The computer’s fans cool the computer when the internal heat flow increases. This usually happens when the load on the computer increases. However, if your computer’s fan makes so much noise over a long period of time that you can’t concentrate on your work and it bothers you constantly, something is wrong.

The hardware in the computers, such as. B. the processor, the graphics card and processors, the power supply and many other small parts generate heat. Processor or laptop fans are designed to cool the processor or laptop so that the performance of your system does not decrease.

This kind of computer fan operation is normal, but if it moves like a small plane, you need to do something to fix it. Fan noise is annoying, but it can also affect your computer’s internal hardware and performance.

What should I do if my computer’s fan is noisy?

Computer fan noise can be caused by high-end software on your computer or some kind of malware. The computer’s fan may also be noisy due to certain hardware problems. Once you find the solutions below, you will know what is causing the noise and how to fix it.

1. Monitoring of processes and running software

Your computer’s fan is making a lot of noise, probably because high-tech gaming processes or video editing software is running on your computer. Sometimes applications run in the background without us knowing, taxing processors and heating up computers.

You can check all these processes in Windows Task Manager. Press Ctrl + Shift + Esc to open Task Manager and click on the Details button if you don’t see any processes.

Go to the Processes tab and check all the processes going on there. Be sure to check all processes in the background to make sure there are no issues with the background software.

You should check the CPU usage for all processes; if it is close to 100%, this could be the reason why the computer’s fan is noisy.

If you find one of these processes, you can right-click on it and select End Task to temporarily stop it. Once the computer has cooled down and the fan is no longer making noise, you can open the shredding tasks/applications again.

If a running process continues to appear even after it is interrupted, it is likely that there is malware or a virus on your system. You can use the following solution to detect and remove malware on your computer.

2. Scan for malware and viruses

Malicious software can take up all of your computer’s resources, causing the computer’s fan to make a loud noise. You can scan your computer for viruses and malware with Windows Security. If you use third-party antivirus software, make sure it correctly removes malware.

Press the Windows + I key to launch the Settings application and go to Updates and security. In the left pane, click Windows Security.

Click on the Scan Options link to see the available scans. Now select the Scan Complete option and click on the Scan Now button to start scanning your computer for viruses.

Perform a full scan of the computer.

Restart the computer when the scan is complete and check that the fan noise has disappeared after the malware has been removed.

3. Allow the computer to cool down

If your computer’s fan is just making noise because your computer is generating a lot of heat, you need to let it cool down. Disconnect all external devices connected to the laptop or desktop computer. Also, unplug the power cord when using a notebook computer. Once everything is unplugged, turn off the computer and wait an hour.

Now check that the laptop or processor is at normal temperature and does not feel hot. After that, you can restart the computer and check if this will fix the noisy computer fan or not.

If the computer’s fan is only making noise because of heat, this will probably solve the problem.

4. Ventilate the PC.

The computer’s fan can be noisy if the laptop or processor is not adequately ventilated. Airflow is necessary to keep the material in the system cool. Do not place the laptop on a pillow, notebook or other soft surface. These surfaces generate heat and also prevent air circulation.

In addition, avoid covering the processor with any cloth that might impede ventilation and generate heat. To avoid the noise of PC fans, you can use laptop tablets and tables with fans to cool your PC in case of overheating. If you have adequate ventilation and the computer’s fan is making too much noise, something else is going on.

5. Change power supply settings

When the power consumption is lower, the temperature inside the PC may drop. The computer’s fan can maintain the temperature in such scenarios without making noise. You can change the power settings to eliminate the noise from the computer fan.

Step one: Open the Control Panel by searching in the Search section of the Start menu.

Step two: In Control Panel, search for Power Options and open it from the search results.
