If you haven't roasted yourself out of the room yet - you haven't gotten it up to temperature
  I don't think the fan will even be necessary once you get that stove up to 450+!!  I think it would be a good idea to get that thermometer to put on the top middle stone, at the least.  Do you have double wall connector pipe?  If so, then the only way that I know of to monitor chimney temps is with the probe thermometer (if you want to).  It is as simple as drilling a 1/4" hole in the pipe where you want it, and inserting it in the hole.  It "seals" itself when you install the thermometer.  You DON'T want to do this in your double-walled insulated chimney - only in the connector pipe (the pipe that comes directly out of the flue collar).
