Integration of fans into applications creates difficult design challenges, especially when it comes to noise. To achieve a low fan noise, an open airflow and space is required. In real applications miniaturization reduces the available space required by the fan. This creates design situations with tradeoffs between space and noise.
To solve this tradeoff, RotoSub-enabled fans has a built-in active noise control system, effectively reducing the noise generated by the fan. The active system also reduces the impact of surrounding components disturbing the fan, making low noise integration easier.
RotoSub-enabled fans has the same form factor as traditional fans and integrates into the same space.
