I saw this on PC Advisor and thought you should see it too. Like PCs, laptops use fans to blow air on components that would otherwise overheat. Typically a laptop will have one or two fans cooling the main processor and graphics chip or chipset. Many designs use a so-called heatpipe system to draw heat away from these components, with a single fan cooling a heatsink which is attached to the heat-pipes. The heatsink will have lots of 'fins' to dissipate the heat, and dust can also build up between these fins, reducing cooling power enormously. What you need to know is that the fans in a laptop are even more critical than in a PC. With everything packed in to make the laptop as slim as possible, there's very little room for airflow. And that means that even small amounts of dirt and dust can hamper a fan's effectiveness. The first signs of a clogged up fan are random Windows crashes as the system overheats. Or, if the vents are blocked with dust rather than the fan blades, you'll notice the fan running constantly or at a high speed than usual.

You can try various techniques, with the easier methods having a lower success rate. If you're not confident using a screwdriver to dismantle your laptop, grab a can of compressed air or try a camera lens air duster if you have one. wood floor steam vacuum cleanerVacuum cleaners are not recommended: they're quite ineffective at removing dust and they can also cause a build-up of static electricity which you don't want around a laptop.best way to clean moldy car seats Obviously make sure the latop is powered off before you start. best cordless vacuum cleaner ukInsert the nozzle of the air duster into the vents (or as close as you can get it) and start blowing the dust out. buy dryer vent cleaning kit

Try and stop the fan blades turning using a long plastic object - you'll have a hard time removing dirt from a spinning fan. For those that are happy to wield a screwdriver, turn off the laptop, flip it over, and remove the battery. If there is one, remove the plastic or metal panel in the base and hopefully it will reveal the fan. vacuum cleaner sale nzYour success here will depend entirely on your laptop model. best upholstery cleaner for microsuede couchIf you don't see the fan at all, you'll have to go one step further and remove other parts. There are many YouTube videos that show how to take laptops apart: just search for your make and model.The best way to do this is with a can of compressed air. If using compressed air, press the button in short bursts from lots of different angles.

Don't get too close with the nozzle and stop the blades moving as per method 1. You'd do well to unscrew or otherwise remove the fan at this point and check for any other dirt clogging up the heatsink or air vents. After you've blown out all the dust, replace the panel and battery and you should find that the fan runs much quieter when you power the laptop on again. The plastic bearings in laptop fans don't last forever and if your fan is emitting a loud whine (which it didn't when you first got the laptop) it's probably time to replace it. Here, ebay is your friend. It helps if you have a popular make of laptop: we found a lot of Dell, HP, Acer and Asus fans but you'll be able to search for your exact laptop model. It helps if you have your laptop's fan for reference, and check with the seller if the photos are of the actual item if you're not sure.My laptop turns off without any reason posted in: Notebook Shuts Down | After I turn on my laptop it works fine for 25-30 minutes and after that just turns itself off without any warning.

When I turn it on again, it works for some time and then shuts down again. What is going on? How can I fix it? Most likely you experience a laptop overheating problem and it would be fixed by cleaning the cooling module – the heat sink and the fan. The notebook processor produces a lot of heat when the notebook is turned on. The cooling module helps to keep the CPU cool when the laptop is working. The cooling module includes two parts: the heat sink and the cooling fan. The heat sink is attached to the CPU and helps to conduct the heat from the processor to the radiator. The cooling fan blows on the radiator and helps to disperse the heat produced by the CPU. The laptop will overheat if the heat sink radiator is clogged with lint and dust or if the cooling fan stopped spinning. If your laptop shuts down after some time without any reason and warning, check if the cooling fan spins. Usually it makes some noise and you can hear it. If the fan works fine, then check if the heatsink is clogged.

In some cases you can clean the heat sink with compressed air, just blow inside the fan openings on the laptop bottom. If the heatsink is completely clogged, then it is necessary to remove the heatsink for cleaning. This is my NextChorme tends to use a massive amount of ram and alot of CPU power. This then causes the heat output of the CPU to increase hence the fan speed increase. My PC is running with 32GB of ram and with about 20ish tabs, one of which is YouTube, the rest being forums and such, using roughly 8–14GB maybe 4 on a good day.It could have something to do with multiple windows open inside Chrome, such as Netflix, youtube and flash game that use alot of ram and CPU. It may help to only use one window at a time to make your fan quieter.Chrome is a very stable and fast browser and as a result it is very resource intensive. It is not uncommon to hear fan noise when using chromeA 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. 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. 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. 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.
