No additional fan is installed because the mainframe's built-in fan must reach more than 80 ° to begin dissipating heat. Completely modified to match the original base's design The heat dissipation effect is unaffected by standing or lying down. USB port, simple to set up It does not obstruct the host port and has USB3.0 output.
