Physical model of computer

I'm trying to model a computer w/ enclosure using the 2-resistor in series for the computer and defining the air properties and enclosure dimensional properties using a constant volume chamber. I'm getting the same temperature before and after Rconduction_CasetoAmbient which doesn't entirely make sense. I've verified that my thermal masses are correct. Has anyone modeled a computer w/ enclosure before? I didn't see anything on the forum.method

I recall this quote, from Norbert Wiener.

https://www.goodreads.com/quotes/8157292-the-best-material-model-of-a-cat-is-another-or

“The best material model of a cat is another, or preferably the same, cat.”

Surely that would apply here too. :)

Hehe, excellent. Got it. Thank you.

I'm curious why you you would get 50 before Reconduction_CasetoJunction but 40.28 after that on the riht side! I wanna know what is different between Reconduction_J2C and Reconduction_C2A?

Also, have you seen this example? maybe your network has not been modeled correctly:
