Lenovo 740 Cooling Fan noisy

2021-11-25, 9:32 AM

Hi

 

I have very loud noise coming from one of my fans on a Lenovo Y740 laptop.
I have cleaned the fans which have not made any noticeable different.
It is the fan on the lefthand side, when looking from the backside of the laptop.

 

Do you have any further steps you can recommend before considering to change the fan?

 

Best Regards

Thomas

Hello @Tompeds ,

 

Welcome to the Community.

 

There were some BIOS update on gaming machine that was listing about fan regulation fix.

 

If you can share your current BIOS and the machine type model / MTM from the sticker then we can check if you have the latest.

 

Update us back soon as convenient.

 

Regards,

Hello  @Tompeds  ,

 

Greetings.

 

When did the issue started?

 

Checking the current BIOS for the model shows Version BVCN16WW(V1.12) like yours.

 

I would still suggest going back to the BIOS page and reload the defaults then save and exit.

It can also help having the Vantage Gaming features added and see how it goes in different performance modes.
