S270 / 1013 - Change FAN on temperature?

Does anyone know if it's possible to change the temperature which sets off the FAN?
Using the internal sensors I've found that the fan starts around 50C. When in Idle mode, my computer sits around 49-51C which makes the fan go on and off every now and then. I simply hate the sound of the fan running. According to other posts here, it is possible to change the S260.

But I've been unable to find similar posts regarding the S270.

 

ohh i totally know what you mean, mine goes on and off too.. it hits 48* or so and shuts off, and goes back to 50* within a few seconds and clicks back on.. really annoying.. but i dunno how to fix it either sry :-(

 

Ask for new BIOS with higher thermal Trippoint.

The Temp is set in The ACPI DSDT ... on a windoze box you won't be able to change this, on a Linux box you can rebuild the DSDT and load it at boot.

 

Whats better for battery life? And would it make much of a difference? Running the fan less and having a warmer cpu, or running the fan more but having a cooler core?

 

I guess the CPU running warmer will not affect battery life. The CPU will run at some dynamic comsumption of watts and heat is just a side effect from this. I don't know though, if setting FAN ON temperature higher will just move to problem to start a little later, or the higher level will actually not be reached as often because of roomtemperature "cooling" down also.

Stephen: How-to? Do you know somewhere with a guide for this?

 

Linnau:
Can you check if the CPU temperature behavior is the same in your notebook?
i.e. that after some time, any cpu usage causes the temperature to suddendly rise, and when the cpu usage is over, to suddendly fall?

Please download Mobile Meter (MM) from here: http://www.geocities.co.jp/SiliconValley-Oakland/8259/release/0310/mm0310.zip

In the MM options, shorten the ACPI-temperature and frequency update interval to 1 second, to better see the graph.....
Then, for example, open a cpu consuming program or simply move a window.... in my S270 this means the temperature having sudden bounces, almost like the processor frequency.......

 

I have somewhat experienced that as well. If the CPU usage is high enough to make the speedstepping go high, then the temperature rises suddenly. But it does not happen every time. Mostly when I'm around the 50C which is where my Fan goes on. It is clearly some kind of bug in the thermal software.
Maybe you even have the "fan always on" problem as well.

Btw. I use Notebook Hardware Control (Guess it does about the same thing as MM)

 

Yes it's the 3rd time I turn it on and it already has the fan bug.
Last evening I reinstalled XP (because hte bundled one was german and I'm italian) and the fan was normal.
Did the installation and proper config on battery, then went to sleep and let the notebook recharge.
Today , fan always on

Mine has got a wstern digital 5400rpm hard drive, its got a REALLY ANNOYING vibration/hummmm which shakes my head... but I guess I've only got to get used.

Otherwise, it's perfect

I'll try when I have time and enough braveness, to take it apart down to the CPU and spread my thermal paste, I'm sure I can do bwtter than MSI fab at this....

 

Uhm... I've just rebooted and the fan instantly stopped and now it's off... it's dointg the same on/off trick I explained.

I think it's because of that temperature steep rise/fall.
Whenever you do *anything*, it will cause a 2/3 degree increase (at least), which in turn will trigger the fan for the time strictly necessary to cool down these 2/3 degrees......

May be this can be solved with some better-spread thermal paste.......

and see if this works for you.

 

I havent't tried it yet because the fan turned off on its own, and now, strangely, it behaves normally, apart from that occasional on&off stuff.
Anyway, check what EC bios version have you got.
I have got version 1.8

 

Sorry, I do not know what the EC bios is or where to find it.
What is it exactly it does?
