Maybe the cooler itself is less restrictive like you're saying. It is 1" thicker than the factory one. Also - the factory one has better cooling air flow than what I've done so far. So yeah - more oil flow and less airflow = hotter for new cooler. That's my guess. I need to take some temperature readings.

There is also a small restrictor in one of the factory lines.
