Looking for Thinkpad Fan control (tpfancontrol) for Linux

Hello,
I am looking for Thinkpad Fan control (tpfancontrol) for Linux... so that in the same way I can start the program and control the fan. I dont use Linux very often and am a total novice, i.e. I cant program or enter anything at the command line, i.e. use it like Windows.
Appreciate any help.
Louis

thanks!
I went there, downloaded the file, saved it on my HDD on C:\ , once as "tpfancontrol" and once as "tpfancontrol.php", as I wasnt sure which is right... (and *.php was the standard save option).
when I rant Knoppix, I clicked on the file, nothing happened.
I presume from what I saw on the webpage that it needs to be run from a command line with some knowledge of how Linux works? As I mentioned, I am totally clueless w.r.t. Linux....
Any other ideas?

I highly doubt the script will be in PHP so it's extension probably shouldn't be that.

I thought so too, which is why I saved it without extension as well... but that didnt do anything either...

since its a script you have to first make it exectuable. Secondly you have to make sure your kernel is compiled properly with the right modules.

But is it a PHP script? Or is it something more conventional? I didn't think PHP scripts had access to hardware monitoring etc.

rriiiight...
you mean to say I cannot just click and go? I'll repeat: I know nothing about Linux, but have a Knoppix CD that I would like to use to get to know Linux... but without the fan going constantly...

Err... surely the nature of script is that it doesn't need to be compiled. Usually scripts are dynamic.

Yes but if he is having problems running the script, chances are he needs to make it executable -- chmod +x scriptname

If I was you, I'd make myself a little more familiar with Linux before I'd start playing around with the hardware.
Anyway, the BIOS controls the fan even under Linux. I have around 3500rpm, which is more or less the same as in Windows. The tpfancontrol script doesn't lower the rpm.

Surely the only way to get to know Linux is by playing around.

Yes, sure, but that's not my point. It's just that I don't think that software that could brick your laptop is a good place to start learning. Quote from the thinkwiki article linked above:
These scripts rely on undocumented hardware features and override nominal hardware behavior. They may thus cause arbitrary damage to your laptop or data. Watch your temperatures!

Yer, good point.

The first line of the script reads:
This means it's a bash script.
Linux doesn't differentiate suffixes so you can leave it as a .php if you want, but it would just look strange considering it's a bash script.
As techflavor said, you also need to give it execution permissions by issuing something along the lines of:
chmod +x scriptfilename

Here's what I did--
saved tp-fancontrol to /usr/local/sbin/tp-fancontrol
chmod 755 /usr/local/sbin/tp-fancontrol
added it to /etc/inittab so it always runs, and is restarted if it dies
Code: Select all
fc:2345:respawn:/usr/local/sbin/tp-fancontrol
Note that I did NOT use the /etc/init.d and tp-fancontrol.conf setup.
Also, here is a script which reports on the current CPU frequencies, CPU temperature, and fan speed:
Code: Select all
#!/bin/sh
FAN=`grep speed /proc/acpi/ibm/fan | cut -d: -f2`
extra=`perl -ne 'm/^EC 0xc0: .(..) .(..) .(..) / or next; print hex($1)." ".hex($2)." ".hex($3)."\n"' < /proc/acpi/ibm/ecdump`
CPUT0=`cut -d: -f2 /proc/acpi/ibm/thermal| cut -d' ' -f1`
C0F=`cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq`
C0FG=`expr $C0F / 1000000`
C0FS=`printf "%3.1f" $C0FG`
C1F=`cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_cur_freq`
C1FG=`expr $C1F / 1000000`
C1FS=`printf "%3.1f" $C1FG`
echo $C0FS $C1FS
echo $CPUT0 C
echo $FAN rpm
On my Z61t, tp-fancontrol lowers the normal fan rate of around 2800 rpm to imperceptible (reported as about 1600rpm) when it's not running hot.

I just tried running tp-fancontrol on my T60 and it made the fan run much faster. Any thoughts about what's going on? Is there some way it needs to be configured? I'm pretty new to this Linux stuff.
