In my experience typically (but not always) if there is air in the system, you'll hear that boiling sound after shut down. And while the car is running you see spiking of temps...not so much a steady rise as you've described.
I also don't see how heatsoaking of the aluminum IC ducting could have anything to do with it.

But I can't think of anything else to suggest. Sorry.

hmm, after shutdown I do hear a bubbling sound that comes in groups.....ill shut the car off and after a minute or two ill hear brsh,bhrsp,bhrsp.........brsh,bhrsh, I thought it was water returning into the system from the overfill due to heat expansion/cooling

My buzzer never goes off, and my level is always full at the fill neck, so i figured theres no air in the system...however, is the AST supposed to be at a high point above the filler neck, because mine isn't
