The laptop cooling protects the computer from overheating. Users should listen even more closely if the notebook suddenly makes strange noises. A loud rattling or hissing often indicates serious problems.
Loud laptop ventilation is the equivalent of sweating in humans: it means that the computer has to work very hard right now to deliver the required performance and handle all the tasks. To protect the hardware from overheating, more fresh air is needed and the built-in mini fan runs faster. Sometimes it can get very loud.
There is not always cause for concern. But if the ventilation starts up or rattles loudly for no reason, it’s worth a look under the hood. Here are the causes and solutions for loud laptop ventilation.
That’s why ventilation is so important
Because all components in the notebook are close together, the heat builds up in the housing much faster than in a desktop PC. Proper ventilation is all the more important. It protects the hardware from permanent damage and prevents the system from crashing due to overheating.
Users must ensure that the heat can escape easily. For example, it is not a good idea to place the notebook on a cushion that blocks the ventilation slots for long periods of time. Over time, dust and dirt can also build up in the components and impede air circulation.
Clean parts and keep them in good condition
Especially with older notebooks, it pays to unscrew the case and carefully remove dust from the inside. This works best with compressed air. You can find the accessories in computer or photo stores.
Over time, there may also be signs of use. The fan is in fact a mini fan, i.e. a mechanical part that wears out. If the ball bearing is no longer stuck or parts come loose, it will cause a loud rattling. But that can be easily remedied – with a spare part, for example.
If the problem is deeper
It becomes more difficult when the cause cannot be identified at first glance. Problems at the software or operating system level can also put excessive strain on the processor – and with that, the ventilation clocks.
This is immediately noticeable when playing with high-resolution graphics or working with computer-intensive software: the computer runs at full speed, becomes audibly louder or even warms up. That alone is not a cause for concern – most notebooks have mechanisms that sound the alarm in time or save resources in an emergency.
But when the loud ventilation becomes a permanent phenomenon and the computer starts panting from simple tasks or for no apparent reason, you need to take a closer look. An unwanted program may be running in the background.
Tip: with Windows Task Manager you can usually find out about the performance pigs quickly. In addition, a virus scan is worthwhile to detect hidden malware, and a Quick check using Windows performance monitoring.
This makes the fan quieter again
Users can also indirectly control the fan through the notebook’s settings and prevent it from becoming loud. Some models have a so-called “silent mode”. This prevents the fan from running at full speed. At the same time, however, system performance is also limited. Silent mode can usually be turned on and off with a special key on the laptop’s keyboard.
The energy-saving mode in the Windows settings has a similar effect. These can be found in the control panel in the “Energy options” submenu. You have to accept that the computer may run slightly slower. In return, the hardware is spared – and the environment, too.
Experienced users can also control the fan speed at the BIOS level. However, this also limits the cooling capacity and increases the risk of overheating. You should be able to estimate how much you can expect from your own computer.
These tips keep the notebook cool
Notebooks with an SSD hard drive have a clear advantage here: This type of hard drive develops less heat during use, so that the devices usually run more quietly than devices with an HDD.
Regardless of equipment, the following applies: If your notebook gets noticeably loud or hot, take a short break. Shutting down all programs, shutting down the computer and waiting a while before restarting can work wonders.
While at work, it is best to close all programs that you are not actively using. This saves power and protects the battery or reduces power consumption. The Google Chrome browser, for example, has a reputation for having a lot of energy. A few more or less open tabs can make a difference here. That too The Autostart menu must be cleared from time to timeso as not to unnecessarily burden the CPU. More about this here.
There is only one thing you should absolutely not do: try to bring the notebook back up to temperature from the outside, for example using ice packs or ice packs. If it cools down too quickly, fine droplets of condensation water can form inside and the hardware can shut down permanently.
