I think you were on the right track with overheating. Many laptops have more than one set of input and output air vents. Maybe you cleaned out one but missed another one. Since you said the laptop turns off when you place it on the floor I'd look for partially clogged vents on the bottom of computer. Brush away any external dust on the vents with an old toothbrush. Then try blowing air through the vent holes with one of those cans of compressed air made for dusting off keyboards. Sometimes the dust is buried inside the machine. I once worked on a Sony laptop that I had to take apart to completely clean out the vents.

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.

How to prevent laptop and Deskto from overheating.


overheating[overheating]"overheating""best computers""computers laptop"


First of all you need to keep your work space clean at all times so that dust and debris do not get into your unit.

Also you need to maintain airflow a routine maintenance of your machine will keep the unit in order.

If you computer is overheating first thing you do is open the case and clean out the dust.

Also you need to replace the Thermal compound under you heat sync where you cpu is.

  1. First you want to do is take off the cpu fan.
  2. Then you want to wipe the access thermal compound off.
  3. Then you apply the thermal compound by adding one dime size drop in the middle of the cpu (do not spread with fingers)
  4. Then you want to put back on your fan and heat sync.
This will keep your system at normal operating temperatures I would suggest you do this once ever 3 months at the most.

If the computer detects overheating or fan failure it will shut down automatically. If you replace the fan you should be fine. Remove your old fan and try to get one that connects the same way, some of them connect directly to the heat sink, others to the motherboard.

In the control panel, there is an icon for power settings. Set the fan for maximum cooling. Make sure the exhaust ports on the computer are blown out. Don't use the computer on a soft surface.
