These dirt particles will accumulate more and more over time and if you do not clean your laptop periodically, they will stick thickly to parts of the cooling system such as heatsinks, fans, guides, etc.

This can block the circulation paths between the inside and outside of the machine, causing unpleasant noise or possibly jamming the system, causing the laptop fan to not run.

1. During travel, do not put your laptop in a shockproof bag as other hardware and the fan will collide with each other.
2. Many people often have the habit of leaving their laptops on the mattress to work. This also causes the laptop fan to make loud noises because the device cannot escape heat.
3. During the process of disassembling the fan incorrectly, heat is blown back into the machine.

A damaged or broken fan blade will cause the fan to rotate unevenly. Over time, the fan and contact parts become loose, the sound becomes louder and more annoying.

The fan's oil is dry and the CPU thermal paste is gone

If your laptop has been used for a long time but you have not changed the CPU thermal paste, this is also one of the main reasons why the laptop makes loud noises. 

Because the glue is the membrane that helps the cooling fan operate more smoothly and evenly. When the glue dries, the fan will have to work harder. This causes the laptop fan to make a loud noise.

Laptop is infected with malware
