Disconnect the Dock’s DC power adapter. Once the Dock is powered off, the fan will stop operating.

Please note that when the Dock is powered on and operating for an extended period under load, the fan may start automatically to support normal operation.

The fan noise you may hear is normal behavior and is related to the device’s cooling design:

1. The device uses a dedicated cooling fan to maintain stability during high-power and full-load operation.

2. When the device is under higher performance load, the fan operates to reduce internal temperature and ensure reliable performance.

FusionDock Ultra is equipped with a high-performance cooling system integrated with an NTC temperature sensor module.

The fan speed is dynamically adjusted based on the device’s operating load to achieve intelligent thermal control:

-Low temperature / low speed:

< 20 dB, comparable to quiet breathing

-High temperature / high speed:

< 50 dB, comparable to a library environment

If you find the fan noise noticeable, try reducing the number of connected peripherals or returning the Dock to a lower-load operating environment to allow the fan speed to decrease.
