Hey mars bar,

One of the most common reasons why a CPU or case fan will malfunction is due to built-up dust and debris. If a fan gets clogged with dust, not only can it stop spinning entirely but it can also cause internal components to overheat due to lack of proper ventilation.

Generally the simplest way to resolve this type of issue is to open your computer case and clean the interior using a compressed air disposable duster. It is important to remember though that such dusters are not designed to be used for prolonged periods and instead are meant to be used in short, sporadic bursts. Additionally, you will want to make sure that the can is held at least six to eight inches away from the surface being cleaned, as compressed air can not only leave liquid residues behind but also may freeze surfaces if they are held too close.

In the event that cleaning doesn't resolve the issue, there is a possibility that one or more internal components may be in need of service/replacement.

If you are unsure how to proceed, I would strongly suggest speaking with your local computer repair technician or a Geek Squad® agent at your local Best Buy™ store for more information.

Hope this helps you out.

Sincerely,
Aaron

First try to clean all air vents with canned air, if still overheating clean interior, redo heatsinks, check secondary fans.

As you look into the vents, you may see dust build-up on foil radiators or heatsinks, not to mention on the fan assembly if it is visible. Depending the the size of the vents, you may be able to loosen up and capture some of the dust with Q-tips (cotton swabs) and **** it out with an electronics vacuum, but most technicians head straight for the compressed air. I'm not a huge fan of using compressed air to clean laptops without taking them apart, because while you'll definitely blow the dust off whatever you aim at, you'll often be blowing it somewhere else in the notebook. The immediate result will be a cooler running notebook because dust and lint build-up on heatsinks can act as a blanket, keeping the heat from being radiated and convected away, but if all you've accomplished if throwing that blanket over some other hot components that aren't visible through the vents, you may have greater problems in the future. Make sure you use a canned compressed air sold for cleaning electronics, otherwise there may be harmful propellants or liquids mixed in. Read the instructions, and if they tell you to always hold the can upside up, be careful to obey, because holding it upside down may result in squirting liquid

Acer fan wont turn off


Is the computer starting up ?

Computers allow us to connect with people from around the world, and successfully complete school and business work. Unfortunately, technical issues can arise after prolonged use of a computer or due to manufacturer issues. A computer fan that runs all the time can be from your personal habits when using your computer. Fortunately inexpensive steps can be taken to resolve the matter.

ventilation b> If you are using a laptop computer in your lap or on a cloth for an extended period of time, your computer may be overheating, causing the fan consistently run. Since the computer has little insulation between the surface and the motherboard, the fan stays on. Purchase a cooling pad for the laptop. It can be found at your local office supply store. If you don't want to buy a cooling pad, you can periodically lift your laptop up and sit it on a desk, countertop or another flat surface. If your desktop is overheating, it could be because it is in a small area with little ventilation. Ensure your desktop is in an area that allows air to circulate. How to Properly Clean Your Desktop Cooling System & Fan http://www.youtube.com/watch?v=GgOaIJ82gFM b> Dust b> You computer fan may have accumulated a lot of dust, which causes the fan to run continuously. Purchase compressed air and periodically spray the computer fan to loosen up any dust that may have accumulated. Most computer fans are exposed, so accessing the fan should not be a challenge. Technical issues b> In some cases, your computer may have either a defective fan or thermostat. Computer providers, such as Dell, allow you to purchase a new fan and replace it yourself. For thermostat issues, you may have to contact a computer repair professional for assistance. Computer is overworked Depending on the age of your computer multiple programs that are running can cause it to overheat. Watching a lot of DVDs, playing video games, and listening to music on your computer also can cause overheating. Considering closing some of your programs and rebooting your computer. Check you CPU make sure its securely seated and has thermal grease http://www.hardwaresecrets.com/article/Thermal-Compound-Roundup-February-2012/1490 Viruses or spyware b> Spyware can continuously run on your computer, causing the fan to overheat.

SYSTEM TRIES TO COME ON BUT ONLY MAKES IT TO THE CONFIGURING SCREEN THEN IT SHUTS ITSELF BACK DOWN, THIS IS CONTINUOUS. I have a Dell Inspiron 531. Please advise. Thank you, Candace


It sounds like it could be a problem with overheating, which is causing the machine to turn itself off. Try opening the side cover, and carefully cleaning the motherboard and especially the CPU fan - which is the large fan probably on top of a silver box with loads of fins on it. Carefully remove the dust, and see if this clears up the problem. It may be worth removing and refitting the memory whilst the computer is open, to reduce the problems of bad connections between the cards.

If it doesn't fix it, then reply here with any error messages that pop up on the screen.

CPU fan failure causes system to aromatically shut down..


Without a proper working cpu fan the cpu will overheat and shut the computer down... if not fry the cpu. You will need to replace the cpu fan and hope the overheating didn't mess up the cpu or something on the motherboard.

Assuming that you are correct about being malware free, my next best guess is that the machine is overheating. Overheating can cause a PC to slow down. A simple way to help with an overheating PC is to clean all dust from it, especially dust stuck in the fans and on the CPU heatsink.

VAIO CS36 fan problem


You got an overheating issue and your fan keeps kicking on to try to cool the computer down.  Make sure you don't got this thing too close to a wall and make sure the vents are not blocked.  You should also download new power management firmware updates online and reflash the BIOS.  You also should get a new fan cause the current one is probably fu.k.d up.  Give that a try old chap.  Cheers.

Gateway FX400S power failure.


I think you are right. There is an overheating problem. The questions are, what is overheating and why?

Dust is the single most common cause of computers overheating. Dust on fan blades can reduce their cooling capacity by large amounts.

Dust can also cause premature failure in cooling fans. You may have a "dead" fan in there and you don't know it yet.

The trick for you would be (if I was investigating, this is what I would do) remove the cover (assuming this is a desktop or tower) and turn it on. From here you can visually see which fans are moving and which are not.

Exception is the power supply fan; which is sometimes inside the power supply casement.

A can of forced air may help here, but try not to breathe that stuff.

good luck

Hp Pavilion zd8000 shuts down loosing all opened windows


There is a software called "SpeedFan" which you can download here

This software will tell you the internal temperatures of the computer (so you can figure out if overheating is the problem). Most of the time overheating is due to excessive dust inside the laptop. The best bet is to get a can of compressed air and clean the inside out. This does require some disassembling of the system, so if you are not comfortable doing so I would advise you to take it to a local computer shop.

Another solution would be to purchase a "Laptop Cooler", this will lower your temperatures anywhere from 5-10 degree's, but can get annoying to lug around with you. You can view some laptop coolers here

If you happen to run the Speedfan application, let us know what the temperatures displayed as, and I can tell you if it is running too hot!

My hp pavilion a800n's fan won't turn off


It is possible that your computer is simply overheating causing it to slow down. There are a few ways to check this. Enter the BIOS and go to the hardware monitor, what temperatures does the computer read both for the CPU and the Motherboard? Another option is to install and run a program called HWmonitor that can be found here. Report back when you can.

Overheating and sporadic shutdown - does this follow screen freezes and fan stopping?


I would suggest you have the fans/heat sinks cleaned as soon as you can. it is most likely shutting down because of heat (thermal shutdown). on some laptops the fan doesn't come on till close to melt down (my inspiron laptop is great for that). If you are at uncomfortable with taking the bottom of the laptop off to clean out the dust and dirt from the fan take it to a shop and have it done.
you may want to invest in one of those laptop chillers... basically a stand with fans on it. they make usb ones that get there power from the usb connection. abit ruff on the battery if you are not using a/c but better then replacing the cpu.
