If they do then the hardware designers failed miserably.  Generally
what I find is that when you first power on the machine the fans come
on full.  Then the bios takes over.
What happens in the case when the power supply is going flaky and
machine glitches on startup and doesn't fully boot?

If you pull the bios chip and then power up the board and the fans
don't come on full then I would find a different manufacturer since
that one is just waiting to cook itself in a crash.
