Laptop fans running fast despite low temperature

Pavilion BC450
Microsoft Windows 10 (64-bit)

Hello,

 

Around a month ago I bought a HP Pavilion BC450 laptop and since I've got it I've had an issue with the laptop's fan.

The laptop's fans run too fast and are quite noisy despite not doing any heavy work.. For example, I've been studying and simply viewing some PDFs and the fans would run at 3000 RPM, which is incredibly noisy. I've also been tracking the temperature and the CPU/GPU is at around 40ºC, which is low and shouldn't make the fans run so fast.

 

I've tried updating windows to the last version, updating the BIOS and other drivers and nothing seems to work. I've also tried using HP coolsense and it doesn't make much of a difference, the fans still run faster and louder than they should.

 

Is there any way I can control the fans or should I just give up and send it to the warranty?

 

Thank you.

@FunkyExpert
Thank you for posting on the HP Support Community.

 

The most common cause of overheating is the accumulation of dust inside the laptop. ... The sound of the fan running constantly may indicate that the laptop is getting hot and is not running as efficiently as possible and that there is a problem with accumulated dust clogging the air vents.

Let's try this workaround:

Boot the computer into the Bios and change adapter settings:

1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your notebook, as it is starting press the  F10 button repeatedly

4. Use the arrow keys to scroll through the BIOS list until you highlight "Advanced." Press "Enter."

5. Use the arrow keys to scroll down to "System Configuration," then press "Enter." Use the arrow keys to navigate to "Device Configurations," then press "Enter."

6. Use the arrow keys to navigate to "Fan Always on when A/C Power," then press "Enter" to enable it. Press the "F10" key to save the setting and exit the system BIOS. For more information see Reducing Heat Inside the PC
