Ideapad S340 starts making way more fan noise after a BIOS update

2020-08-02, 19:52 PM

Roughly two weeks ago I bought a Lenovo Ideapad S340. The laptop worked really well and I was happy with it. 5 days ago I got a notification about an urgent BIOS update. After this update my laptop fans started making a lot of noise and revving at unnecessarily high speeds. I've noticed that this happens when core temperature exceeds 60 degrees celsius. Before the update it would starting making the same amount of noise at 80 degrees which is way more acceptable. The BIOS update whent without any issues so I'm not really sure why it started doing this. Is there any way to resolve this issue easily? 

I would prefer to not reset my software or to do a bios back flash but I would like this issue to be resolved. 

 

Any advice is appreciated!

it also seems to be that with the latest bios (28) fan speeds and cpu frequencies are different and weird.

it is also bad that no advanced options for fan/temps are present in bios.
