Laptops, as computers, generate heat while working and one of the ways to control and regulate their temperature is through the use of small fans. These fans expel warm air generated by laptop processors or other components and also draw cooler air inside. Since laptop fans control the operating temperature and directly influence the performance of the processor, it is necessary to replace or repair a broken fan immediately. A broken fan can cause a laptop to freeze or shut down and can even lead to more serious damage.
Turn off your laptop before starting the repair process of the fan.
Access your laptop fan by removing the cover that protects it. Use a small Phillips screwdriver to remove the screws that hold the cover and then lift the cover off, revealing the fan inside.
Inspect the look and the condition of the broken fan. If the damage is too severe, it might be best to replace the whole fan and not just the broken blades.
Clean the inside of the fan and around it as well, using a can of compressed air. Notice how lint, dirt and dust accumulate around the fan and other inside components. Remove all dust and lint with canned air, making sure there is no residue near the fan.
Use a small Phillips screwdriver to remove the case cover of the fan. Set the cover of the fan aside for later, along with its mounting screws.
Remove the old fan blade by gently lifting it from the axis. Look at the bottom of the fan case to see if there are smaller parts of the blade inside; remove them if you find them.
Place the new replacement fan blade onto the axis, making sure it fits snugly into the fan case. Note that it is ideal to buy the same brand of a replacement fan blade, as it is the most compatible option.
Re-install the case cover of the fan by tightening the screws with a Phillips head screwdriver. Reinstall the laptop fan cover as well, making sure to put everything on the same place as before.
Run your laptop fan by turning on the laptop to see and hear how it works.

For more efficient cooling process of your laptop, add an external cooling unit such as a cooling pad, available in most computer stores.
Do not run your laptop without a working fan, since it can lead to overheating the CPU and significant damage of both hardware and software.
