80mm Fan Despite its compact dimensions, the MULTIFAN S1 can deliver up to 26 CFM of airflow at speeds of up to 2,000 RPM. This makes it ideal for providing targeted airflow around electronics and equipment where larger circulation fans would be impractical. Premium Dual-Ball Bearings The MULTIFAN S1 uses a premium dual-ball bearing system designed for long-term continuous operation. With an expected lifespan of up to 67,000 hours, the fan provides excellent durability for applications where dependable cooling is required for extended periods. The dual-ball bearing design also allows the fan to be operated in either a horizontal or vertical position without compromising performance. USB Powered for Easy Installation The MULTIFAN S1 is powered directly through USB, making installation quick and straightforward. It can be connected to compatible USB power supplies, computers and other equipment with suitable USB power outputs. The low-power design consumes approximately 1.1 watts, providing efficient continuous cooling without significant energy consumption. Daisy Chain Multiple MULTIFAN Units Need more airflow? Each MULTIFAN S1 features an additional USB connection that allows compatible MULTIFAN S Series fans to be daisy chained together. Up to four compatible fans can share the same USB power source, making it easy to expand your cooling setup without requiring a separate power connection for every fan.
