It depends in how hard the computer is working and how hot it gets.
If it overheats (the fan is blocked or isn't enough to keep it cooled), then yes it is :)

The statement about physically protecting your computer that is false is "data line surges can be blocked by using a computer sound". Statements that are true include that it is best to unplug your computer during a storm and placing your computer in such a position that the fan's input vents are not blocked is important.
your computer could demage when you block the fan under it,and when you use your computer.
the computer fan is always on, as long as the computer system is on, to prevent excess heat from destroying the prosessor. so on that note, i will tha one thing that could damage the fan, is when there is any thing on it motion path, such that it can couse a break down on the fan but, it's not a garranty that the fan will be damage.
it will run with minimum current
An exhaust fan is a system fan that blows (usually warm) air out of the computer.
Check; coolant, fan, fan clutch and fan clutch solenoid, blocked or partially blocked lines and coolant gallery.
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.
It depends on the computer. For example, a tablet can run for a very long time without a fan, so they don't even have fans. Many high quality desktops have liquid cooling. In a laptop or a low quality desktop, it won't run very long without a fan, especially if it's working hard. Maybe a couple seconds?
* Return air is blocked * Filter is loaded * The fan (squirrel cage style) is clogged with dust * A duct has become crushed, blocked or disconnected. * The fan motor is burned out.
A computer fan is any fan inside, or attached to, a computer case used for active cooling. Hope its helps :)
