Makes sense, nick...have you tried rearranging the ribbons so that the draws become more even across all of the power distro scheme? It should be possible, if you more or less know your module draws, to snake things in there around so that everything becomes even, then if the P/S for that zone is still running too hot, you'll know that there's potentially a problem with the P/S itself. If not, though, you've gotten your current draws set up properly with those adjustments.
