The fan tries to stop your computer from going into self destruct mode and is due to excessive heat. The steps you must take are:
1. Buy some cooling liquid at best buy for around 5$
2. Pour a little of it onto the fan
Caution: This can and will
fry computer
make a mess
destroy computer's internal hardware
can harm you
*This may not cool down your computer*
The fan comes to cool the computer
i'm assuming you mean your computer processor fan. If so, replace it. It's dead!
Many computer fans are thermostat controlled. When the CPU temperature gets above a certain point, the fan comes on and runs until the temperature drops.
The computer has wires and microchips but does not have gears. Do you mean the fan.
It means its broken!

An exhaust fan is a system fan that blows (usually warm) air out of the computer.
The computer's fan does nothing more than help cool the computer's internals. The fan will not have any impact on the speed of the computer if it is working properly.
Although, there are cheaper graphics cards that come without a cooling fan, these are not recommended. Go with the cheapest AVI that comes with the fan and is compatible to your system.
It means the computer comes with Windows 7.
A computer fan is any fan inside, or attached to, a computer case used for active cooling. Hope its helps :)
