I'm curious as to why my water/antifreeze solution is so much colder than my cpu is, and also why when my water/antifreeze solution gets colder my cpu doesn't. For example I started up my cooler and let my water get down to -14c and then started my computer up. In windows at idle my processor was at about -5c (fluxuates alot for some reason).

After a few hours my water temperature had gotten down to -20c but my cpu temperature was still about the same (-5c fluxuating between -2c & -7c)

Anyhow I was curious as to why there's such a big difference between my water temperature and my cpu temperature.

For those who want to ponder I'll give a description of my system:

dehumidifier with evaporator submersed in 4 gallon plastic ice chest full of water/antifreeze.

Plastic Ice chest contained in a 10 gallon styrofoam cooler with about 2 inches of spray polyurethane foam in between the 2 coolers.

700 gph danner pump. Inlet side left bare, outlet side connected to 1/2" tygon 3603 tubing insulated with 1/2" rubatex tube insulation.

5 ft of tubing to a swiftech mcw462-uh waterblock which has been insulated with rubatex insulation tape completely to the motherboard (the tape comes off the water block and seals to the motherboard).

5 ft of tubing from the waterblock back to the reservoir.

The pump is on one side of my evaporator and the outlet tube from the waterblock is on the other side of the evaporator in the opposite corner.

I think this is pretty standard as far as water chillers go, but I guess the temperature difference may also be pretty standard also?

Any Ideas?

Thanks,
