Please explain
What exactly is meant with `the above` in the "Supported models"-section ?
The above was successfully tested on the following models:
Because I haven't tried everything that is above that section, but am probably going to add my fan-specs anyway...
Z61m is the same like Z60.
The kernel 2.6.18 ibm_acpi 1.12a does not allow speed command. but with direct ecdump it works. the displayed fan speed changes. (But i dont notice any noise difference)
On Z61m and Kenrel and unpatched ibm_acpi from 2.6.18: on Start the Fan is disabled :( speed 0. with echo enable > fan the fan goes to maximum rpm of 2400. (Temperatur goes above 78°C .. Bad)
On Full CPU Duty: Mode RPM 0 0 (fast switch) 1 2257 (slow switch, 5-10s) 2 2257 3 2664 (fast switch) 4 2699-2719 5 2800 6 3400 7 3284 (100%load cpu temp 68°C) 8-F same as 7 0x8F 2600 !! 0xFF speed is not chaning anymore ? (not measurement ?) 0xCF 4200 (very slow chaning.. 30s for spin up)
(perhaps this table helps a little bit.)
disengaged mode reset automatically
For some reason, whenever I issue command echo level disengaged > /proc/acpi/ibm/fan, the mode is reset to auto ("by hardware") in few seconds.
Thinkpad T60 Ubuntu Gutsy
root@Thinkbaby-Ubuntu:~# uname -a Linux Thinkbaby-Ubuntu 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux
I have also added "options thinkpad_acpi fan_control=1" to /etc/modprobe.d/options.
Any idea?

Yes. Take such questions off thinkwiki and into a proper ML, like linux-thinkpad, and I will try to answer them.

X61s
On my X61s with Ubuntu 7.10 i've got speed about 5950 in disengaged mode
