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.

Then in the Security section, click the Protect against viruses and threats link.

alt=Protection against viruses and threats data-ezsrc= />Open protection against viruses and threats

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.

Step Five: Select Power Save [On] from the drop-down menu in the Power Options dialog box.

Step six: In the following box, expand the Sleep After option and reduce the duration of the Sleep After and Sleep After options. Decrease the value from the originally set value.

Click Apply and OK.

Now restart the computer and check if you get rid of the annoying computer fan noise.

6. Clean dust when computer fan is noisy

If there is dust on the fan or internal computer equipment, the heat output will be higher. Dust on the CPU and motherboard causes many other serious problems besides fan noise.

You can use a vacuum cleaner or compressed air blower to remove dust without damaging the computer hardware. Be sure to clean the unit and fan carefully, as minor damage can cause unwanted problems.

Also clean the computer’s vents; if they are clogged with dust and dirt, you may have problems with airflow, which can cause the temperature to rise. Check if something is hitting the fan blades and causing the noise. If you have not opened your laptop or desktop computer yourself, we recommend that you let a professional do it.

7. Update graphics driver

Outdated video card drivers can cause problems with noisy computer fans. In this case, you can either update the drivers manually or use third-party software to do so.

To manually update the graphics driver, open Device Manager by looking for it on the Start menu and unzip Display Adapter.

Right-click on the graphics driver and select Update Driver from the context menu.

Follow the on-screen instructions to complete the update process. Restart the computer after updating the driver and check whether the computer’s fan is noisy or not.

8. BIOS Update

Many Windows users have fixed their computer’s fan noise with a BIOS update. You can also refer to the BIOS update manual to learn how to do this correctly.

If you have never done this before, we recommend that you seek the assistance of a technician. Make sure the update is performed correctly, as an incorrect update may cause irreparable damage to the computer.

9. Making BIOS changesFan control settings

You can open the BIOS and change the fan control settings to fix the computer’s fan. BIOS settings for fan control vary by model and manufacturer. Therefore, to know how to access the BIOS and make the appropriate changes to the fan, you should consult the PC’s user manual or the manufacturer’s website.

You can adjust the fan speed in the BIOS to match the processor temperature, but the BIOS is not required to do so. If there are no fan control settings in the BIOS, check with the manufacturer to see if there are third-party alternatives supported by your PC for fan control.

Some Windows users choose SpeedFan to control fan speed and work with other controls. You can download and install SpeedFan on your computer.

10. Replace computer fan

If your computer’s fan is still noisy even after trying all the above solutions, it’s time to replace it with a new one. You may experience noise problems if the fan is too small for your system, or if there are malfunctions in the hardware components. You can search based on CPU, GPU and your PC to find the perfect fan.

If you are unsure of your system configuration, you can contact the manufacturer’s support department to help you choose the fan.


A computer fan is an important part of your PC’s hardware that keeps the internal temperature under control by blowing warm air. And that’s why it’s important to check them out. If it makes too much noise, there may be a problem with your computer that you need to check. The above solutions explain what you can do if your computer’s fan is noisy and causing unwanted interference.

If the problem is not that serious, you can easily fix it by terminating certain tasks in the task manager. However, if the fan hardware part is damaged, you may need to replace it with a new part.
