Lenovo 3000 N100 Fan ALWAYS on!

Hi,

 

I am so tired of this notebook! I bought this notebook a year ago, and the fan settings are driving me crazy! 30 seconds off 1 minute on... again and again! And the notebook always feels cool!!!

 

This is the only notebook i know that makes such constant noise... Anyone advice? Otherwise it will be my first and last Lenovo!

Re: Lenovo 3000 N100 Fan ALWAYS on!

My 3000 N100 runs cool and the fan does not come on

very often. I use Balanced setting in Vista power saving.

High performance may come on more often?

 

Have you checked for dust build-up in cpu heatsink?

Remove the cpu cover on the bottom and look for dust

on the copper heatsink fins.

Yes, I 've cleaned the fan, heatsink and removed all dust. My CPU runs at 63°

 

Fairly cool i think, but my fan controller has a different opinion...

Re: Lenovo 3000 N100 Fan ALWAYS on!

i wouldn't consider 63 degrees at idling very cool...

Re: Lenovo 3000 N100 Fan ALWAYS on!

What can I do more? It's a clean Vista installation from the recovery cd's and ALL updates...

 

Programs running... AVG also latest updates and NOT scanning and Firefox...

 

A search for Fan on lenovo 3000 N100 shows me that I am not the only one...

Re: Lenovo 3000 N100 Fan ALWAYS on!

I would personally try removing the "thermal module" or heatsink,

clean off cpu and heatsink, and apply new thermal paste.

Use any good quality paste, per manufacturers instructions.

 

Download the service manual here:

 

http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-63486

 

Instructions for removal start on page 65.

 

This may or may not help, but it is a next step!

how do you monitor this idle temp ?

 

I used hwmonitor_1.18-setup.exe on lenovo g470 it's around 41-45C see screenshot :

just curious do you know the expected idle cpu temp ?

 

other laptop have better management according to this survey :

Re: Lenovo 3000 N100 Fan ALWAYS on!

The min and max cpu temps look pretty good in cpuid,
I think.
