I plug the center hole in the snowflake and run the wiring out the back instead of thru the hole. This keeps direct drafts from the power supply off the bed and improves temperature stability. There was a thread pertaining to this recently and drafts were causing dimensional issues for some users with a stock machine. I've never encountered the issue myself, but never allowed for the draft to occur either.
