I would be curios too. I went to radio shack and purchased their silicone based heat sink. I have a batch going now. It seems to be working, but I am anxious as I couldn't test out the set-up before putting wort in the thing. I smeared some on the sides of the probe as well as a pea size on the bottom, then shoved it to the bottom of the well.
I might try the tubing idea next time, providing I can get a bigger and more cost effective heat sink. The one from radio shack was 4 bucks for a small tube. Ill check Mcmaster.
