This would indicate that the computer is overheating.

I would look at the cooler first.

It does sound like an overheating computer they are designed nowadays to shut themselves down if there is a problem

What you should do is check the fan assembly If you see a build up of gunk and debris then get yourself a can of compressed air used for cleaning computers and take the unit outside.

Whilst wearing glasses use the nozzle on the can to blow out any debris from the CPU and power supply.
If everything went to plan you should now be back in business.

Another consideration is that many cases have places in them for extra fans and usually extra connections on the motherboard too.

They are quick and easy to fit.

Quite often I will fit TWO in what is called a push/pull configuration. One pulls cool air in while the other pushes hot air out.

These will not only help keep the computer cooler but also cleaner

Open the case and see if dust is around the fan. If it is, then get a can of air and gently blow the dust off. You can also replace the fan. These go out quite often due to them being on all the time. If you have an old computer, you may be able to use the fan from it, if it will fit. Or you can buy one cheap off eBay. Be sure you are grounded when opening the computer case so you will not get static electricity in the computer and make sure it is unplugged.

There are two different types of fans in a computer.

Open the computer and look at the CPU fan. Is it turning. Also, if you hear a grinding sound, it is the power supply fan and you might as well just get another power supply.

Also, if the system is pretty dusty, used compressed air to clean out the system.

As more dust gets into a system it actually dries out the bearings.

Noisy


The noise could be from dust that gets in cpu fan or power supply fan. Clean them but do not open the power supply. Better replace your power supply.

Noisy computer after cleaning fan


If you used compressed air, the fan maybe was rotating too much when you blowed it. If you damaged it, replace it.

Fan noisy


Two common factors why CPU fans are noisy:

1. The collected dusts under your fans.
2. Your computer is running over the neutral power that your Power supply can handle, i.e. overclocking, high graphical games and videos.

solutions:
1. clean fans (power supply fans, exhaust and others)
2. replace CPU fans with branded and proven to be quite fans.. it may be an additional cost but proves to be very silent. :)

Noise from computer


It could very well be the noisy fan. Try tapping the computer lightly to see if the noise stops or changes to confirm if it indeed is the fan. Or it could be a noisy HDD.  There is nothing you can do about a noisy HDD but about a noisy fan you can stop worrying as it will cause no probs as long as it is working, noisily or otherwise. You will have to tolerate it. Sometimes it is the detatchable sides of the computer (you wrote 'computer' in your question). See if the noise stops or lessens when you touch the sides a little harder.

My hp pavilion a6110n product nogg781aa .Has anoisy cooling fan .How do I chang it.


If it's the processor fan that's noisy you can purchase a replacement. The fan and heatsink are normally a complete assembly you can find from many vendors online. This computer has a type AM2 socket; you need to make sure to get a cooling fan for that type. Be sure the replacement will fit into the same space as the original.

If it's the power supply fan thats loud, there may be a couple of possible causes. It may just be a noisy fan, in which case you can replace the power supply. Make sure to get one that has at least the same power rating as the original. Or the fan may be running at its maximum speed. I don't know about this computer in particular, but many computers control the fan speed depending on how hot the processor is (determined by sensors built into the main board). If the fan is running at its top speed, it can be quite noisy. This might be due to a defective power supply or problems with the fan control on the system board
