I do have two thermometers in addition to the unit's. Both thermometers were reading high. I added a digital thermometer/hygrometer today. The two thermometers are reading right at 100 and the digital is at 101.1.
I trust manual thermometers over digital... but if you've got two thermometers reading one thing and a digital reading high, try a regular thermometer (one that you put in your mouth to see if you have a fever) and put it in a vent hole. See what it gives you. Go off your 4 readings (hopefully that will be enough... I've had 5+ at one point).
