Final update to this tread.
New board showed up in 3 days once support informed me it had shipped. Shipped from New Jersey to California. FedEx was the slow mover once it was in there hands.
Installing the new board was easy, followed the guide that Framework made just so I didn’t forget any steps/miss screws that needed to be loosened/tightened. It took me about 20 min to swap boards.
After booting back into my Win 11 install I ran Cinebench R23 multicore.
The delta from core to core is now less than 7c from hottest at 98c to lowest at 91c.
The improved thermals netted a jump from 14k to 15k, about a 7% jump. I ran it multiple times both with the old board and new and the results are solid.
So if you’re seeing a wide range on temps from core to core, reach out to support. I’m very happy with the help I ended up getting. It did end up taking about 3 weeks total to get a replacement in-hand, about 90% of the time was emailing support on it. Hopefully that time shrinks as they get through the pre-orders.
