Im afraid im not very familiar with the tubing your using RE kinks. I guess the angles are just too tight

Its a shame you cant expose the tubing to as much ambient air as possible though rather than running it straight into the lions den.
But then again perhaps dropping it straight through is the way to go. doubt it would make much difference given the lengths of tubing involved and flowrates.

They have really good waterchilling systems for the cold water tanks that are getting more and compact. Although they are still not practical for desktops yet! Maybe if you want a coldwater fishtank and a cold computer...sorry just being silly!
