Loud fan

[HappyTree_405]

I just bought an OmniBook 3 laptop, and the fan is SO loud.  I previously had an HP Pavilion laptop that wasn't nearly this loud.  This is going to drive me bonkers.  Is there any fix for this?  Please help before I throw this thing across the room.

If the fan on your HP OmniBook 3 is running loudly, it is often caused by high CPU usage, background processes, outdated BIOS, or thermal settings. Follow the steps below to troubleshoot the issue.

• Click More details if necessary.
• Select the Processes tab.
• Check the CPU column.
• If one application is using a high percentage of the CPU: Save your work.
• Close the application or end the task if it is not needed.
• Wait a few minutes to see if the fan slows down.

Step 3: Install Windows Updates

• Press Windows + I to open Settings.
• Go to Windows Update.
• Click Check for updates.
