Re: Replacing G570 fan

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.

Re: Replacing G570 fan - Noisy fan that runs most of the time even though laptop is cool

 

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.

 

Regards,

JimBob

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)
   
Temperatures   
CPU Package    44 °C  (111 °F)
CPU IA Cores    44 °C  (111 °F)
CPU GT Cores    42 °C  (108 °F)
CPU #1 / Core #1    42 °C  (108 °F)
CPU #1 / Core #2    44 °C  (111 °F)
GPU    34 °C  (93 °F)
GPU Ambient    35 °C  (95 °F)
HITACHI HTS545050B9A300    33 °C  (91 °F)

 

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

Re: Replacing G570 fan - Noisy fan that runs most of the time even though laptop is cool

 

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.

 

Regards,

JimBob

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 ?

 

Regards

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