North of the power supply hole and slightly north of the fan there is a spot in my bator where it reads almost in the 97 range! It's basically right below the vent hole. I'm using my Brinsea spot check probe thermometer as my source so i'm confident with it. But i will move my probe to the corners and other semi middle parts of the bator and my readings are in the middle 99 range. Granted when i got the bator i changed the dip switch down one step since my first incubation was ran at almost 101 when i first bought it. Just didn't know if you guys experience anything similar with your 1588's. Did the same thing when it was 90 outside and is doing the same thing when it's 19 outside. Its about 69 to 70 degrees in my house right now and i thought about bumping it up to 72 but then i thought it might make the cold spot go away but the rest of my bator too hot? Thought's guys?
