Question about PC Desktops
1) Unplug the power cord and give the fan a good cleaning
with a soft paint brush and a vacuum cleaner.
i.e. Let the fans spin up by the vacuum and than bring
the brush against it.
2) If this fails, it's time to replace the fan:
a) Upgrade or replace the power supply enclosure with more
This is usually a good investment anyway.
b) Replace the fan only as described below:
Unplug the power cord
Open up the computer (remove sides)
Unplug all the power supply harnesses from
the mother board, drives and chassis fans.
Unscrew and remove the complete power supply
enclosure at back of computer (ie top of the tower)
Vacuum it out as much as possible.
Disassemble the power supply enclosure by removing
more screws and removing the metal cover.
Unplug the fan from the circuit board, remove it
and take it to a computer store/ builder.
buy another fan just like it
reverse the process to put your computer back together.
1) A new power supply should cost $65 to $120
depending on power and quality. The bigger the better.
But make sure it fits mechanically into the existing chassis
and that the AT generation matches ***********-board.
2) A new fan should cost $15 to $25. Makes sure it runs on
the same voltage, and that it is physically compatible.

The motherboard may have the bulging capacitor issue.
The fan is getting no instruction from the mobo so just goes spin crazy.
Do you have a solid amber or flashing amber power LED?

Often, just dust can make fans noisy. You can unplug everything, take the side cover off of your tower, and blow it out with a can of the air duster you can buy at a computer store, paying close attention to the fans. If you are not comfortable with this, a local shop should be able to clean it up for you for not a lot of cash, and if a fan is really bad, they could identify which one it is for you too.
