The evap probe only turns the compressor off when it senses the evap core falling into a freezing temp spread. Blend door would have more to do with your heat sucking more than anything.I ran some more tests. It's only about 62 outside. I just backed the car out of the garage and let it idle. I set the ATC to 84. The compressor ran 99% of the time. It did stop a couple of times for about 5 seconds. The metal tube coming out of the compressor, I'm guessing the high pressure side, was very cold. To the point where water was condensing on it and dripping off. I've seen condensation on it, but never dripping off.
I switched the AC to 70 and the air temp at the vents was extremely cold. At 84, the heat was anemic. I have a feeling that the evaporator sensor is not shutting down the compressor. In the ATC diagnostic mode, there are no codes.
Compressor can run all the time if A. Pressure never gets to high, B. Evap Core does not freeze.
Comes to your cooling temps, I think you are over analyzing them and expecting new parts to react same as old ones which is not true.
Also here is the 1G fan operation temps for future reference.
