In the video, a person is seen holding a black fan with a metal frame and a black grill. The fan has a label on the back with a barcode and some text. The person is demonstrating how to install the fan into a computer case. The case has a black interior with a white plastic base and a honeycomb-patterned vent on the side. The person carefully aligns the fan with the vent and then attaches it to the case using screws. The fan is then secured in place, and the person gives a thumbs up to indicate that the installation was successful.
