	Yes, unfortunately you may be right :(
	But I cannot stand W...zzzz anymore.

	However the problem is somewhat tricky.
	I try to summarise it:

	- CPU and disk temperature is generaly high (45-50 degrees) and
	  it increses up to 60-62 degrees when under heavy load (e.g.
	  kernel compilation)
	- this makes fan to work "almost" always, however:
		- it stops sometimes
		- it changes its speed according to CPU activity (I can
		  tell you from noise)
	- /proc/acpi/fan/ is an empty directory

	My conclusions:
	- temperaure and fan speed are connected (directly bi BIOS or by
	  linux ACPI management? how to check it out?
	- high temperature are unlikely related to reduced fan
	  functionality (-> design issue? Core 2 Duo is too demanding?)
