I guess you mean that the fan is disabled. It may take a few seconds
if there is no heat sink attached. However, with a heat sink it will
take several minutes until the CPU overheats.
As an example, take my first-generation (i.e., power-hungry) Athlon 64
3200+. It recently hung before reaching 35 degrees Celsius, so the CPU
fan was not spinning (I had set fancontrol to turn the CPU fan on at
35 degrees C). After about 20minutes I noticed it. The machine had
not shut itself down, but on reset it did, and when I started it again
and entered the BIOS, the temperature was 83 degrees C; quite hot, but
apparently below the emergency shut-off.
However, that was with the CPU frequency clocked down to 800MHz (and
the appropriate voltage reduction), when running at full speed it
would have reached such a temperature much faster, but still in the
range of minutes rather than seconds.
As for the OP, if I understand his problem correctly, he will have to
lower or turn off the BIOS CPU fan alarm, or use a faster-spinning
fan.
