That's a good thought, but it's really one end that is hotter than the other so the pattern is much broader than the zig zagging of wires. It's a gradient but it's not well defined at all. And besides, 15 degrees is ridiculous. It's really like one hotspot (not centered though) and then a medium zone all around that and lower temps around that. A heatmap would show it best. I think part of it is due to the surface contact or lack thereof, which I am trying to resolve.
