How to Replace a Toshiba Laptop Cooling Fan
Every laptop comes with a dedicated cooling system, and your Toshiba laptop is no exception. All laptop cooling systems are attached to the motherboard over the processor chip. This is because the cooling system's primary function is to regulate the temperature of the processor. All processor cooling systems consist of a cooling fan and heat sink device. In most Toshiba laptops, the cooling fan and heat sink are one unit, and therefore must be removed together.
Things You'll Need
- Phillips-head screwdriver
- Thermal grease
- Paper towels
Shut down your Toshiba laptop, and then disconnect all cables. Close the LCD lid, and then place the laptop face down on a flat surface. Position the laptop with front edge facing you.
Locate the battery pack near the top section of the laptop's bottom casing. Press on the battery release button. Remove the battery from the laptop.
Locate the cooling fan compartment cover. Its location varies from laptop to laptop, but it will be the only hardware cover with a vent in it. Remove the Phillips-head screws securing the fan's cover in place. Remove the cover from the laptop.
Disconnect the fan's cable from its connector on the motherboard. Remove the Phillips-head screws securing the fan in place. Lift the old fan out of the fan compartment and set it aside. Removing the old fan will reveal the processor chip. Apply a thin coat of thermal grease to the processor's surface using a clean paper towel. This will prevent your new processor from frying once you power on your laptop.
Place the new cooling fan assembly inside the fan compartment. Align the screw holes on the new fan with the screw holes inside the compartment. Replace the four retaining Phillips-head screws, and then reconnect the fan's power cable to the motherboard. Replace the fan compartment's plastic cover, and its retaining Phillips-head screws.
Replace the battery pack and reconnect all power cables and external devices. Turn on your laptop to test the new cooling fan.
