There is nothing better than a laptop when it comes to working in your environment of choice, but portability comes at a cost: heat build-up is often a recurring problem due to the limited space that hardware components have inside for “breathe”, and this makes the notebook work with a noise level that often becomes annoying. In this article we are going to tell you what you can do about it in order to silence a laptop that makes too much noise.
Wondering why your laptop fan is so loud? Laptops, like 2-in-1s and other devices, have fans for one reason: to expel the heat generated by their internal components by circulating air. Most of the time when 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 generating too much noise, so let’s see what you can do about it.
Why is the laptop making so much noise?
Let’s start by looking at the reasons why your laptop’s fans can make more noise than necessary; We understand that the noise they make is not natural, that is, we all know that when we are putting a lot of load on the equipment the fans will work faster and emit more noise for it, but what we are referring to here is TOO MUCH noise , or a Noise that is not the natural one that should be heard when the fans are spinning fast.
The first reason why the laptop can make too much noise is obviously overheating . If the components are experiencing a high temperature, the fans will try to dissipate the heat by running faster. An abnormal overheating can occur for various reasons, such as that the ambient temperature is very high or that we are demanding a lot from the equipment and it is operating at the best of its possibilities.
Of course, the notebook can also make too much noise if its fan or fans are dirty . After all, there is no pure air, no matter how much we weigh, it always carries particles and these are gradually deposited both on the fan blades and in their surrounding environment, and can very easily cause the fan to make more noise. from account. You’d be surprised how much crap a laptop fan can accumulate in just one year of use.
Similarly, a laptop can overheat more than necessary and make abnormal noises if we have covered the vents , generally located both on the sides and at the back and at the bottom of the equipment. This problem is quite frequent, especially in people who use the laptop by placing it on their lap, since they literally cover the lower vents and do not let the air circulate inside.
Obviously, there is also the possibility that the fan is damaged and therefore makes abnormal noises. This happens frequently in laptops since 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 with some ease, especially if they are forced to “push “large amounts of dirt (as in the example image above).
How to silence a too loud laptop
Let’s start with the basics: Are you forcing your laptop to work to the best of its ability? If so, from now on we tell you that it is normal for the fans to be at maximum and that therefore the equipment emits a lot of noise; what would not be normal is that the fans run too fast and emitting a lot of noise when you are not doing anything, simply being at the desk with the computer asleep.
We therefore recommend that you start by reviewing the active processes you have by accessing the Windows Task Manager (right click on the Start bar -> Task Manager) and checking if there are processes that should not be there, or if there are any processes or service that is putting the laptop’s CPU at 100%. If so, try to “kill” the process (select it and hit the End task button), uninstall the application or, if you do not recognize the process at all, we recommend that you scan the computer for viruses or malware since that is precisely one of its modus operandi (for example, there is malware that installs itself on your computer and turns your CPU to 100% because they start mining cryptocurrencies).
If the laptop still runs on the fan too fast for no apparent reason, even if the CPU usage level is low, it is quite likely that the heatsink is not doing its job well and it is time to open the laptop and replace it. the thermal paste, taking advantage of course to clean the fan and the heatsink well. This is a process that differs for each laptop and that, if the laptop is still under the warranty period, we recommend that you do nothing but manage it with the manufacturer.
In any case, changing the thermal paste and doing a good internal cleaning of the equipment will undoubtedly help it to work at a better temperature and that the fan makes less noise, and it is in fact a task that every laptop user should carry out at least. once every one or two years.
If after all this the laptop continues to make too much noise, we recommend you install a hardware monitoring tool such as OpenHardwareMonitor or Aida64 and see if the temperature of the processor is correct, since there is also the possibility that the probe has been damaged temperature and is registering too high temperatures that are not real.
If the monitoring software shows normal temperatures, you can try a software solution to manually control the operating speed of the fans. In some laptops you can do it directly with OpenHardwareMonitor, but for others you will need to look for more specific applications like Speedfan. Some modern laptops also allow you to configure the fan speed or profile from the BIOS.
