Re: Fan is continually running
Some are controlled by a thermostat. It could be the thermostat isn't working. It also depends on what the temperature of the room is that you have it in. If the room doesn't have air conditioning, chances are it needs the fan.
One way to try to cut the noise is try to clean the dust out of the fans and power supply by taking and air compressor or using some canned air. You should be very care when using the air compressor to make sure that you don't knock off any components.
Insect your fans and power supply. There are less noiser ones you can find at a computer store for a reasonable price. It could be the bearings are bad on a fan as well. If you replace it, the noise will go away.

Usually the fan stays on because your PC is overheating! First try and see your PC has at least 5 cm (2 in) space all round.
You computer fan may have accumulated a lot of dust, which causes the fan to run continuously. Purchase compressed air spray and spray the computer fan to loosen up any dust that may have accumulated. Most computer fans are exposed, so accessing the fan should not be a challenge. Brush the blades with a soft artists brush if the dirt is still on, but GENTLY
3. Technical issues
In some cases, your computer may have either a defective fan or thermostat. Some Computer providers allow you to purchase a new fan and replace it yourself. For thermostat issues, you may have to contact a computer repair professional for assistance.
4. Computer is overworked
Depending on the age of your computer multiple programs that are running can cause it to overheat. Watching a lot of DVDs, playing video games, and listening to music on your computer also can cause overheating. Considering closing some of your programs and rebooting your computer.
I'm assuming your desktop has an AMD processor?
AMD have a process called "quiet and cool" this basically speeds up the fan when the processor is under load and getting hot or slows it down when the processor isn't working as hard.
Usually, there are two fans on a desktop PC. Some computer have three.
One cools down the power supply and it may be quite noisy after a while because the dust in the fan. The second one is to cool down the processor and usually it doesn't stops, it only changes its speed according the heat.
If there is a third one, it will stop when the temperature is cool enough for the system.
Only on notebooks the processor fan stops completely after a while to save some energy.
If your fan is not turning at all then it is probably dead, the bearings are likely clogged with dust and such. The PC is shutting off because of heat buildup on the processor chip. You need to do an Ebay search for your model and order a fan right away. Continued running of your sysem without a fan will kill the processor and motherboard. You should be able to get a replacement fan for your computer for less than $15 including shipping. Your local computer store may have one to fit your system but they may charge more for it. To change the fan is very easy, the left side of the case will come off your system, right under the power supply is the processor and heatsink and the fan. Disconnect the old fan and reconnect the new unit.
More likely one of the fans, but could be the hard drive. Open the case and listen. Fan on power supply, fan on processor, or hard drive are the most likely sources of the noise. Processor fans and power supplies are both cheap and easy to replace. Hard drive is a bit more expensive and you must back it up (which you already regularly do, right?) if you want to keep your data.
