Under load the fan will kick in and stop as the temperature gets hot. This is normal.
If it is doing this on a reguar basis, you can do the following

1.) Download a copy of a hardware monitoring tool (everest is good) as a trial, note the indicated temperatures that appear on the toolbar, up to 60 degrees is ok under load, after that, you have an overheating problem.

2.) Either take the laptop to a shop and get it cleaned out (dust and dirt accumulate in the fan and coooling matrix), or try this yourself. You can try vacuuming the intake and outlet ports for the fan, but this is not the best solution.

3.) Obtain a USB cooling pad, these are ludicrously cheap on the lies of ebay at less than £4.00 delivered from some suppliers and reduce operating temperatures by 15-20 degrees if placed correctly

I have an acer aspire ax5900. The video card fan vibrates loudly for the first 10 minutes after start up. I am told I need a new video card. Is this correct and where is the best place to get one?


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 Fix verheating Computers?


Let's talk about how to fix overheating computers. If your computer is overheating, there's a few simple things you may be able to do, to help alleviate the problem. Sometimes, even on a brand new computer, if it's running and functioning completely perfectly, it may still overheat, depending on where it's actually placed, in your home or office. A lot of times if it's placed in a small, compact space, where there's not a lot of air flow around it, for instance underneath a desk, or to the side of a desk, up against a wall, or even sometimes next to a window, where sunlight is allowed to come through the window, and hit the computer directly. Those are things that can cause the system to overheat, that aren't actually problems with the system itself. It's just a question of placement. For those types of scenarios, I would take the computer, and place it in a more open space, or place away from windows, and get it to where it can solve the overheating problem on it's own, just by simply moving it. Now, if that's not your case, and your system is overheating, and it's in an open environment already, then I would take a look at the system. If you turn the computer off, and remove the side panel, or case off of the computer, to take a look at it. You can observe, once you turn it back on, if there's any fans inside, that aren't spinning or aren't turning, or if there's a fan that you can notice that's spinning very slowly, you can determine that that fan is probably going out. Most of the time, if a fan is going out, it will make a noise, as well, almost like bicycle spokes, with a playing card on them. If you've determined that one of those fans inside the computer is bad or faulty, then you can simply replace it, by taking it to a local computer store, or by purchasing the fans from a local electronics or computer store, and replacing the fan yourself. Also, if your fans are spinning fine. You've got it in an open area, but for some reason it's still overheating. Then, the approach I would take, is to add fans to your computer. There's normally a place on your computer, to add what they call a Secondary Case Fan, or even a Third Case Fan. You can purchase these again, from a local electronics or computer store, and add that fan to your computer, for normally five to twenty dollars. That's the best way to fix an overheating computer."

My laptop is overheating.




That would be normal, as the variable speed fan comes on only when the computer is under load.

What is not normal is that the fan is not coming on when the computer overheats.Or that the fan is not cooling enough when computer is overheating.

Monitor computer temperature using a software, check if Fan is coming up when temperature gets critical.

If fan comes up but does not cool enough, then replace the fan, it is not efficient anymore because of a bad bearing or dust. ~Also ensure that fan is well mounted, if fan has poor contact with CPU surface , cooling will be poor.

If fan does not come up, and critical temp is not detected, then the sensor on motherboard is bad, this is very uncommon. When this happens the problem is usually related to system or power settiings , rather than overheating.

If fan does not come up and temp is critical, then fan is faulty, replace it.

There are also more than one fan on many laptops, check that one of the fans (CPU fan, video fan) is not completely ded, and therefore cause for the problem.

By using the software below you can also find out if the problem is really overheating. If temperature results within normal range, then usually it is not overheating.In that case test systtem and check power saving settings.

Here is the software to control your fan and temp. sensor state:

Car overheating


First confirm that the engine IS actually overheating - steam, no heat to the interior etc. Sometimes a temperature sensor will fail and give a misleading 'overheat' reading on gauge. For that matter sometimes the gauge can fail and give the same misleading reading. Check that the cooling fan comes on when the engine temperature starts to rise above 'normal'. If not check (in order) fan fuse, fan relay, fan sensor, fan. Real overheating is caused by a lack of coolant AND/OR lack of coolant flow. Modern cooling systems are 'closed'. In other words there should be little or no loss of coolant. If the level is significantly low you have a leak....either external or internal. With the coolant topped up to the correct level and the radiator cap on, run the engine and look for visible leaks...hoses, valves, radiator etc. Internal leaks, eg. head gasket will usually be accompanied by white exhaust smoke (steam), hard starting, rough running and bubbles in the expansion tank. Sometimes, though NOT always, you will find the engine oil has a milky look and/or engine oil will be mixed in with the coolant.

The laptop was operating normally and some of a sudden it turned off. I haven't been able to turn it on again


Normally this happens due to the overheating of the CPU. If it is not the case then try recovering using window disk. Sometimes virus cause such problems.

Possible overheating


The PS3 has an automatic feature to shut down the system once it acquires overheating. The fans installed vary on how much heat is being generated by the system to cool it down. If the screen freezes occassionally try to set the resolution to a lower setting, say downscale from 1080p to 720p as it will make the system's work a little bit lighter and generate lesser heat. Hope it works.
