The chiller block kev used was a simple "U" shape inside the block which yielded very little surface area. My system has a similar setup but is more like what airspirit's design describes with two separate loops, the cold side has no radiator. Using the same pelts kevin used ,5V pelts pumping 50W (x2)I can keep my CPU right around ambient with this setup. The water is below ambient, but I rarely get any condensation and I have critical points insulated.

I am redesigning my blocks now because it now looks like my flow is not even. I will try to remember to take some snapshots as I go and will publish the finished product in a thread here for all to see.

My goal has never been subzero cooling, just wanted to keep the CPU and NB at ambient or thereabouts. I could get some bigass power supplies and huge pelts to get cooler, but not worth it. These 5V pelts run fine off of a standard PC power supply and work well for this purpose. My electric bill went up $4/month when I put it in use.

Cova, the flaw in your design above is that you are using the one loop. No way water can change temp. that fast.

For these chiller blocks to work, they need to have a large amount of surface area exposed to the water in the cold loop. If setup properly, they can be effective.
