G570 - noisy fan is always running

[smaaz]

@ rzfreefr

BIOS: 40CN23WW(V2.09) and i cannot monitor or control fan, tried speedfan and many other utilities,
but do check on your model as my fans cuts off at 41C and comes back at 56C .. this means there is no problem with the fan but the temp values are set this low,

I have the same issue with my new G570, anything i can do to solve this proble?

I try THIS BIOS (v1.09) and G570 is silent, but only to 55C, then fan start...and can't stop. So fan problem can be fixed with newer bios release.

Still no solution for the noisy fan problem?

NOTHING AT ALL .. LENOVO does nothing to fix problems that is really bad support

What makes you think it can be fixed ?

BTW here the thread about latest BIOS for G470 / G570 :

Hi all,

Have had my G570 for about 2 weeks now. Today I was using it and noticed it felt hot. Running coretemp I saw the temperature was higher than usual (it was around 65c)...

I then ran a cpu stress test to see if the fan would kick in and it did not... the temp went up to 90c and I stopped the test and rebooted. Fan is working okay now. 

I have two questions:

What could cause the fan to stop working all of a sudden? I have had laptops that the fan would not kick in after standby but after testing my G570 it appears to work out of standby just fine. Just a freak occurcance?

When the fan kicks in it never turns itself off... even after cpu usage has gone down and temps are back low. Is this normal?

My G570 is using BIOS v 2.14 which is newer than the BIOS on the driver downloads (2.09). What's the deal with that?

Shame on Lenovo pathetic support.

So is this something to worry about or is it just a annoyance?

Is there a BIOS fix in the works?

I'm having this issue as well. My G570 came preloaded with BIOS 2.14 and I can't roll back to older versions to see if it still happens.
