HPEnvy x360 fan surge issue

[sPaul12]

Hi there,
Warranty for this HP ENVY x360 ended in 2019, and
everything was working alright until few days ago,
its cooling fan suddenly stopping for a second and
then surging to full power for about a second. This is repeating 
regardless of the laptop's temperature, even at cold start.

I have updated BIOS, it didn't resolve the issue.

Is there a way to figure out if this is a fan issue so that it can be replaced.

@sPaul12 Here's all you need to know and do, to resolve the issue:

• Updating your Notebook computer BIOS
• Keeping notebook air vents clear and clean
• Increasing the efficiency of the notebook to reduce heat
• Using Windows Task Manager to identify corrupt processes
• Selecting power save settings to shut off your computer when it is not in use

Thank you @Riddle_Decipher for the response.

I tried out the suggestions given by you. Seems like the fan is bad, I'll attempt to replace to see if that resolves the issue.

Today, when the computer was restarted I got the message that the cooling fan is not operating correctly.

Error - System fan (90B)

Thanks again
