That ' s only about double I did , not that bad PI do believe though that DMM runs the standard no refunds policy , so sucks to be him I guess xD <| sep |> One question about the testing methodology Wouldn ' t the temp sensor pads used in this test contribute to heat transportation away from the measured areas , thus limiting the heat buildup effect ? In the video , uLelldorianx say that trapped air could be part of the problem because of the low heat conductivity of air . Well , if trapped pockets of air is the problem , then applying these thermometer sensor pads could affect the measurements since it would possibly act as a medium for heat dissipation and thus momentarily alleviate the trapped air as insulation issue .
