Is cleaning laptop fan important?

Located in the cooling system, the laptop fan has a direct impact on the performance of a laptop. When running, the CPU processor and graphics card generate heat continuously and if the temperature is too high continuously, the laptop's speed will automatically decrease to keep the components operating normally.

In addition, if the CPU and graphics card always operate at high temperatures, it will cause the laptop to have a reduced lifespan and break down quickly. Every 4-5 months, you should clean the heat sink, especially the laptop fan, to avoid the above problems and prolong the life of the device.

Note: If your laptop is still under warranty, you should not remove the bottom cover yourself, because your warranty will be void. In this case, you can wait until the warranty expires or go to the service center for technical support.
