i read about the golden rod...
seems to me like its meant to keep the temprature inside an enclosure slightly warmer than the outside temp which prevents the walls (and other stuff in the enclosure) from getting below dew point, preventing condensation. the problem here is the pipes are providing the coldness

i guess the golden rod could help by heating the outer layer of the insulation on the pipes above dew point...
im starting to think that watercooling with such cold water is a waste of time. all that really needs overclocking is the graphics card, so i should just slap a 226W peltier directly on my 6800GT
hopefully ill see a nice extreme overclocking example with the 6800GT before i get around to it to see if its worthwhile.
room temp cooling is so much simpler heheh.
