I hadn't loaded the thinkpad_acpi module with the fan_control argument. Done that and I'm now able to set the fan speed. Many thanks for that. I've followed the instructions at https://github.com/theothertom/thinkpad-temp_mon and no sooner had I began testing in a another terminal, the laptop shutdown but strangely without any heavy lifting tasks running in the background.

Broadcast message from root@curiosity (Tue Aug 13 14:42:12 2013): The system is going down for system halt NOW! Regarding the canned air solution, is it a one-off job to clean out the CPU heat sink or is it for a continuous circulation of air directly over the heat sink? -- Many thanks, Alphonse -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
