Galaxy S9/S9+: What is the noise coming from DeX Pad after Connecting my S9?
If you use an app that requires a lot of power or use it for a long time, your smartphone may generate heat. To prevent overheating, the fan inside the DeX Pad will start running once it reaches a certain temperature. When the temperature drops, your DeX Pad fan will turn off automatically. Therefore, don'‘t worry about the fan running and enjoy your DeX Pad.
