I think EKWB could have handled the situation better for owners of the CPU block. But for monoblock owners I think the solution is about as good as we can hope for. It would be great to get the upgraded kit sent pre-built, but they would most likely need the old units cross-shipped. Nobody wants to be without their computer for an extended period of time. Obviously, I would prefer they got it right the first time, but credit goes for trying to make things right.
I've requested the upgrade kit, and EKWB were super helpful & quick in getting it shipped. Fortunately, I haven't built the system out yet, so I don't have to tear everything apart to get to the block. Unfortunately, I don't have the patience to test the system without the upgrade, so I can't provide any "before" numbers. However, I will follow up with the temps once I get the new plate installed.
