Pavilion 15-CW1017nb - high pitched fan noise

[JVD95]

Hi everyone,

The fan on my laptop is producing an annoying high pitched whine. The noise was there from the first day. I wasn't really bothered because I didn't use the laptop much and if I used it, I put on some music most of the time. After a few long sessions without music, I realised the noise is unacceptable. I don't mind an audible fan, it's just the frequency that is very annoying to me. Even at the lowest speed.

I already change the bios setting to allow the fan to be turned off when temps are low enough. I also put cooling management to "passive". Lastly I set the maximum cpu speed at 50%, which lowers the performance but also decreases the cpu temperature and fan speed.

At idle the fan sometimes shuts off. This seems to happen when the temperature drops below 40 degrees. But even at the lowest speed the sound is doing my head in.

So here I am looking for a solution. I see many similar topics without a real solution.

I can think of 2 possible solutions, but HP's help might be needed:

1. Fitting a different fan, a replacement fan by HP or an aftermarket one.

2. Fan control software: at the moment the fan is off until around 40 degrees. The cooling could remain passive until 60° for example. At that point the fan could kick in pretty hard to allow a long passive period again.

In the meantime I'll play music or put on some headphones.

Thanks for any help!

Kind regards.
Joachim

Hi@JVD95, Welcome to the HP Support Community!

As I understand fan making a loud noise notebook.

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

Did you know that the fan is system-managed and cannot be changed manually?

Does the computer shut down due to overheating?

Have you recently made any changes to the computer before the issue started?

Have you tried to update the drivers and the Bios?

If you didn't, I'm afraid that's how the HP device is designed, making changes to fan speed may cause overclocking or over-throttling causing hardware malfunctions within the device and hence is not recommended or supported by HP.

If your device is overheating, please remember the below information:

NOTE: Generally, when temperatures inside the case rise above 35 degrees Celsius (95 degrees Fahrenheit), the risk of damaging important internal components increases greatly.

Also, to avoid CPU damage, we do not recommend throttling or overclocking the CPU, I recommend you refrain from using high-performance games on this laptop as it's not built for the same.

I would suggest you refer to the support documents as this will help you in resolving the issue.

Let's start off by updating the Bios, Chipset, and graphics card drivers on your PC from our HP support website, using this link.

Also, download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.
