Brand new laptop. CPU fan ramping up to 100% while idling

[MrLakeShow]

I just received my new laptop from HP. Upon finishing windows setup I noticed the CPU fan ramped up to 100% within about 5 minutes of boot-up and made slight, but noticeable high pitched whistling noise. I downloaded HWMonitor and noticed the CPU (Ryzen 7 7730u) is idling at around 42-45 degrees, and randomly spikes up to 79-80 degrees while idling, at which point the CPU fan will ramp up to 100% making the high pitched noise. These spikes will last for about 10 seconds and then settle.  Is it normal for the CPU fan to ramp up to 100% while web browsing/idling every few minutes? Doesn't seem normal to me, but I could be wrong.

Hi @MrLakeShow,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

If you have a brand new HP 17 Laptop PC and the CPU fan is ramping up to 100% while idling, there are a few potential reasons for this issue. Here are some troubleshooting steps you can try.

• Check for background processes: Open the Task Manager on your laptop (press Ctrl+Shift+Esc) and check if there are any processes or applications consuming excessive CPU resources. If you notice any, try closing or uninstalling them to see if it resolves the issue.
• Update your drivers: Outdated or incompatible drivers can sometimes cause high CPU usage and trigger the fan to run at maximum speed. Visit the official HP support website and download the latest drivers for your laptop model, particularly the chipset and graphics drivers. Install them and see if it helps to resolve the problem.
• Scan for malware: Malware or viruses running on your laptop can also cause high CPU usage. Run a thorough scan using reliable antivirus software to detect and remove any potential threats. Make sure your antivirus software is up to date before performing the scan.
• Check power settings: Incorrect power settings can sometimes lead to excessive CPU usage. Go to the Power Options in the Control Panel (or Settings) and ensure that the power plan is set to Balanced or Power Saver. High-performance power plans tend to use more CPU power, which can result in increased fan speed.
• BIOS update: It's possible that there may be a bug in the BIOS that is causing the fan to run at high speeds. Visit the HP support website and check if there are any available BIOS updates for your laptop model. Follow the instructions provided by HP to update your BIOS if necessary.

I hope this helps. 
 

Take care and have a good day.

The issue was resolved by switching the Processor Performance Boost Mode from Aggressive to Efficient in the Power plan advanced settings. The CPU runs much cooler and I haven't heard the fan ramp up to 100% after the change.
