For a while, I've been using a workaround that would "echo level 7 >
/proc/acpi/ibm/fan" every login to keep it maxed out - unfortunately
this would not be high enough while running anything 3D, and my computer
would often overheat (to dangerously high, lap SCORCHING levels) and
shut down.

My new workaround involves "echo level disengaged > /proc/acpi/ibm/fan",
and that boosts my fan levels from ~4500 to ~5700. Thats a lot of
missing RPM.

For reference, how to do this hack (based on
http://www.thinkwiki.org/wiki/How_to_control_fan_speed)

sudo apt-get install thinkfan
sudo echo "options thinkpad_acpi fan_control=1" > /etc/modprobe.d/thinkpad_acpi.conf
sudo echo "#!/bin/bash" > /etc/init.d/thinkfan-ctrl.sh
sudo echo "echo level disengaged > /proc/acpi/ibm/fan" > /etc/init.d/thinkfan-ctrl.sh
