The fan that comes with that Zalman flower heatsink can be run at one of two
speeds using the little fan mate speed controller that is attached to it.  I
think that you have yours currently set at the low speed setting.  Change it
to the higher speed setting and see if this helps.  This is also a very
large and heavy heatsink, so it will be important to make sure that you have
it properly mounted, especially in a tower case, so that the weight of the
heatsink isn't causing it to tip slightly and make only partial contact with
the CPU's core.

The XP3000+ should be running on a fsb of 166 (sometimes shown as
2x166=333), and the processor's actual core speed is 2.16GHz.

The Radeon 9700 Pro and up cards tend to have slightly wimpy heatsinks
compared to their heat output.  While they are indeed cooler than comparable
Nvidia graphics chips, they really could have gone a with a bit beefier
heatsink.  What this means is that in a case that tends to build up heat,
the high end Radeons can overheat.  You mentioned in the forum you linked to
that you might have your computer case in a cabinet like enclosure, which
makes me wonder if the inside of your case is getting warm and whether this
is contributing to overheating of the CPU and/or graphics card.

I can't tell what that drive bay fan system does.  Does it actually draw in
fresh air or does it just blow air onto your drives?  In any case, it
doesn't look like it really will direct much air onto your critical hot
components, the CPU and graphics card.

Does your case have an exhaust fan on the back other than the one built into
the power supply?
