Cooling fan

Laptop CPU and GPU fans

A CPU cooling fan is a dedicated fan which cools down the heatsink and eventually the CPU (Processor). Usually the CPU cooling fan comes as a part of the heatsink assembly – a metal part drawing heat from the CPU chip. In addition to the CPU cooling fan, some laptops have a dedicated GPU (graphics processing unit) fan which cools down the GPU chip.

The CPU and GPU cooling fans connect directly to the motherboard via a cable running from the fan. When CPU and GPU chips get hotter, the cooling fan spins faster.

COOLING FAN LOCATION IN A LAPTOP.

On some laptops the cooling fan can be easily accessed through a door on the bottom, as on the following Gateway laptop.

If you cannot find it on the bottom, then it’s buried inside the case, as on the following Dell laptop.

Cooling fan inside laptop

COOLING FAN RELATED PROBLEMS.

If your laptop feels very hot and shuts down without any warning, it’s possible that you have a faulty fan. Listen for the fan. Is it working? Sometimes you can see the fan through the fan grill on the bottom of the laptop. Can you see the fan spinning?
If the fan never starts, probably it is bad and has to be replaced.

When the fan bearing goes bad, the fan starts making grinding noise. In this case you’ll have to replace the fan.

If your CPU fan works hard all the time, most likely it happens because the heatsink is dirty and is clogged with dust and lint. You can clean the heatsink using compressed air.

    Hi there, I hope you can help.
    My laptop shuts down after running for about 30 minutes. It just turns off by itself like loosing power. If I restart the laptop, it works for a while and shuts down again.
    I can hear the fan working. What is wrong?

  2. Repair Man says:

    Anton,
    Try cleaning the heatsink. I think your laptop shuts down because it overheats. Make sure the heatsink is clean and there is no dust inside.

  3. Charly says:

    When I power up my notebook the fan starts too and I can hear grinding noise. I’m listening very closely but I cannot tell where the noise coming from. The fan is very close to the hard drive. I don’t know if I have a bad hard drive or fan. How can you tell?

    Remove the hard drive and start the laptop without it. If you still can hear the same grinding noise, apparently it’s coming from the fan.

    Thanks man,
    I had bad fan. Already ordered a new one from ebay.

  6. Anton says:

    It worked! I found a thick layer of dust inside the fan, fortunately it was on the bottom. I cleaned the fan with air compressor.
    Working fine now. Has been running for 3 hours already.
    Thanks for the advise.

    Sure. That’s a very common problem. Many laptops (different brands and models) suffer from overheating because of clogged heatsink.
    Keep it clean now.

  8. Jason says:

    I used my Shop-Vac to suck up all the dust. Works like new now and quite.

  9. Rifat says:

    When laptop stars it’s quiet but after about 5 minutes something starts making rattling noise and than it goes off. After some time stars again. Do you think its bad fan?

    I think so. Also, listen for the hard drive. Sometimes a faulty hard drive could make very similar noises.

    Hi there,

    My Dell laptop is dead. before it is dead, i suffered to reboot it, sometimes i have to tune power on a few times to get it booted, but once it is on, it worked ok. But finally, it can not be booted:

    when the power is on, LED lights on: sometimes all 3 on for a few second then off completely; sometimes only the light labled A is on for a few seconds then off. every time, the fan doesnt spin, but I noticed it worked before only when CPU is HOT.

    What is the problem!?

  12. Repair Man says:

    qian,
    It’s hard to tell what’s going on with the laptop from your description. Could be bad CPU, motherboard, connection related issue, etc…
    Did you check the memory module? Try reconnecting RAM modules. Do you have two RAM modules installed? Try removing them one by one. Not sure if it’s going to help, bu you can try.
    Did you test the laptop with another AC adapter? Could be bad adapter.

    This description:

    when the power is on, LED lights on: sometimes all 3 on for a few second then off completely; sometimes only the light labled A is on for a few seconds then off.

