Only do this if you feel competent in doing so.

Pulling apart laptops is not for the faint of heart.

If you really must do it there are some good guides here.

An alternative is to get a can of compressed air used to clean computers. Put the nozzle on and spray it in every hole you can see without putting the nozzle itself inside the laptop.
Do this outside with glasses on.

    Thats because there are hidden screws.

    You also have to remove the hard drive and ROM drive.

Unfortunately, like all fans, the ones in your laptop will eventually end up covered in dust and dirt, and that could spell trouble.
so follow the proper method to clean your laptop.
What you'll need:

  • Hardware: Torch, can of compressed air, microfibre cloth, small Phillips head screwdriver, glass cleaner, and lint-free wipes
  • Software: Microsoft Windows
Step 1: Keep your cool
Computer components -- processors, graphics cards, and the like -- get hot when they run. To mitigate this, laptop makers put in elaborate heat sinks that absorb the heat generated by the processor. In addition, all but the tiniest models have at least a single fan; some bigger systems have two or even three. When the temperature rises above a certain level, the fans automatically come on to keep the laptop out of the red zone. Unfortunately, like all fans, the ones in your laptop will eventually end up covered in dust and dirt, and that could spell trouble.
An occasional cleaning will keep your laptop fans spinning effectively for years. But before you can clean them, you'll have to find them. Fortunately, in most cases, they're near the vents that are located around the edges of your case; these slats let cool air in and hot air out. Don't worry if they're covered in dust and lint, we'll get to that. Now you'll need to open up the laptop case.
Look for a few sets of screws, underneath the laptop near the vents. Remove the panel and look for the fans -- they're circular and plastic, usually about the size of a 10c piece, with a small propeller inside. Again, it may be covered with dust and lint.
Step 2: Dust bunny patrol
Now that you're inside the laptop, use a torch to look around for built-up dust and dirt. Using the eraser-end of a pencil or tweezers, pick off any nasty deposits you come across.
Start at the fan, then work your way to the ducts and vents. Look under the ribbon cables, around the hard drive, and near the tiny circuit boards. Grime can hide in the oddest places, like the processor's copper-coloured heat sink, so make sure you explore all the laptop's nooks and crannies.
Step 3: Air it all out
You've done the detail work, and now it's time to go big. Put on a dust mask, if you have one. Grab the can of compressed air and spray down the inside of your laptop. Go nuts. Blow out all the dust you can find. It won't be pretty, and you might want to have a vacuum cleaner running nearby to grab all the junk it as it comes out. Don't be surprised if a lot comes out of that little laptop.
Step 4: Shake, rattle, and roll
Now that you've made your first pass at cleaning out the inside, give your laptop a little shake to dislodge any particularly resilient dust and grime. Keep cleaning and shaking until nothing more comes out.
Step 5: Key to the crumb highway
Now that the inside of your laptop is as clean as a whistle, it's time to tidy up that nasty keyboard. Don't be embarrassed by what you find: Most keyboards have enough crumbs to feed a flock of pigeons for weeks. Use the can of compressed air to blow it clean, but be careful not to break any keys off.
Step 6: Tighten up
While you've still got the laptop open, give each of the major components a quick look to see if any are loose. A loose motherboard or hard drive can cause damage in the long run, so make sure all of the screws are tight and all of the cables are well connected. When tightening the screws, be careful not to overdo it -- gently tighten until you feel some resistance. When you're done, reconnect the access panels on the underside of your laptop.
Step 7: Clean your screen
All laptop screens are susceptible to nicks and scratches, and the latest glossy, high-contrast displays show off fingerprints that even Columbo couldn't miss. We like to give our screens a quick rubdown about once a week. You can use any brand of window cleaner so long as it doesn't contain ammonia or any harsh detergents. We're partial to Sprayway, because it gets all foamy and doesn't leave annoying streaks; unfortunately, Sprayway can be hard to find in some places, and you may have to make a special trip to a glass or mirror store to find it.
When wiping down the screen, stay away from tissue that leave lint behind or rough fabrics that may scratch the display. We recommend lint-free cleaning cloths, a soft cotton chamois or a microfibre cloth.

Having had 4 Acer Aspire Notebooks I am confident of my answer to this question. Using a small Phillips head screwdriver, take off the largest back panel on the bottom of the computer.

You will then see the cooling fan as well as other components that are exposed. Use a can of compressed air or a computer vacuum kit on a regular vacuum and blow off the dust or vacuum up the dust that collects on the fan and components.

Once there is no dust left, close the computer by replacing the panel and tightening the screws you removed. Also look for any thing that could be making contact with the fan that might be causing the noisy.

