chilled water is the future (for those not already there)

I agree with BillA on this. With the CPU/GPU/NB all getting hotter, standard air cooled system will soon be overloaded or very loud.
Most standard watercooled system can keep up for now. But when you start to add all the items that would have to be cooled to have a quiet system... 150 ~ 200watt heatsource is not out of the question anymore. Throw in the next gen 15K rpm harddrives, GPU's, CPU's , this heat will soon become even too much for watercooled!
Here is my heatload (may not be accurate but)
CPU 2.66 oc'ed to 3.1 @ 1.65V = 85W
GPU Radeon 9700Pro ..............= 35W
SIS 655 NB ..............................= 15W (guess)
2 x ViaAqua 1300 pumps ........= 40W
Total 175W
I have recently built myself a chiller using a dehumidifier. My goal was for 24/7 operations, quiteness, and OC'ablility. Some of my observation.
Water Temp ..... CPU temp ....... Delta
..............................no load
0c ------------------> 5C ------------> 5C
-3C -----------------> 4C ------------> 7C
-7C ---------------- > 3C ------------> 10C
-12C ---------------> 2C ------------> 14C
It would seem that the lower we want the CPU, the delta between the CPU and water temps increase. It would seem that the "cold-loss" as we get colder increases thereby reducing the effectiveness of the chiller??
