Legion 5 2021 fan noise

2021-07-19, 18:04 PM

Hello guys !

 

So a few days ago i bought the Lenovo legion 5 ( 15ACH6H ) and so far i love everything about this laptop except a noise that is coming from the fans. The noise is mainly audible when i use the laptop doing light tasks like web browsing for example. When the rpms of the fans rise, the noise becomes more high picthed. When i play games it doesn't bother me because i wear headphones. It's especially annoying when im studying for university, and its not coil whine or something. Do you guys know if this is normal or shall i contact Lenovo?

 

Here is a video from the noise: https://streamable.com/7ggyeg

 

Thank you guys!

Hello @Nickeva,

 

Welcome to the Community Forums.

 

I would suggest trying to perform a BIOS update on the machine if you haven't already tried that.

Some users have noted slightly reduced fan noise after the updates.

 

You can download it using this link (please note that you may have to enter your serial number in order to get the right file): https://pcsupport.lenovo.com/uk/en/products/laptops-and-netbooks/legion-series/legion-5-15ach6h/downloads/driver-list/component?name=BIOS%2FUEFI


Hope this helps.
Regards,
Jack_Lenovo1

Hello @Jack_Lenovo1   I've done all the updates on the drivers the day i bought it, so like 3 days ago, and i saw no difference. I appreciate your advice though!

Hello @Nickeva,

 

Thanks for writing back.

 

Have you tried pressing FN+Q to change the performance modes?

This should lessen fan activity.

Hello @Jack_Lenovo1 !!

 

I've tried changing the performance modes but nothing changed. The noise that is coming through the fans, as it can be heard on the video above, is weird... it's almost like a beat and that's why it's annoying...it sounds as if two waves with similar but different frequencies interfere with each other and produce an annoying beat. Do you think this is normal?  Sorry for the extended analyzing of the subject haha!

 

Thanks again for your advice!!
