Some interesting acpi errors there. Are you having any difficulties with power adapter/battery recognition?

Your dmesg log file shows that you are also using acpi_backlight=vendor. I'll assume its active.
My current kernel parameters are:
BOOT_IMAGE=/boot/vmlinuz-3.11.0-14-generic root=UUID=4ad42862-aaa7-4720-a8c2-7e12d4a10070 ro quiet splash acpi_osi=Linux vt.handoff=7
Out of curiosity, can you try the acpi_osi="!Windows 2012" kernel parameter? This one is a little tricky to setup properly. The relevant lines in your /etc/default/grub file should look like:
...and remember to run "sudo update-grub" to commit the changes. On reboot, post back your dmesg file again and check whether there is any difference with fan management. Also double-check your backlight controls.
GRUB_CMDLINE_LINUX="acpi_osi=\"!Windows 2012\" acpi_backlight=vendor"
You might want to consider contacting the developer to see if they can add support for your bios version.
I've just tried acers3fand and it doesn't support the bios version either, unfortunately.
