What I would say is important is following good practices and doing a second pass to double check all screws. I use the “star pattern” method like for a car rim or drum head. I also started at the core on both attempts as per Der8auer’s recommendation.
The tension of the cooler screws must of just slightly shifted the positioning of the cold plate at the core. Which gave me the extra 1/8 to 1/4 turn on just two screws.
I measured flatness of the cold plate and it was well, flat. Light / razor technique.
My only assumption at this point in time is that the tolerances are simply too fine. I’m curious how the cooler will also behave with expansion and contraction as I use it.
I have a feeling without good pressure, there is a microscopic gap at the core of the die.
Maybe there will be a revision. Only then or if my hotspot temps creep back up will I RMA it.