    Sounds like there could be a problem with the motherboard.

  13. CommTech says:

    Cleaning the fan/heatsink assembly is a good idea to prevent overheating but make sure you use compressed air. I used a vac and it has caused the fan to now make a noise – probably messed up the bearings or the fan is out of alignment. Guess I’ll have to replace it to get it silent again.

  14. Repair Man says:

    Cleaning the fan/heatsink assembly is a good idea to prevent overheating but make sure you use compressed air.

    Also, it’s a good idea to block the fan so it doesn’t spin while you are cleaning it with compressed air.

    There is no easy access to the cooling fan in an Inspiron 1526 laptop. The fan is mounted under the motherboard.

    In order to access and replace the cooling fan, you’ll have to remove the motherboard as it explained in this service manual.

    My cooling fan is not working well and i already clean it but I have to change it. My problem is that here in Portugal i can’t find and I don’t know where to find one for my Acer Aspire 1691 wmli. I search on several websites but there is a lot of fan that looks like the same. Can you tell me where can i order one safely? Thanks.

    Most likely there is more than one fan compatible with your laptop. Find a store selling spare pars for Acer laptops and ask them which fan is compatible with your model. They have an access to the list of spare parts and can tell which one you should use.

  20. Mike says:

    I have a Dell Inspiron 1525. When I bought the laptop back in December, a few weeks later I noticed that if the computer has alot or large programs running, the fan will begin to rattle like it is falling apart. If I turn the programs off, usually the noice subsides and it sounds like normal again. When I first had it, I recalled at times it would begin to rev up like a jet ready for take off. I haven’t heard this in a while. Now it is just the rattle. It will rattle around , then shut off I guess when it is cool again. Start up a few minutes later and rattle again. If I am just checking email or just have it running, the fan stays pretty normal sounding. I am not sure if this is something that needs to be addressed right this moment. I am pretty sure it is loose, a screw a bearing, maybe. If I am doing something that causes it to rattle, I usually try to finish what I do, but I am getting use to it and now start to ignore it , untill I have finished what I need to do on it. My question is, do you think that this is the bearing or something loose. I am sure I should replace it, and I do have warranty. I was going to just ignore the problem until it either failed , or when I get the desktop I want, then maybe send it in. I am definatley going to make use of the warranty and send it in before that runs up in december. So basically to the point. Do you think that this will cause any real problem , if I just continue to ignore it, It is running, but it makes the rattling sound. SO I am not really sure if it is adequately cooling down my system. Thank you for your time.

    Mike,

    I noticed that if the computer has alot or large programs running, the fan will begin to rattle like it is falling apart. If I turn the programs off, usually the noice subsides and it sounds like normal again.

    The cooling fan can run at a few different speeds. Apparently the bearing is failing and the fan rattles at the highest speed.

    Now it is just the rattle. It will rattle around , then shut off I guess when it is cool again. Start up a few minutes later and rattle again.

    I guess the bearing is getting worse and now the fan rattles at all speeds.

    do you think that this is the bearing or something loose.

    To me your description sounds like a failing bearing.

    Do you think that this will cause any real problem , if I just continue to ignore it, It is running, but it makes the rattling sound. SO I am not really sure if it is adequately cooling down my system.

    It might cause a real problem if the fan fails completely, you can fry the CPU.

    I currently use I8kfanGUI software to control my laptop fans, it says i have 2 fans. However, only 1 of them seem to be working, the other sometime on sometime off, and whenever i try to play a game that require heavy graphic one of the fan run at max speed, the other is off…Is there any way that i can control the second fan ?

    If possible can you show me where the GPU fan is, on Dell Laptop?

    If the laptop doesn’t start when it’s cold, most likely it’s not related to the cooling fan. The laptop still should turn on even if the fan failed. I think your problem is related to a different component.
    Does your laptop get any power if you plug in the power adapter and push on the power button? Is it completely dead or just will not start?

