If the Processor fan is the one making the noise, it's the problem. (Fan bearings are bad)
A processor operates within a certain temperature range (Thermal range)
If the Processor becomes too hot, BIOS turns the Processor off.
This is a built-in Fail Safe feature, to keep the Processor from burning up. (Literally)
The Processor fan, (Sitting on top of the Heatsink, which in turn sits on top of the Processor), must be spinning, and MUST spin at a certain speed.
(RPM. Revolutions Per Minute)
The Acer Aspire E380-UD420A desktop computer, uses an AMD Athlon 64 X2 4200+, processor.
AMD's run H-O-T!
An AMD processor will burn up in less than 30 seconds, without proper cooling. (Intel's last much longer)
Suggest you replace that fan Pronto, if this is the fan in question!
A Fan/Heatsink combo may be easier to find than just the fan.
The AMD Athlon 64 X2 4200+ processor, uses a Socket 939 processor socket,
Information on the Socket 939 processor socket,
When buying a Fan/Heatsink combo, you look for what processor socket the processor uses. Then you look at the physical dimension size of the Fan/Heatsink combo, and determine if it will fit.
As you can see from inside your computer, the Processor sits sideways when mounted.
Therefore, you have to look at the Height of the Fan/Heatsink combo, to see if it will fit in the case.
You also have to look at the Width, and Length. There may be Electrolytic Capacitors on the motherboard, or Ram Memory module/s, or some other hardware components in the way, that may only allow a certain Width, and Length.
Just one example, of a Fan/Heatsink combo for a Socket 939 processor,
Be sure the computer is unplugged from power, before reaching inside the computer.
Also be VERY sure to observe Anti-Static precautions.
Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components, inside a computer. You probably won't even see it, or feel it.
Computer unplugged from power, computer case open, TOUCH the metal frame of the computer case, to relieve your body of Static.
IF, you get up, and walk away in the middle of working on your computer, upon your return TOUCH the metal case again.
Processors are the MOST susceptible hardware component inside a computer, to Static shock.
An average Heatsink is composed of a flat plate of metal, with tall fins protruding from it.
Heat is absorbed from the top of the Processor's case, to the metal plate, whereupon the heat is absorbed by the tall, thin fins, and radiated away.
The Processor fan pushes air in-between the fins, and helps carry the heat away.
The top of a Processor's case, and the bottom of a Heatsink, are not perfectly smooth. A microscopic view would reveal 'Pits, Valleys, and Hills'.
These imperfections create an air pocket.
AIR is an Insulator, not a Conductor.
Air does not conduct heat very well.
Thermal paste is a compound made to fill the above mentioned imperfections. It is an excellent Conductor.
It ABSOLUTELY must be used!
Do Not reuse old thermal paste. The properties of the paste break down over time. Even if the thermal paste looks to be good, don't.
The cost of good thermal paste is very little. $2 to $4 from a 'Mom and Pop' computer store, $6 on up online.
The top of the Processor, and the bottom of the Heatsink MUST be thoroughly cleaned. I use an old plastic credit card (Anti-Static, and won't scratch the processor case), to clean these areas.
I then follow with Q-tips dipped in Isopropyl Alcohol.
(Rubbing Alcohol. 91 percent alcohol is best, but 70 percent will do. NO to 50 percent. It's 50 percent water, 50 percent alcohol.
Isopropyl alcohol is Extremely Flammable!
Use in a Well ventilated area, with no sparks, or flames present)
Takes a few Q-tips dipped in alcohol to remove the gooey mess of the old thermal paste.
How clean does it need to be?
Clean enough to eat off of.
