Wondering why your laptop fan is so loud? Laptops, like 2-in-1s and other devices, have fans for a reason: to expel heat generated by their internal components by circulating air. Most of the time when the fans turn on it’s because they have to, but there are times when they seem to be running too fast for no reason and making too much noise, so let’s see what you can do. on this subject.
Why is the laptop making so much noise?
Let’s start by looking at the reasons why your laptop fans may make more noise than they need to be; We understand that the noise they make is unnatural i.e. we all know that when we put a lot of load on the equipment the fans will run faster and make more noise, but what we are referring to here is Too much noise, or to a noise that is not the natural noise that should be heard when the fans are running quickly.
The number one reason why the laptop can make too much noise is obviously because overheated. If the components are experiencing a high temperature, the fans will try to dissipate the heat by running faster. Abnormal overheating can occur for various reasons, such as the ambient temperature is very high or the fact that we put a lot of demand on the equipment and that it performs to the best of its ability.
Of course, the laptop can also make too much noise if its fan (s) they are dirtys. After all, there is no clean air, no matter what our weight, it always carries particles and these gradually settle both on the fan blades and in their surrounding environment, and can very easily make the fan make more noise. . You’d be surprised at how much crap a laptop fan can accumulate in just a year of use.
Likewise, a laptop can overheat more than necessary and make abnormal noises if we have the vents, usually located both on the sides and at the rear and bottom of the equipment. This problem is quite common, especially among people who use the laptop by placing it on their knees, as they literally cover the bottom vents and do not let air circulate inside.
Obviously, there is also the possibility that the the fan is damaged and that is why it makes abnormal noises. This happens frequently on laptops because their fans are always blower type and thin enough to fit into the case, so the blades are small and thin and tend to break quite easily, especially if they are forced out of the case. “ push ” Large amounts of dirt (as in the example image above).
How to silence a loud laptop
Let’s start with the basics: do you force your laptop to work hard
We therefore recommend that you start by reviewing the active processes that you have by going to Windows Task Manager (right click on the start bar -> Task Manager) and checking if there are any processes that do not. should not be there, or if there is any process or service that puts the laptop’s processor at 100%. If this is the case, try to ‘kill’ the process (select it and press the End task button), uninstall the application or, if you do not recognize the process at all, we recommend that you analyze the process. ‘computer looking for viruses or malware, as this is precisely one of its modes of operation (for example, there is malware that installs itself on your computer and turns your CPU to 100% as it starts to to mine cryptocurrencies).
If the laptop is still running too fast on the fan for no apparent reason, even though the CPU usage level is low, then there is a good chance that the heatsink is not doing its job well and it is time to open it up. laptop and replace it. thermal paste, taking advantage of course to clean the fan and the radiator. This is a process that is different for each laptop, and if the laptop is still under warranty, we recommend that you only handle it with the manufacturer.
Either way, changing the thermal paste and doing a good internal cleaning of the equipment will undoubtedly help it to run at a better temperature and the fan to make less noise, and it is actually a task. that every laptop user should perform at least once every one or two years.
If after all this the laptop continues to make too much noise, we recommend that you install a hardware monitoring tool such as OpenHardwareMonitor or Aida64 and see if the processor temperature is correct, as there is also the possibility that the probe has been damaged. and records excessively high temperatures which are not real.
If the monitoring software displays normal temperatures, you can try a software solution to manually control the running speed of the fans. On some laptops you can do this directly with OpenHardwareMonitor, but for others you will have to look for more specific apps like Speedfan. Some modern laptops also allow you to configure the fan speed or profile from the BIOS.