    I think it’s normal. Right now I’m typing on a Toshiba Satellite A135 laptop and my cooling fan turn on and off about every 10 seconds. I’m in a 72 degree room.
    Try cleaning the heat sink with compressed air. Maybe the heat sink is clogged with dust and cleaning it will help to keep the CPU cooler and the fan will turn on less often.

    If the cooling fan works fine but the laptop still shuts down because of overheating, it’s possible that you have to replace thermal grease between the heat sink and CPU. Maybe thermal grease dried out?

    I don’t think so. The laptop should start even when the battery is removed. Remove the battery and try turning it on. Does it start when the battery if removed? If not, the battery is not your problem.
    You can try minimizing the system as much as you can. Remove the hard drive, optical drive, disconnect the LCD screen, etc… Leave only main components such as motherboard, memory and CPU. If the laptop still doesn’t turn on, most likely there is a problem with the motherboard as you said CPU and memory is OK.

    I believe you cannot use PCG-3C2L number for finding spare parts. There should be another number somewhere on the keyboard cover or screen bezel. It also could be PCG-XXX or VGN-XXX number. Can you see it on your laptop?

    I think it’s possible but you have to have some soldering skills. Also, you have to know how to use a multimeter.
    I think you can remove the motherboard and using a multimeter find where you can solder the fan directly. It’s will be on as soon as you turn on the laptop.
    Where to solder the fan? I don’t know. All motherboards are different.

    Most likely the laptop shuts down because of overheating. It happens because there is dust stuck inside the heat sink and cooling fan.
    In most cases you can clean the heat sink assembly with compressed air.
    Buy a can of compressed air or find an air compressor and spray air into the intake on the button until all dust is gone. Test your laptop now.

    That’s true. In most laptops the cooling fan turn on only when the laptop is getting hot. But if your laptop shuts down by itself when hot, something is wrong.
    Usually it shuts down because of overheating, when the heat sink is clogged with dust OR the cooling fan doesn’t work.

    My Dell latitude D600. My laptop overheated and shut down. Tried to turn it back on and it wouldnt come on. Found your site and opened it up omg no wonder it over heated. The question is, since it wouldnt come back on, is there more going on? Meaning did it fry like the motherboard or something else? I have cleaned the fan and heatsink. And I have no issue replacing the parts that need to be replaced. I just dont want to replace them and still not have it work because something else was damaged. So, is there a way of testing the system to see if it will come back on?

  56. Repair Man says:

    Laura Taylor,

    The question is, since it wouldnt come back on, is there more going on? Meaning did it fry like the motherboard or something else?

    Yes, it’s possible you have another problem but I cannot tell what’s going on without looking at the laptop.
    In order to start your laptop with video, you need only three main components: motherboard (with video card), processor and memory. If you cannot start the laptop with a known good AC adapter, there is a chance that one of the above mentioned main components is bad.

    Try reconnecting memory modules. Try removing memory modules one by one and test the laptop with each one separately.

  57. canuck says:

    I own MSI laptop with intel duo processor. Every 9-10 monthes I face the same problem- CPU fan stops spinning. So every few months I take my laptop to MSI representative and pay them to fix it, they finish the procedure in less than 10 minutes. The procedure consists of opening the case of the laptop, and removing the dust from the heat sink (this is how they explained it to me). Yesterday the same thing happened again. I decided to fix it myself. I opened the case removed the dust from everything I could, but the fan continued to be still. I brought it immediately to MSI representatives and they fixed problem once again. The reprsentative told me that he just put a thermal grease between processor and heat sink. He also admitted there was no dust inside the case. But then they had put the grease there 10 months ago! I suspect that they are not informing me completely about what exactly they are doing to fix my laptop, they know that it’s simple enough that I could do it myself instead of paying them money every few months to do it. For example they could be entering the BIOS setup and changing something (BIOS is responsible for initial fan spinning), I would be so greatful if anyone could tell me any related information to my problem.

