Ok.

You'd have good reason to get new one.

Ok, so it is the bios doing temperature control up-to 81C. At 81C, linux should start cooling it, and at 88C, linux should shutdown. At little higher temperature, hardware should emergency shutdown.

Well, try it :-). suspend.sf.net.

Fan is not controlled by ACPI. But we may be saving some memory we should not save, or something like that.
