This sounds like a kernel crash, the CPU spinning, and, naturally, the 
increased temperature of the now always-busy CPU causing the fan to go on.

Of course, this is unlikely to make any real difference whatsoever, unless 
the suspected kernel bug is in the ACPI code that you've disabled. 
Otherwise, none of this is likely to prevent triggering the suspected kernel 
bug. The CPU high temperature is the symptom, not the cause.

I had this initially happen on one of my laptops after upgrading to F11. The 
laptop would be unstable, and regularly crash, lock up, and spin the CPU, 
causing the fan to go on. After installing the latest kernel upgrade, it 
hasn't happened again, so far.
