Always up for some science, what do you wanna know?
I'm in the honeymoon/testing phase, trying to find my favorite setup for it, so taking requests
I can tell you this for starters, in my opinion - without the cooling unit it is much different than a helix tube Tempest v1, but very similar to a direct tube Tempest v1. With the cooling unit it is more similar to the helix T1 and noticably different than direct T1.
If I was doing a blind Tempest draw test, v1 vs v2, I am pretty sure that I would not notice the difference... both perform very similarly and have that same signature.
Gotta say, the new adapter is the MVP though, it heats up faster and the batteries last longer - I am impressed.
