Yeah, since your system isn't booting to the operation
system, there is no ACPI-Halt power managed state so the CPU
is running at higher heat than it might otherwise, so the
thermal sensor kicks up the fan speed.

Either that, or your fan is dying.  Watch it to see if it
spins faster, slower or same speed as noise goes up.  Slower
or same would be a dying fan.

What's the history of the system?  What's it like?

Details = good start to a thread

You might check the PSU and battery voltages with a
multimeter.  Unplug PSU from AC for a few minutes and retry
it.  Clear CMOS if all else fails, and check the board for
vented caps.  Maybe none of this applies, we don't have any
background info on the system.
