I got a similar problem. I got a Lenovo Thinkpad Edge
and just installed Fedora 17
but somehow I'm not able to change the fan speed
How do you control the fan correctly? I'm asking because it seems that it's not
controled correctly in auto-mode:
Adapter: Virtual device
temp1: +66.0°C (crit = +105.0°C)
Adapter: PCI adapter
temp1: +66.8°C (high = +70.0°C)
(crit = +100.0°C, hyst = +95.0°C)
Adapter: ISA adapter
fan1: 598 RPM
I can easily heat the CPU temp up to 75° with the fan still idling at 500 rpm. So what I want is to be able to manually set the fan speed to maximum speed.
So far I tried:
$ cat /proc/acpi/ibm/fan
$ sudo echo level 7 > /proc/acpi/ibm/fan
bash: echo: write error: Invalid argument
For this to work I created the file /etc/modprobe.d/thinkpad_acpi.conf with
"options experimental=1 fan_control=1"
But as you can see, it's not working. So how do I change the fan speed?
