Rack or More Enclosures

[KMG]

Right now the AP enclosure has both radiant and belly heat. Cool side of the cage is 75. Probe on the warm side says 81, but I think it's more. Should I have more than a 100W thermostat on the 3" heat tape? It seems like the heat tape isn't doing enough, but it is set to 90.

Heat tape is not meant to heat the air. It is to create a hotspot for the snake to lay on. It does very little for the air. To get that dialed in you really need a IR temp gun so you know just what temps the floor is reaching.
