For PCs and laptops, fans are as compulsive as wheels to a car as they help to cool the internals that would otherwise heat up. In short, they regulate the thermal temperature of the laptop. If the fans do not work well, then the inner components such as the battery, hard disk or the motherboard will be damaged by heat. In this forum some of the main reasons why the fan on laptop is loud is the following:
1. Heavy load on the processor
2. Hard drive failure might be near
3. Malware infection
4. Blocked/dirty air vents
5. The laptop's disks are full
6. You haven't updated drivers
