Ok, I got it and built it.. So here's my comments about the components:
ASUS GTX 570 DirectCU II
This thing is not quiet

I don't know how anyone could say it was quiet, I'd hate to hear whatever it was they were comparing it to.
The cooler is great, keeps it very cool. But the fans are terrible. 1170-3420RPM, it seems, and even at lowest speed they are the most noticeable sound from the PC. I don't know why anyone would need almost 3500RPM anyway, as the cooler works fine at much lower levels. So, ASUS, why did you put such silly fans on an otherwise good card?
ASUS P8P67 Pro
This motherboard isn't as nice for fan control as I had been hoping. There's 4 fan headers, but as far as I can tell, one isn't controllable at all, and two of the others have their speeds linked. So really there's only two controllable speeds

Nice cooler, and the fan included isn't too bad either. But. Doesn't work well at all with the P8P67! I really don't know why Scan were offering them together in bundles. The only way to install it is a workaround:
The cooler is attached to the motherboard with two metal brackets. The brackets have screws that can slide between 3 positions, A B and C, and you are meant to choose the right position depending on the CPU socket you want to use it with. For LGA1155/6, this is B. The brackets are connected to the cooler itself with screws that can go through one hole for A and B positions, and another for C (from memory..). The problem is that in B position, the "arm" on the bracket with the extra hole positions sticks out quite a way. Installing it like this on the P8P67 Pro is impossible. If you try to mount it with the cooler horizontal, the "arm" is blocked by one motherboard heatsink. Vertically, the arm is blocked by the other heatsink. What I had to do was use one bracket connected to the cooler with the A/B hole, and the other with the C hole, and have the sliding screws sort of mid-way and not in any of the three positions. With it like this, I could mount it either horizontally or vertically, but horizontally, the heatsink projected over the RAM sockets, so I went with vertically.
All this could have been avoided, I believe, if they had just included two mirror-image brackets, rather than two identical ones. Or, two brackets specific to this mounting-hole-distance, without the sliding screws. But oh well.
