Yes, it is normal. You can try using a cooling pad like those made by evercool or belkin but it won't cut down on the noise much. If you have a waterbed and can place the laptop directly on the mattress the water will act like a huge heat sink and keep your unit much cooler.

Your Acer Aspire, like any other desktop computer system, contains fans inside the case to help vent the heat generated by the internal components.
These fans generally operate quietly and reliably, working in the background to prevent your computer from overheating.
A fan that sounds excessively loud could indicate a problem such as overheating or loose internal components, or it could simply be a normally loud fan.
The key to differentiating between the two involves looking for additional clues from your computer.
Normal Operation
Due to computer configuration and build quality, the fans in some desktops sound louder than others.
Depending on what other brands of computers you've owned or have had experience with, the fan in the Acer may sound louder, when it's actually functioning perfectly.
The fan will run to keep the inside of the computer from overheating, so periodic runs are normal. If the fan runs for long periods or very often, you may have a deeper problem.

Fan Damage and Overheating
A fan can sound loud due to damage, such as broken blades or to a build-up of dirt that impedes normal operation.
This dirt, as well as normal wear and usage, can wear away the lubricant coating on the fan's internal shaft, causing the blades to make excessive noise as they turn. In many cases, a loud fan indicates that the computer is overheating, causing the fan to run more often than usual to try and cool the system.
Depending on the types of components and upgrades within your Acer computer, your current fan may be too small and weak to handle the heat output, and require upgrading to a larger, more powerful fan.


Troubleshooting Take note of when the fan turns on and how long it runs to determine any distinct patterns, whether if it occurs only during certain processes or programs.
Your computer's CPU generates a large amount of heat while in operation, so programs that require large amounts of CPU usage may trigger the fan more often.
Watch for additional signs of overheating, such as sudden shutdowns or computer crashes. Check inside the case for signs of other components touching the fan and causing vibration noise.

Solution

Do not overtax the CPU by opening numerous processor-intensive programs at once.
Check that all screws, cards and wires are securely fastened and away from the fan.
Keep your computer clean inside and out, to prevent the build-up of dirt on the fan blades or air vents and minimize the threat of overheating.
Apply a drop of oil to your fan's shaft to give it proper lubrication and smooth, quiet rotation of the blades.

Loud fan


Chances are you have dirt buildup, get a can of compressed air, attach straw and give the cooling fan a few good blasts, blow out open ports. If no change, the laptop must be dismantled down to the motherboard level to do a complete cleaning and the cooling fan may need to be changed, the old thermal paste will need to be removed and fresh applied. Go to www.ebay.com Type: make and model of laptop, refine search to cooling fan.

The way you describe the problem, with the fan getting noticeably louder then shutting the computer down entirely, sounds like an overheating issue; the fan spins up to top speed to try and cool the system down, fails to do so, and the machine shuts itself down as a safety precaution.

Propping it up might have provided it with a bit more airflow, which may be why you experience the shut downs a little less frequently. I would invest in a can of compressed air, which can be found at any office supply store, and blow out the exhaust vents on your laptop. If you've never cleaned your machine before, dust and other debris that accumulates in the vents and around the fan have probably built up enough to restrict air flow.

Makes loud continual beeping noise after boot up and fan sounds very noisy


The beeping is most likely bad RAM, the fan running loudly may be a result of the system not being able to detect it's own temperature (which can also be caused by RAM if the system can not post correctly) or it could just be a dirty fan.

My Acer Aspire One AOA150 's fan is very loud and warm


I'd suggest that you carefully pull the base of your Acer apart - taking out the screw, and keeping track of them. See if your fan is dirty - I have an Acer as well, and if it's dirty, it get loud, and HOT!

A quick cleaning does wonders!

Acer Extensa 5630G it's overheating a lot!


Cooling pad will be best bet, extend the life of the laptop. They are annoying sometime but got to weigh options. Cooling pads plug into usb so that is a plus, dont have to plug them in wall. Try to find a real slim one, i got a real slim one, not the strongest fan but it keeps my laptop at a good temperature.
