I wonder if the heatsink is poor, if it isn't mating very
well with the processor, if the motherboard isn't reporting
temps correctly (accurately), or if you have a very high
ambient temp or poor case ventilation.
I've a A64 4000+ here that didn't idle over (I forget the
exact figure as it was soon thereafter, overclocked) about
40C, and even overclocked it never reaches 60C. It is
quietly cooled with an Arctic Freezer Pro 64 (think that's
the correct name) which costs roughly $20-25 and is
reasonably quiet running at full power, made even quieter if
your motherboard has it's own fan control circuit which it
would seem to since you wrote that the rise in CPU temp
makes the fan noise bad (otherwise getting CPU temp down
wouldn't change the fan speed/noise).
If the motherboard is reporting CPU temp wrong you might
check on a bios update for the board, hoping they had
corrected such a flaw. Otherwise you might pull heatsink
off and clean off original thermal interface material and
reapply a fresh thin coat of grease, and if the case needs
alterations for better airflow, that too.
