Remove A Fan From An Hp Dv9000

Remove the cooling fan from your HP Pavilion dv9000 laptop.

Every laptop comes built with a dedicated cooling system. The cooling system consists of a heat sink and a cooling fan device. In HP dv9000 laptops, the cooling fan sits directly over the processor chip. The fan’s main function is to regulate the processor’s temperature so that the processor does not overheat and damage the laptop’s motherboard. Since the fan sits on top of the processor, removing the fan is necessary to access the processor chip.
