One ventilator doesnt work

[Cheethell]

Hello,

My laptop has a problem with one fan (ventilator).

There sometimes occurs an error message, that cooler, fan is not working properly. So I decided to check it. I opened my laptop, cleaned it and started. I saw that one fan is not working. So I disconnected both and changed them. Then the other one, which used to work, didnt work. It means that both of fans are working, but the problem is somewhere else.

Could you please tell me what could be broken? And how it repair ? Thanks a lot.

Hi@Cheethell, Welcome to the HP Support Community!

As I understand fan is making noises,

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.

Refer to this link to know how to use HP support assistant.

Thanks for advices and response.

I am sorry that I didnt write the issue understandable. I dont have any problem with noise of fans.

I have a problem that when the laptop is working only one of two fans are working. Also during playing, when the computer needs second fan, the second one is still not working.

So I thought that the right one is broken, so I changed them. I put right fan to the left plug and left fan to the right plug. But the fan from the left which previously was working, also didnt working in the right plug.

I updated the BIOS as you recommended me, but the problem is still here.

I did some stuff in HP support assist. But every test was passed without problem.

I didnt make any changes to the computer before.

I didnt changed the speed of the fan.

 I downloaded program only to check speed of fan

Actually the program is showing that second fan has speed of 217 RPM, but in reality it isnt moving, so it has 0 RPM.

Maybe the plug on the motherboard where is fan connected is broken. Dont you think? Or do you think it could be software issue?
