Description

The MULTIFAN S7 is an ultra-quiet dual 120mm USB cooling system designed to keep AV electronics, gaming consoles, modems, computers, and other components running at safe temperatures. Each fan can operate standing upright or lying flat, making it flexible for various equipment setups. The in-line multi-speed controller allows precise adjustment of airflow and noise, while dual ball bearings provide long-lasting performance in both horizontal and vertical positions.

A built-in USB passthrough port allows daisy chaining additional fans from a single power source. Anti-vibration rubber feet help reduce noise and maintain stability during operation.
