Yes, I saw that too, at the time I did the testing. I discussed this with the author of the linked review as well as the guys at Ybris, but we couldn't find out the cause. I opened, cleaned, reassembled and remounted the Ybris block several times, trying to find out what was going on.

@Arthur:
The Ambient temps were between 21 and 24 degrees Celsius during all of the test runs. The temperatures shown are the delta-temperatures of all the four core-temperatures averaged out minus the water-temperature. This is the most reproducible temperature measure in a watercooling setup.

As for the other questions, MechOz has answered those already. The Low Cost (LC) HK 3.0 doesn't perform quite as well as the copper version. This has nothing to do with the fact that the copper version has a copper/stainless steel top, but is rather because the internals of the HK 3.0 and HK 3.0 LT are different from the internals of the HK 3.0 LC.
