Changes made...fan airflow reversed so that cool air intake is at the bottom, water pan at the top, fan blowing across water pan (GQF style). Hatcher trays on the bottom.
Everything got cold during the modifications, and I added a couple of room-temp trays as well, so I won't be too concerned until 12 or so hours have passed. Right now turner tray (3rd position from top) is at 99 and hatcher is at 95. While I do want a temperature differential, that's a bit much. I believe it's just because the thermal mass is not up to temp and the thermometer is a slow-acting model.
