The 7000 AlCu should be plenty of cooling for your Athlon XP, assuming you 
are running it at the default voltage.  It looks like your motherboard 
should support this heatsink, as well, though you might want to double check 
that there isn't anything around the area of the CPU that might be 
preventing the heatsink from sitting on the processor in a level manner. 
This is a very big heatsink, so it is easy for some component to be in the 
way and keep the heatsink from sitting all the way down, flat, on the CPU. 
You may also want to double check that you installed the heatsink properly.

Did you plug the fan into the CPU fan header?  Assuming that you mounted the 
heatsink so that it is getting good contact with the CPU, the problem may be 
with the CPU fan monitor, as the excerpt from the instructions that you 
quoted above suggested.  Turn the fans speed up to full, at least until you 
can get into the BIOS to change the alarm settings.  If this still doesn't 
work, you could try another 3-wire fan (your old heatsink fan, for example) 
in the CPU header and plug the heatsink fan into a different fan header. 
Again, this would be until you can get into the BIOS to make some changes.
