I assume that means you could always touch them without getting burned....



We were going to publish this today anyway....Here is a Temperature plot that we did based on a 40AMP continuous load @12 volts. We measured 2 data points inside the SPARK (right on the mosfets & on the Capacitors) and 2 datapoints outside (ontop of the heatsink & on the bottom of the plastic case). I am working on the full write up, but this should give you a good indication in the meanwhile.
