Boot is fixed. acpi snooper was loaded by mistake.

Let's add to ACPI docs -> troubleshooting:

29) Trap during OS2LOGO
       do you upgrade from ACPI 2.x to 3.x?
       check snoop.lst, do you boot old acpi snooper? it is not used in ACPI 3.x


----------

There is other problem.

If boot without ACPI then coolers are silent. Look at BIOS setup photo. 
If boot with ACPI 3.05 then coolers are loud.
