This video will demonstrate replacement procedure of a Fan on Vostro 3510.
To remove the fan, remove the 6 screws securing the base cover and the 2 screws by the hinges. Pry the cover off the recess points near the hinges, identify the fan and unplug the cages. Remove the 2 screws and lift the fan out of the system.
To reinstall the fan, place it back in the system and tighten the two screws, reconnect the cables. Place the base cover back on the system and secure it with the screws.
