Lenovo S10-3 Fan Control (Linux) and overheating

2011-03-11, 23:38 PM

Good day to everyone.

Let me describe the situation. My Lenovo S10-3 is always hot (even in idle) and uses internal fan very often. It irritates very much because fan is noisy (service found no problem).

 

Sensors: acpi-tz ~60C, core ~50C (idle).

But even fan is disabled (connector is pulled out from motherboard) temperature becomes not much higher --- approx 65-70C.

 

Now, the question: is there any way to override BIOS fan control values? (e.g. 55C="Fan on" to 60C="Fan On")

For the S10 series there is program named "Fan Control", but it doesn't work on S10-3 and this program is for MS Windows only. Can anyone give comprehensive ansver/guide how to control fan speed (or on/off temperature values) using native linux tools or special program? It might be very useful for others who experiences the same problem. Thanks.

It doesn't work, pwmconfig shows no compatible modules (even with /usr/sbin/pwmconfig editing trick).

The heatsink is not connected to the surface of CPU and GPU and this is why you said that disabling the fan doesn't make any difference in the temperature. There are two pieces of thermal pad on the CPU and GPU.They are actually unusable. Remove them. Put thermal paste on the surface of CPU and GPU and heatsink and then put a piece of copper on CPU and GPU. This will make connection between heatsink and surface of CPU. This will make the fan usefull :p . Do this at your own risk (There is no risk. But use suitable pieces of copper is very important.) Using google will help you find about this issue

I already did it (replaced default thermal compound by thermal paste with better thermal conductivity) before my first post in this thread. Contact between heatsink and chip surface is solid.

1) IdeaPad is not ThinkPad here (thinkpad_acpi module is for Supported models - bottom of the page, when loaded on s10-3 - error occurs).
2) I know how to use Google. Alredy tried many of search results.

Yes, I've searched. No specific methods for s10-3 model, but there's some info for other IdeaPad-series net- and notebooks. I'll keep trying. If something will work - I will post it in this thread.
