Performance claims appear to be an internal thermal resistance of around 0.10C/W for a 10x10mm heat source. Note, that does not include the TIM layer, i.e. what BillA coined as T/W. With the TIM layer (ala BillA style testing) and at 0.6LPM, they are basically saying up around 0.20C/W for a 10x10mm heat source after perusal of their testbed simulation results. This basically puts their block at about on par with the better blocks on the market today.
What is impressive here is their ability to get such good performance at low flow rates, but their block appears to be extremely restrictive. Pushing >2LPM through the block isn't going to be easy and at that point it appears that the block is starting to give diminishing returns.
Overall the results are about where I would expect them to be for a good pure micro-channel implementation.
For me, it's the age-old trade-off. Can get excellent efficiency with micro-channels, but needs a lot of pumping effort. Or can gets substantially less efficiency, but through boosting flow rates can end up about the same anyway. Really it comes down to what flow-rate range (read: pump) that you intend to optimise for. When the heat load really starts to fly though, higher flow rates (>2LPM) tends to be more attractive IMO.