Hope this helps. You should also consider a small dish or box to put the tiny screws into when they are removed. They can fall and get lost easily.

SOURCE: noisy fans laptop overheating?

The only safe way to clean the vents is with compressed air. I don't know how old your computer is but when the fan starts making noise and overheating then it is time to replace the power supply. Continued use may destroy your CPU cause of overheating.

SOURCE: The fan runs constantly and gets really hot.

You may be running too many programs in the background which can heat up a processor pretty well. You may also have a virus which overtaxes a processor. Also, always make sure that the heat vent in the back of the pc is well vented and not obstructed, and NEVER have the pc placed on something like a bed, blanket, or pillow
OK, Do this;
These are the steps that you need to take, and the instructions on how to do it:
1. Reboot into Safemode
2. Run a virus and spyware scanner while in safemode
3. Defrag
4. Scandisk
5. Registry error repairing while in safemode
6.Reboot into regular mode windows

Here is how to do it:
Reboot yor machine while holding the F8 key right as it boots back up. A menu will apear. Choose -->"start windows in safe mode with networking".
Windows will start in safe mode. Run an AVG virus scan, then run Defrag by exploring your computer, right click on C: drive, click PROPERTIES, then the TOOLS tab, click the "check now" button, and only checkmark the top box 'fix file system errors', then click ok, the computer will then tell you it will scan upon next reboot., Now click the DEFRAG NOW button. the choose defrag. After Defrag runs for about an hour and it is finished, restart the system. If is still won't run normally, go back into Safemode buy pressing F8 on reboot, then run a registry fixing program such as uniblue registrybooster, then reboot again. If it still won't run right, you may want to reinstall Windows and see if that works. If reinstalling windows doesn't fix it, it may be a hardware problem.
PRINT THESE INSTRUCTIONS AND KEEP A COPY NEAR YOUR SYSTEM FOR FUTURE PROBLEMS. THIS SERIES OF STEPS CAN FIX MANY PROBLEMS
Good luck.
James.

HP dv6810us laptop fan too noisy? Any solutions?


Hello,

Here is a simple guide to cleaning your laptop fan if your are comfortable opening the computer.

http://www.rightinfonow.com/laptop-noise

If not it is most likely that the fan is clogged with dirt and dust and just needs cleaning. If blasting it externally with compressed air does not work you or a local tech will need to open the computer and clean it.

Thanks

Very noisy fan


Make sure that the fan is running properly & that the air ways are not blocked.
You can blow compressed air into the cooling vents of the fan. If you notice clouds of dust coming out, then it might be a good idea to disassemble the laptop, clean the fan & air ways, & reassemble it back. If the fan has failed & is no longer running, it might need to be replaced.

Noisy Fan in my Dell Inspiron 9300 Laptop


Get a can of compressed air used to clean computers.

Put the nozzle on and spray it in every hole you can see without putting the nozzle itself inside the laptop.

Do this outside with glasses on.

laptops should never be used on soft surfaces eg carpet, beds, cushions, etc. Most newer laptops also have more cooling slots / openings. this leads to a fater build up of gunks inside..

Best option is to buy a GOOD 3 fan notebook cooler.

If you are comforatble opening the laptop then that is a better option for cleaning but if not a good laptop repair shop could do this quite cheaply.

It is a common issue with newer laptops

My fan makes so much noise especially when i play video.Can someone help


The problem with fans is there really isn't much you can do with them. Normally they begin to make noise as the bearing assembly begins to wear, or it might just need to be cleaned. In either case you need to crack open the case on your laptop, then you can inspect the fan. You can try cleaning it at that point, but usually its easier just to replace it. The reason why it makes more noise when you play videos is because video media requires more system resources to run, which also generates more heat. So, while you have your laptop open you may want to check your video card (which should also have a fan) and make sure that its clean. A dirty video card will **** out a lot earlier than it should.

SONY VGNFJ270 LAPTOP BECOMES HOT AND GIVES LOT OF NOISE


If the fan is noisy and the laptop is running hot, then most likely the fan is faulty and spinning slowly. Therefore the fan is not providing sufficent air flow to cool the laptop's CPU. The fan needs to be replaced and possibly the heatsink assembly needs cleaned to remove dust buildup.

Sony Vaio laptop fan is very loud and continously running


My pcg-k33 was very noisy (fan) so I vacuumed the fan opening with a powerful shop vac. This helped alot. I think that the CPU temperature triggers the fan so keeping the cooling system clean is important. As well, there are openings on the bottom for air so it is important to keep the unit on a surface that doesn't impede airflow (on your lap is a bad idea)
