But okay, let's assume it is protruding out. As you see in the video, the insulating material is flexible tape. It will bend and cover over things. So even if the TC is protruding out, the air pocket around it will be small. Furthermore, even when you make a huge air pocket with a pipe and you run water 34 deg C cooler than your target through it, that makes no measurable difference. So I suggest: 1. You stop fretting about this. OR 2. You propose some test that I or someone else can do to prove or disprove your hypothesis. If you don't like my tent, what do you propose? OR 3. Get a TC and try it yourself. It should not be necessary to get an entire heat exchanger to test this one hypothesis. The experiment should be simplified to include only the specific details being tested such as whether an air pocket can affect TC performance. By the way, if the TC is protruding off the edge of that nut, I expect that would bend the TC into an L shape. These are flexible wires not rods. - Jed
