Hi, I have a MES 30. Over the years I have ran the probe wires through the top vent as well as the door.
In my opinion It does not matter. What matters is where you put them once inside the heat chamber. Last spring I put some probe ports in the side of the box. This was done with 1/2 inch brass lamp parts. The probes I use are straight.
