Constant fan noise of Legion 5 15ACH6H

2021-07-04, 16:00 PM

Hi all,

I purchased this laptop a few days ago and after it's updated to BIOS ver GKCN36WW, the fan is turned on all the time even on idle.

When I tried to shift mode using Fn+Q, the fan still operated at the same speed and nothing changed. What's the point of Quiet mode then and how can I solve it?

Thanks.

Hello @Ke_n,

 

Welcome to the Community Forums.

 

Did the fans perform better on the previous BIOS version?

I would suggest trying to load BIOS default settings in the BIOS menu.

 

BIOS reset

- Press the power button to completely shut down the unit.

- Press the F1 repeatedly on startup to enter BIOS.

- Navigate to the "Restart" tab

- Press "Load Default Settings"

- Save & Exit changes or F10.

 

Some instructions on how to open the BIOS: https://support.lenovo.com/us/en/solutions/ht500216-recommended-way-to-enter-bios-ideapad


Hope this helps.
Regards,
Jack_Lenovo1

I think GKCN36WW is my first BIOS version. I have loaded default settings in BIOS but nothing changed. Is there a way to manually control fan speed? I know there're three fan modes in my device but they don't make any difference.
