Yes, but from the sound of it the original poster is referring to a AT,
not ATX board. On those, the fan is wired to the main power circuit and
comes on when the power is turned on at the front of the machine. Later ATX
models had the power managed through the board.

A corrupted CMOS may inhibit power on.

It can prevent the system from POSTing, but without a viable BIOS,
even without the EEPROM in the board it should still be able to pull
the PSU power-on pin low, turn on the power supply so at least it's
fan would be spinning and voltage levels obtainable.

Apparently not. I had a Compaq system which played totally dead and
resetting
the CMOS fixed it.

The question at this point might be, "Which fan isn't turning?".
Apparently some Compaq systems do use logic for the CPU fan control,
it may not spin but the power supply fan should still be on.

Nothing, dead as a door stop.
