Depends on where your thermostat probe is, but yeah its easily possible for Flexwatt to reach 100 degrees if your probe is getting cooled off by ambient air somehow.
Try this if you have an empty slot in your rack.
Put the probe inside the empty tub on the floor above the flexwatt and control temps that way.
The only thing I can think of, now that I see where the probe is, (under the flexwatt in the shelf correct?) is to just dial the thermostat down a bit until you get the desired temps inside the tubs. If its reading 100+ guarantee your tubs are that warm too. Makes sense to me that the heat is rising into the tubs and now downwards into the shelf.
Is the rack in a cold room?
