lenovo c200, cooling questions, trip points?
Ijust bought a nice Lenovo 3000 c200 laptop. Every seems to work fine except fr two things I am not sure about.
The first si the sound does not work, but I do not wish to tackle that in this thread.
The second is the fans. Now the fans seem to be constantly spinning. They are not spinning fast, they are virtually silent,so I have to put my head close to the laptop to hear them spiining, but they are spinning all the time. I am pretty sure this was the case while I was using the pre-installed windows to create recovery cd's, I never noticed them not spinning quietly.
Now what I do not understand is, they never stop, nor they they speed up either. I only have Suse 10.2 to had for installing and all the while it was installing the fans never got any faster, they still stayed virtually quiet. It got a little hot, but nothing that feels out of the ordinary, about the same as the heat output by your psu. SO I am pretty sure this is within the cpu freshold (laptop cpu are built to withstand much higher heat than a normal desktop cpu because of the space limitations right?)
I do not fear the fans dying on me, seeing as they only seem to be spiining in a very low speed constantly, both while using Windows and Linux. But I am interested in possibly keeping the machine cooler, via frequency scaling (if supported) and via the fan trip points. I looked in the proc/acpi/fan/ directory but all the files to do with trip points konqueror said were empty and were 0 kbs.
What should I be looking at to setup the cooling things I have just mentioned above? Could anyone point me towrds some relevent guides etc please. At present it is running opensuse 10.2, but I will be installing Debian Etch as soon as I have the time to do so, so if possible could the guides be relevent to debian.
The machine is a Lenovo 3000 c200, 1.6 Celeron M, 512 Ram.
Thanks in advance
Michael.
