HP All-in-One PCs - Fan is noisy and spins constantly (Windows 11, Windows 10)

When a computer fan spins loudly for a long period of time, there might be an issue with the fan, or the computer might be overheating. You can use the following solutions to try to resolve the issue.

Note:

It is normal for the fans to spin loudly for five to twenty seconds when you turn on the computer.

Adjust the computer power settings

Adjust the power settings to decrease power consumption, which can help the fans maintain an optimal internal temperature up to 30°C (86°F).

Adjust the computer power settings (Windows 11)

Use this procedure to adjust the power settings for a computer running Windows 11.

Turn on the computer.
Click the battery icon on the right side of the taskbar, and then click the Settings icon.
On the System screen, click Power & battery.
Select Best power efficiency from the Power mode drop-down list.

If the issue persists, continue to the next step.

Adjust the computer power settings (Windows 10)

Use this procedure to adjust the power settings for a computer running Windows 10.

Turn on the computer.
In Windows, search for and open Control Panel.
In the Control Panel search field, type power options, and then click Power Options in the list.
Click Change plan settings.
Click Change advanced power settings.
Click the drop-down menu, and then select Power saver.
Select Sleep from the list, and then click Sleep after and Hibernate after to open each setting.

Note:
Sleep mode places the computer in a power-saving mode that does not close any open applications. Hibernation mode saves any work in open applications, and then turns the computer off.
Decrease the amount of time for each setting to reduce unnecessary strain on the fans when the computer is not being used.
Click OK to save the changes.
Restart the computer.

If the issue persists, continue to the next step.

Clean the air vents

Dust and debris can accumulate in and around the air vents over time, obstructing the airflow and causing the fans to work harder than normal to cool the computer.

Turn off the computer.
Remove any objects near the computer.
Use a vacuum to clean the vents at the back and sides of the computer.

Note:
The following image is an example of where your computer vents might be located.
Turn the computer on.

If the issue persists, continue to the next step.

Increase efficiency to reduce heat

The computer works harder and generates more heat when multiple applications are open simultaneously, or while playing graphically intense video games.

Use the following tips to improve computer efficiency.

Change which applications run when Windows starts by using the Startup tab in Task Manager.
Close applications when you are done using them.
Close the internet browser when you are not using it.
Lower the game resolution and decrease the graphics settings if the computer becomes warmer than usual while playing.

If the issue persists, continue to the next step.

Using Task Manager to identify corrupt processes and reduce heat

When multiple processes, such as corrupt software or malware, overburden the CPU, the fans run continuously to remove the excess heat. Open Windows Task Manager to identify these processes, and then close them.

Note:

An unnecessary or corrupt process can consume anywhere between 1% to 100% of the CPU. Even a low but constant 3% to 4% load can cause the fans to spin faster.

Make sure that your computer is connected to the internet.
Press ctrl + alt + delete, and then select Start Task Manager or Task Manager.
Click More details, if necessary.
Click the Processes tab, and then click the CPU column header to sort the processes by CPU load.
Use the internet to research and confirm any suspicious processes that are displayed in the list.
Select each suspicious process, and then click End task.

If you did not find any suspicious processes or the issue persists, continue to the next step.

Update the graphics driver

The graphics driver might be out-of-date. Use Windows Update to find and install updates for your computer.

Note:

HP does not recommend installing drivers from third-party websites, because those drivers can create additional problems. If you choose to install a third-party driver, make sure that you create a Windows System Restore point before starting the update. Go to HP PCs - Using Microsoft System Restore.

How To Update Windows 10

Learn how to update Windows 10.

Make sure that the computer is connected to an active internet connection.

Note:
On a metered internet connection, such as a cellular network, you might need to download updates manually.
In Windows, search for and open Windows Update settings.
Click Check for updates. Any available updates install automatically.
After the updates install, restart your computer, if necessary. For more information, see HP PCs - Updating drivers using Windows update (Windows 11, 10).

If the issue persists, continue to the next step.

Update the BIOS

The computer BIOS might be out-of-date. Check for a BIOS update from HP.

CAUTION:

Make sure that you install the BIOS update for your specific computer model. Installing the wrong update can result in losing all computer functionality.

Go to HP Customer Support - Software and Driver Downloads, and then navigate to the product page for your computer.
Fine BIOS in the list.
- If the option is not available, the BIOS is up-to-date.
- If the option is available, click BIOS, and then click Download next to the update. Follow the on-screen prompts, and then restart the computer. For more information, go to HP Business Desktop PCs - Updating the BIOS (Basic Input Output System) or HP Consumer Desktop PCs - Updating the BIOS (Basic Input Output System) (Windows).

If updating the BIOS did not resolve the audio issue, continue to the next step.