  58. Michael says:

    It would be really handy if someone published a list of which laptops have easy access to the CPU heatsink for dust removal by removing a small cover, verus which laptop models require removal of the keyboard. Then we could buy accordingly.

    If the fooling fan works and heatsink is clean, it’s possible you need to replace thermal grease between the heatsink and CPU.
    Maybe thermal grease dried out and not working properly.

    Maybe use the cooling pad?

    Most likely it’s either bad memory or motherboard failure.
    Try removing memory modules one by one. Test the laptop with each module in either slot. If the problem doesn’t go away, most likely this is motherboard failure.
    Pavilion dv9000 has a known problem with the motherboard – video chip failure.

    What is not running now? The fan doesn’t spin or the laptop doesn’t turn on?

    Your laptop is not a common one. I don’t know the fan part number.
    Maybe you can find a compatible fan on ebay.

    I took apart my laptop earlier today. I feel like a bad nerd for neglecting it, but I’m a software nerd, not a hardware nerd. I have a Toshiba, and these laptops are well known for CPU fan issues. Mine was just dirty, and now my computer is running beautifully again. I did not use your site to help with that (didn’t run into it via Google), but I want to read your site for my new love and hobby: repairing computers. It was awesome, I might be converting to a hardware nerd (or both). Thanks for all the awesome information on your site :). I ran into it via Google images, searched for “heat sink”.

    It depends on the laptop model. Maybe you can do it yourself. What is your laptop model?

    can i get away with a laptop fan pad for a few weeks until i can get someone to replace it? i have an HP Dv7 and the fan is hard to get to.

  75. Repair Man says:

    rookie,

    can i get away with a laptop fan pad for a few weeks until i can get someone to replace it?

    What’s going on? Is is noise or stopped working completely?
    You shouldn’t use the laptop with a failed fan because you can damage the motherboard. The cooling pad will not help if you have a failed fan.

    i have an HP Dv7 and the fan is hard to get to.

    You can download service manual from HP website. It has disassembly instructions.

    Isaac,

    my laptop gets hot and the fan spins and stops and it spins.what is the problem?

    If the laptop gets hot try cleaning the cooling module. Probably the heatsink clogged with dust.
    Try cleaning the heatsink using compressed air.

    I guess it depends on the cooling fan installed into your laptop.
    Does your fan has any sticker on the top? Can you find any fan part number?
    If you can, google it or search on ebay. Most likely it doesn’t have to be a specific fan.

    I wanted to thank you for the article, it saved me 199 plus shipping to send my Gateway Laptop T series to service. My laptop was excessively overheating, and shutting down. I did a cleaning of it a few months back generally, afraid to take the fan compartment off, as Gateway support had said not to clean within the laptop on their support pages. So the problem of overheating wasn’t solved on my first attempt. After talking with support, and finding that the cost would be absolutely too high for me to afford on getting my laptop serviced, I figured I couldn’t do much to hurt the situation, and started researching how to on the internet, thus I found your site and read some of the remarkable statements of others that followed the instructions you recommended. Last nite I got brave, took the computer’s back off, checked it for any damage, loose cables, etc, vacuumed it out, and then decided to get even braver and take the fan cover off and explore under it. Oh, wow, glad I did, the dust accumulated on the fan’s vent area was really gross and cumulated to what looked like a good 1/4 of an inch. So I cleaned! and vacuumed again, put back together, and my laptop so far is running smoother, quieter, and not getting extremely hot. My fan seems to be running nicely as well. Thank you for saving me a bundle of money on cost to get my laptop running again. I appreciate it!

    I have a Toshiba Satellite L450. I accidentally hit it against a door (not that hard!) when I was leaving a room in my house yesterday and bringing it with me. It’s been making noises ever since, although if I change the angle of the computer, the noise stops. Is it the fan? I have 2 weeks left in the semester (so I need my computer here), so I was wondering what I can do until I can take it to get repaired?

