waiting on the cpu to arrive tomorrow. My specs are:
Abit NF7-S v2.0 with vdd and vdimm mods
1700+ JUIHB
Geil PC3500 2x256
Maze3 waterblock, aquarium pump and radiator
I'm hoping for great results !

Flow is king. The water carries the heat away. You want a system with
as little resistance as possible. My pump may not even have enough
GPH balls to do what I want to do.

Every time your water path makes a turn or goes uphill at any point
in the system, it decreases flow. The longer your water path, the
less flow you have. I've seen as much as 15 feet of tubing using a a
computer. That's an amazing amount of tubing considering the small
spaces we're talking about. However, it was probably the only way it
could have been done in that particular situation.
Further, the waterblocks and radiators are extremely small (compared
to an automotive system), so the water spends very little time in
there anyway. Also, in an automotive system, the components actually
NEED to warm up to operate effeciently, so slowing the ware down or
reducing the size of a radiator is done to effect that requirement.
In a computer system heat *of any kind* decreases efficiency, and
needs to be evacuated at the best possible speed.

1. it was designed to run at lower revs and when revving the engines to
7k and beyond, the pump becomes inefficient and doesn't circulate the
water properly, it starts to cavitate (?) and just whips the water to
foam (not the most technical description perhaps :-)
2. With the addition of oil coolers etc, the standard radiator is more
than capable of handling the extra heat build up from the tuned engine,
and slowing down the water pump will give you extra power

This is false. In this heatpump situation, the only purpose of the
water is to move heat from the cpu to the radiator, and slow-moving water
has low turbulence and accepts less heat per time unit than fast-moving
turbulent water.
Issues with high-revving car water pumps have more to do with
cavitation-caused inefficiencies, and are unrelated to the basic point that
faster water is better than slow water. Of course a super water pump also
adds heat itself to the water, but I'll ignore that effect.

And here's another difference between car and computer waterpumps. The amount of power the computer waterpump consumes is independent of the power used by the cpu, we assume a limitless supply of electrical energy.
