I can't comment on the Thermochill, but I've been using an 8 foot length of 3/4" diameter copper tube as a radiator for about a year now on an undervolted, stock speed Athlon XP 2400+. My goal is silence, not performance. The copper tube is laying on the floor in back of the computer. My CPU temps run about 20 degrees C above ambient under load as reported by motherboard sensors. The motherboard sensors' results are probably not accurate, but do seem to follow the temperature changes in the room. Higher summer room temps mean higher CPU temps.
My first try at a passive radiator was a variation of the copper tubing mounted in a chimney. The chimney didn't seem to make any difference in temperature, not even when I added a fan to the chimney.

Hi Joe,
Thanx for you input. found ur tower over at spcr. looks very interesting! giving me new ideas!!
mind if i print out for reference?
Do you have a rough idea of wat kind of thermal output you have from ur undervolted Althon? Cos from data i found, the 3.2E can reach 100++W of heat output. My concern is that not nuff heat can be dissipated.
Was lookin at this(
