Hmm, I found nothing interesting in your acpidump. It seems that there are no ACPI fan/thermal devices in your bios. In fact, many thermal/fan are ACPI transparent and they are controlled by the bios or something else like hardware monitor. Is there an obvious overheating problem on your system?

Still no data in /proc/acpi/thermal_zone after switching to ACPI 2.0 in the BIOS. The requested output of acpidump is attached.
