Lcpiper from pimprig managed to get his temps below ambient with exactly the setup i described. check it out
HERE
Granted its not very far below ambient temps, but its a good start I think. with bigger/more powerful pelts I think it could work
see i understand how a radiator works, and i understand that the inclusion of a rad in your system will limit your lower ranges, but id think that with such a small chiller, you need to get your temps down a little in between the waterblocks heating the water and the chiller. seeing as how this chiller only cools a very small volume of water, surely it is beneficial to cool the water a little in the rad before it gets to the chiller?
can you explain why my reasoning is flawed?
*edit* nevermind i see the point about the block heating water only a fraction, hmm, so you are saying a chiller with no rad is more efficient?
