Ubuntu: fancontrol on no pw-capable machines



Question:

I've installed Ubuntu 13.4 on my Alienware m14x and noticed one thing, cpu gets as high as 70 degrees centigrade (with nothing resourceful running) and cooler doesn't respond to that, just stays calm and quiet. How can I change that?

fancontrol couldn't help me - pwmconfig says: "There are no pwm-capable sensor modules installed"

upd: I've managed to control fan speed with i8kutils. By running i8kctl fan 1 2 I've managed to speed it a bit, but I can't get to the highest possible speed. CPU still gets close to critical temps.

upd2: I think I've managed preventing the laptop from overheating by installing bumblebee, but still couldn't find a way to run the fan on its highest possible speed, so theoretically it still can get to critical temps. I'll be testing that. Also apparently bumblebee installation removed i8kutils so no way to control the fan manually anymore.


Solution:1

The marked 'maximum' speeds on fans are theoretical, and can be rarely reached practically. Something that 'may' help is: Open the chassis, take the fan out and clean it free from any dust in there. Make sure there's proper ventilation so that dust doesn't block the airflow.

Keep Bumblebee installed and let it control the fan speed.


Solution:2

I have dell inspiron and I was not able to install AMD grahics drivers for my graphics card after installing 13.04 . For some reasons unknown to me, the driver was not available and it was causing my laptop to goes off because of over heating. I suggest you to check if your graphics driver is properly installed and working properly otherwise to resolve this I have downgraded to 12.04.
