Right. > this mean that when you increase the power, and if temperature grows much > more that before, something anomalous is happening ? > Exactly. However, there are some open questions about the IR camera and the color. So we cannot be sure the temperature really is getting higher. If the authors can confirm that the temperature shown in the internal thermocouple is also rising, and that the colors are transitioning to ones indicating a higher temperature, then yes, we can be sure there is an anomaly. This is true even though there is only one calibration point. That is inadequate, but it does not preclude certainty. > Either excess heat, or some external blanket effect (increase of thermal > resistance)... > but convection does not diminish with heat? > The device is open to air in a reasonably stable environment. I do not think that a change in convection on this scale is possible. - Jed
