Ah, have to check that tjunction info when my bx2 box is back up. I wonder if my budget e4300 is different than the prior c2d chips somehow and is therefore not in their databases (or whatever) yet.
If I recall, coretemp was reporting temps below ambient at idle so I was tending to believe TAT. I only had the system assembled to test for a day prior to tearing it down to fix the ugly p180 cablegami/airflow issues so I don't have much time in with it yet. Still have a ways to go before it's back up. Once it is, I'll check if the discrepancy for my application is indeed a consistent 15 degrees.
