Suspicios CPU noise

[Mtrainer]

I bought in January 2021 an HP laptop, with Intel i5 1135g7 processor, 11th generation, 16 GB RAM, 512 GB SSD. For about a month I noticed by chance that I hear an electric sound, a kind of continuous humming and with different intensities in the CPU processor area. Is that noise normal?

The CPU does not make noise.   But, a poorly designed motherboard/device does.   Contact HP for support.

I have already contacted HP and they told me to send the laptop to the service for verification. After I received it from the service, I was informed that they changed the motherboard. When I turned on the laptop I found that the noise was still present and not receiving the motherboard changed as proof of replacement, I decided to send it back to service. And after the second check the motherboard was again changed (I saved the Serial Number for the latest motherboard) and the noise, just like the first time, was present. For these reasons, I decided to post my problem on the Intel forum and receive expert advice. The motherboard is Intel, model 87.FE and the laptop is HP 15S-FQ2012NQ. Please help me!

Sorry, HP is responsible for all support and warranty of your laptop.  Work this out with HP.

I will obviously continue to address HP. I would have liked to know other opinions of expert users. So, it could be a manufacturing or design problem, but since 3 motherboards were practically successively mounted on the laptop and the noise was always present?

Hi @Mtrainer 

If the noise you are hearing in the CPU area, it can be generated by the Cooling Blower. You may download and run free HWiNFO64 application.  Check in the Sensors section the Cooling Blower RPM change with the CPU temperature change. Check if the noise change corelates to the blower RPM. If you find that this is a blower, making noise, ask to replace it. But you should know that in high RPM, it is normal to hear the blower.

Sorry but the noise is not related to the cooler fan functioning. It can be heared from the moment laptop is power on.

The Cooling Blower is working from the moment the laptop is powered ON.

Hello Mtrainer, 

Thank you for posting on the Intel® communities.

I would like to let you know that, as the community mentioned, this could be related to the CPU fan, and in the rare case that is the processor itself that is making the noise the best action to take would be to replace the unit.

Since you have a laptop, you are not able to replace only the processor or the socket (even if it were a motherboard), I recommend you to get in contact with the laptop manufacturer and check for possible troubleshooting steps or warranty options.
