It might be a fluke but I unscrewed the 6 mainboard screws just enough to remove the holdown tension as a test.
Screwed in the coverplate and all the covers to complete the laptop.
Ran CB r23 again.
I got the highest score yet I seen my FW16 do.
Im going to do another run and see what happens.
Do note the thermals of the cores. Still very unbalanced.
It’s too soon for any conclusions, I will do more testing.
