Replacing G570 fan

[damo_]

Is there any answer to this problem yet..?

I'm considering disconnecting the fan as it is really annoying when I'm in a quiet enviroment.

If there is no solution found soon, I will return my noisy one week old G570 to BB.

The noisy fan becomes very tiring after a short while.  Other that the lack of an HDMI port (which I can easily live without), the noisy fan is the only thing that I do not like about the G570.

Lenovo G570, i3, HD6370

Fan start at ~55C, and he works even if temperature of processor is ~44C. (only internet, no games).  After 30-40 minutes fan stop's (to much). If i restart notebook when fan work's (CPU - 44C), he is quiet to 55C temperature. BIOS ISSUE, Lenovo must fix time of fan stop after lowering the temperature.

Some data from Aida64 (fan work's at full speed):

 
Sensor Type    CPU, HDD, SNB
GPU Sensor Type    SMSC EMC2101  (ATI-I2C 4Ch)

In Lenovo Managment Console I have "energy star" profile, in amd powerplay i set best energy saving profile.

Hi All,

I just wanted to mention that I disabled the hibernate mode and now the fan behavior is acceptable.   I am going to hold on the laptop for now and keep monitoring the fan.

how do you disable that hibernate mode ?

there is not such option in g470 BIOS 40CN22WW(V1.09) ,

And I dont see how can this affect fans...

Also do you know a way to monitor fan RPM and cpufreq ?

Try unlocked bios, you can set when fan must start (temperature of start).

I am afraid this will void the warranty isnt it ?

anyway I am running a g470 not g570

[bananaman1]

You can always flash oryginal bios . About G470 go to first link. Bios files for G470 and G570 are the same...so...

what If something went bad on flashing unsupported BIOS ? is anyone running custom BIOS here ?

[bananaman1]

I have custom bios...

You can recover it. Look on google "insyde bios recover" or something....
