Is the laptop dirty inside?
If it hasn't been cleaned out regularly, with a can of compressed air for computers, more than likely it is.
Laptops typically have a poor cooling design. For one, everything is crammed into a tiny box.
For two, there is a small duct, (Air Intake Duct), that draws air in.
For three, laptops typically just have 1 small fan.
For four, the Air Intake Duct is located on the bottom of a laptop, or on the side.
This is an excellent (?) area to draw foreign debris in. Another word for foreign debris, would be CRUD.
Hair, Food Crumbs, Lint, Dirt, Dust, and so on.
A laptop's cooling systems primary function is to keep the Processor at a certain temperature. If the processor becomes too HOT, it turns off. (BIOS turns it off)
NO Processor, No computer!
1.The excessive fan noise can be that the fan is spinning at top rate, trying to keep the processor cool. It's having a hard time doing that, because the fan cannot draw enough air in. (Clogged Cooling System with Crud)
2.The excessive fan noise could be that the fan's bearings are bad.
3.The excessive fan noise could be that the Processor is running at 100 percent, (100%), and the fan is running at full speed, in order to keep the processor cool.
Perhaps caused by a virus, or some sort of anti-virus program, or running more than one virus program. (Installed a new anti-virus program lately?)