  82. Nikki says:

    My gateway kept over heating so I followed your instructions and not only did it not overheat but the fan ran quieter. thanks so much for this article.

    You are welcome.
    Now you can keep your fan clean by spraying compressed air into the fan grill once in a while.

    MOST COMMONLY YOUR LAPTOP WILL SHUT OFF .THE FAN BLOWS AIR TO THE HEATSINK TO KEEP IT COOL AND 9/10 BETWEEN THE FAN AND THE HEATSINK IT GET CLOGGED.OPEN UP AND CLEAN THE FAN AND REPLACE COMPOUND WHICH WILL NEED REPLACED DUE TO EXCESSIVE HEAT.NOW YOUR LAPTOP SHOULD BE GOOD A NEW.

  89. DARREN says:

    OPEN IT DONT SPRAY COMPRESSED AIR BECAUSE THE DUST GETS SO BAD IT LOOKS LIKE A FILTER U NEED TO PHYSICALLY REMOVE IT AND UR ONLY BLOWING DUST TO OTHER PLACE RESTRICTING AIRFLOW

    @ DARREN,

    OPEN IT DONT SPRAY COMPRESSED AIR BECAUSE THE DUST GETS SO BAD IT LOOKS LIKE A FILTER U NEED TO PHYSICALLY REMOVE IT AND UR ONLY BLOWING DUST TO OTHER PLACE RESTRICTING AIRFLOW

    This is true with some laptops. Sometimes the dust builtup is so bad that it have to be physically removed.
    If you decide to clean up the cooling fan using compressed air, blow it into the fan so the dust gets out from the side.

  91. Repair Man says:

    OPEN UP AND CLEAN THE FAN AND REPLACE COMPOUND WHICH WILL NEED REPLACED DUE TO EXCESSIVE HEAT

    If you decide to replace thermal compound, make sure to have it before laptop disassembly.

    I have a Toshiba Qosmio x505, its not even two years old yet, and its got some serious overheating issues.
    I chose to send it in to toshiba 2 months before my warrenty Expired and they sent it back after 4 weeks saying absolutely nothing was wrong. Everyone who looks at my computer can tell somethings wrong with it that it shouldn’t make the noise it does, but no one can pin point it. Some say it might be a heat sync problem, since the fan is still running, others say its just the fan.
    My main issue is I cant figure out where to get another heat sink for it…does it have to be the same make and model? I am very lost at what to do, and it gets terribly cold having to keep a real fan on my laptop to keep it cool while the fans struggle to keep it from being hot.

    Hi Repair Man, I have Toshiba Satellite A135-S7404 that when I power it ON the fan will spin and stop after few seconds. This cause my laptop to sudden shutdown due to hot CPU. Is this a fan problem that can be repaired or need fan replacement or this is a fan control problem? I already used compress air to removed dust. Thanks for information to be provided.

    my fan on my lap top was making noise I cleaned it with compressed air now just hot air is coming out I can barley here the fan why?

  97. Repair Man says:

    @ Richard,
    Does it spin? It’s possible the fan was on the verge of failure and cleaning killed it completely.

    Pls i need serious help, my Toshiba Satellite L655-S5107 is giving me problem.
    The last time i used it, it worked perfectly and i tried putting it on again only that the fan rolls 1 or 2 secs with the led light on and all go off again. If i tried using battery alone the battery led (red) just blinks four times and at a point the when the AC and battery is in it will just continue to blink the power led, but most thing is the fan rolls and stop immediately, i had tried removing battery, press and hole d power botton for 30, 60 secs, removing hard drive, reinstalling memory sticks etc etc, but i cant really open my laptop case cos sth seem to be holding it down.

    Pls i am fed up what do i do? Urgent help pls cos i need it for presentation
