Fan noise, casing problem?

2021-07-17, 16:16 PM
Hi, I have a whistling problem, when I put an A4 sheet of paper on the air inlets, it stops whistling. Is there any repair method that does not interfere with the equipment and allows the equipment to be repaired? Would they fix it under warranty?
He writes it because probably everyone has it. I have three options - return to the store, compensation from Lenovo for poorly constructed housing or repair of equipment.
I like this laptop very much, but the Boeing 747 will fly over me when whistle.
I'm not the only one and everyone has ten problems with Legion 5 15ACH6H from 2021.

Hello @reaxtic,

 

Welcome to the Community Forums.

 

Would it be possible for you to try and send us an audio sample of the issue?

It might be possible that this is because of coil whine.

Hope this helps.
Regards,
Jack_Lenovo1

Good morning,
it's not a coil whine, you have recordings on reddit. This is a whistle that is heard near the housing / air outlet. This is caused by the housing. When we block inlets or outlets, the whistle stops. If it were a coil, the sound would not fade after clogging the fans and even increase due to the fans spinning faster. I am waiting for Lenovo to admit the error and somehow remedy it. It remains to service the lower flap or air outlets. Here you go https://www.youtube.com/watch?v=F3PfuDASNxY
If u support specialist you should know that such a problem occurs in Legion 5 from 2021, after all, they write about it everywhere and the Russian forum is a whistle like this legion. This is a design flaw.
