		+	== tp-fancontrol for X300? ==
		+
		+
		+	-- tp-fancontrol works for my X300, though I have no idea if an how I can change the code so it suits my model. I especially wonder about the levels in tp-fancontrol. Why don't you use level 1 for example? Can I only select 4 levels as in the code, or can I add all? At level 1 the fan is not noticeable (does it run at all? - cat /proc/acpi/ibm/fan shows "speed: 1820" at "level: 1", but also sometimes the same speed for level: 3, I therefore don't know if I can trust that information). Secondly I would like to know if I should adjust the min and max thresholds? Does anybody know which ones are good/safe for the X300?

		+	The script works fine for me except that occasionally and for no reason (i.e., even when my T42 is idle) the fan will suddenly accelerate to level 2 for a couple of seconds, decelerate to level 0 for a couple of seconds, and then accelerate again. This fast/slow fan behaviour then continues indefinitely. The only way I can stop it is to stop the script and start it again.
		+
		+	Any tips/advice much appreciated.

		+	== Improvements for t60-fancontrold ==
		+
		+	Hi Nick,
		+
		+	I made one simple improvement, which allows the fan to run disengaged (fastest) when the temperature is really critical. I need that because whenever I start a really heavy multithreaded compilation my machine eventually shuts down to protect itself, with this in the log. and I think I may have corrected a small bug in the code where it tries to disengage briefly.

		+	One problem I'm having is that my T60p seems to have different thermal zones than your T60, since my fan immediately maxes out due to BAT0. With no particularly great load, I am seeing

		+	t60-fancontrold: INFO: Temperatures at startup are: 58 40 36 78 50 -128 27 -128
		+	t60-fancontrold: INFO: Additional thermal sensors found. Temperature values are: 41 56 56 -128 -128 -128 -128 -128
		+
		+	So I need to figure out how to account for that.
		+
		+	Some further improvements I would really like to see:
		+
		+	* set the frequencyc scaling governor to powersave or conservative before the temperature becomes truly critical
		+	* adjust for the new kernel docking station support, since /proc/acpi/ibm/dock is no longer supported
		+
		+	I'd be more than happy to work with you on any of these.
