Do you mean does it have to run/spin?
Yes, it is very important that this fan works otherwise the core will get too hot. if it gets too hot, you risk damaging (melting) components. most computers have a sensor that will shut off the computer if it gets to hot, but to be on the safe side, i wouldn't use the computer until the fan is replaced.
However, there is the possibility that you are using a passive cooling setup if your computer is fairly old (more than 5 years) in which case, there shouldn't be a fan so its not a problem as long as it has been running fine up until now.
Or, you could have a water cooling setup but if you have to ask about the fan, you probably don't have it water cooled
The fan unit helps keep the critical components of the computer cool to prevent overheating (i.e. processor, hard drive, motherboard, etc). The processor is especially susceptible to overheating and can actually melt a little if it gets too hot, ruining the processor and the entire computer.
The answer is the motherboard.
A computer with a fast processor will work faster, but will not have a noticeable effect on your download speeds.
Dust and dirt are the most common cause, but yes, the MB power or fan control could also be the problem.
A central processing unit (CPU), is under the fan and heat sink. The processor creates a lot of heat as it works, and would soon burn-out if not cooled.
The heat sink absorbs the heat from the processor and then the fan disperses the heat.
There is a certain operating range for each type of processor. As long as you install the proper heatsink and fan, your processor should never overheat. If you plan to overclock your processor, (make it work faster than it's really intended to) then you need to take the necessary steps to keep it cool. Such steps can include adding a bigger heatsink, a faster fan, and/or adding liquid cooled hoses to it.

Processors themselves don't make any noise; it is the cooling fan. The noise a particular computer puts out can vary by model of processor, brand of cooling fan, size of cooling fan, and age of the cooling fan. As such, there is no definitive answer to your question.
If you buy a retail boxed processor, yes. You do get a heatsink fan (HSF) with the processor.
A computer fan is any fan inside, or attached to, a computer case used for active cooling. Hope its helps :)

You can run it until the processor overheats and shuts down which will not take long. Eventually the processor ECU will fail due to overheating and you will be replacing it.
The power supply is what provides power for everything in your computer (processor, disk drives, hard drives, fans, etc.). If your power supply fails your computer can't turn on at all (no activity). The VGA card is your graphics card. If the VGA card fails your computer will still turn on but you won't see anything on your monitor (no graphics). The processor fan is the fan that sits on top and cools your main processor. If your processor fan fails and the computer continues to stay on it's likely that you processor will overheat and be ruined. If your main processor is fried your computer will turn on but windows will not boot up and you may see an error message on the screen.
i'm assuming you mean your computer processor fan. If so, replace it. It's dead!
