Noisy fan in a laptop

Noisy laptop performance is a fairly common problem that users face. The sound coming from the body, leads to discomfort, annoying. Especially often this happens in the summer, when high temperatures make the internal cooling system of the device work to the limit. But even in this case, the problem with the hum can be eliminated if you find out its cause.

Why is the laptop noisy?

Too loud operation of the device is a problem that results from a number of malfunctions. Most likely, the reason is as follows:

• Incorrect software settings;
• Intensive work of any programs;
• A large accumulation of dust inside the laptop;
• Overheat;
• Malfunction of components.

Important! You can immediately contact the specialists in the service center. But the problem is most likely not so complicated. Therefore, you can try to calculate and fix it yourself.

One of the reasons for the internal buzz may be processor congestion. To check why the cooler was noisy, you need to open the Task Manager program on the computer. To do this, press the key combination "Alt", "Ctrl" and "Delete". After that, a tab will open, at the bottom of which you can see the percentage of processor utilization. If the figure is close to 100%, then you need to find out which program is the reason.

Having found the application loading the processor in the list, you need to hover over it and click once with the right mouse button. An additional menu should appear, in which you should select the line “Open file storage location”. In it you can see the files executing the program process, wasting the resource of the device.

If it turns out that these files are stored in a folder called "Temp", then you can safely terminate the application. This action will help the system to unload and literally slow down. It is especially important to complete this process, if among the documents found there are those whose name cannot be read, consisting of a set of random characters.

For all program changes to take effect, you must necessarily restart the laptop. If the problem is resolved, the device will become much quieter.

Important! Sometimes computer systems are affected by virus programs that run malicious applications that require huge resources.

Because of them, the processor can overheat, so the coolers start spinning at the highest possible speed. A characteristic rumble appears. That's why on every device you need to have a powerful antivirus with updated databases and make system images.

What to do when the cooler is buzzing?

One of the factors causing annoying noise can be fan contamination, which provokes their loud performance. Over time, dust accumulates inside the device, settles on the cooler blades, prevents normal air circulation and thereby causes overheating. This not only interferes with the adequate operation of the device, but is also a great threat to the central processor, one of the most important parts of any computer.

When the laptop is very hot, the temperature sensor responds, causing the cooler to work intensively. Then a characteristic noise appears. Urgently need to clean the device, removing dust both inside and out.

Attention! Experienced users are advised to resort to self-cleaning only after the warranty period. Opening and disassembling the device will invalidate the manufacturer’s warranty.

The cleaning process is important to carry out on a turned off laptop. You must make sure that the computer is not put to sleep.

First you need to very carefully detach all the parts of the device without exposing them to additional pressure. Remove dirt with a dry cloth, cotton pads and sticks. And from hard-to-reach places dust can be blown out using a can of compressed air. You can buy one at any hardware store.

The cleaning procedure takes time, since increased attention and scrupulousness are required. After its completion, you need to close the lid, carefully tighten all the screws and then start the laptop to check the result. The device will become much quieter and will warm up less in the process if the cause was dust accumulated inside.

But, most likely, after a while the help of an experienced specialist will be needed, who will carry out a “general cleaning”, removing all contaminants and replacing thermal grease.

Loud laptop noise during long work

The fan may be very humming due to incorrect settings in the BIOS, the basic input system. You can fix them yourself as follows.

First you need to restart the laptop to enter the BIOS. But there is one caveat: the method of entry varies depending on the brand, model and year of manufacture of the device. But usually when loading you need to press the “Del” button or, if nothing happened, you can try the “F2” key.

The dialog box should look something like this: “Press F1 to continue, DEL to enter setup”, “Press DEL to run setup” or “Please press DEL or F2 to enter UEFI BIOS settings”.

Using the arrows, go to the line “Hardware Monitor”. It is very important to pay attention to the parameter "Q-Fan Function". If “Disabled” is written across from it, then it is disabled. This needs to be fixed by changing the status to “Enabled”.

Then go to the line “CPU Target Temperature”. This item is responsible for setting the temperature. It is likely that the parameter with the wrong value is set there, which is the reason for the cooler hum.

You need to click on this indicator, thereby opening a window to select the desired temperature, and set the value to 50 degrees. This simple setup is able to get rid of problems with the drone, after which the laptop will work much quieter.

Will the repair help?

Often there are times when inside the working laptop you hear not the hum of the fan at all, but some kind of strange tapping, clicking. Sometimes even a sound appears, like a rattle, as if parts of the cooler cling to each other. In this case, the situation is really serious. To solve it, you need to buy and install a new fan. Doing it yourself is not recommended.

Also, the cause of the hum can be a dried thermal paste. This is a special substance designed for heat wire, sealing and connecting parts of the device. On the network you can find a huge number of articles and videos on how to replace thermal grease yourself. But it is better to turn to professionals immediately with this problem. Sometimes a laptop is very difficult to disassemble and properly assemble back. In addition, with the intervention of an inexperienced user, there is a risk of damage to parts. And this promises additional costly repairs.

Any equipment, including a laptop, requires compliance with the rules of operation and appropriate care, which, unfortunately, many users forget. Any problem is easier to prevent than to solve. To minimize problems with the laptop, you should regularly wipe it from dust.

Important! During operation, do not place it on a bed, blanket or other surface that blocks the access of air to the fan. Also, do not use a laptop on hot days and even more so leave it in direct sunlight.

Another solution to the problem of overheating of the device may be to use a special stand. Such devices are specifically designed to cool the laptop. One or more additional fans are installed on them, blowing the computer case and thereby lowering its temperature. The quality and cooling power greatly depends on the manufacturer, model and cost of the gadget.

A stand with an integrated cooler can really help to cope with the increased temperature of the device. But nothing protects the laptop from dust accumulation. Dirt settles not only on the fan parts, but also clogs the microcircuit, disrupting the flow of necessary air and preventing heat dissipation. A large amount of dust can even lead to burnout of contacts, malfunction of the motherboard, video card or processor. All this will entail component replacement and costly repairs. Therefore, experts recommend doing an internal cleaning of the laptop once every six months, without waiting for the appearance of noise or other unpleasant “symptoms”.
