I don't get it, I thought the point of water cooling was to get rid of fans (and overclock, of course)?

Well the purpose of these coolers (between this and the cosair coolers) is to get the perks of water cooling temp wise, but without actually having to go out and spend a fortune on blocks, rads, tubing etc.
Although there are fans, its meant for a simpler solution.

Awesome price.

You still need fans to push hot air away from the radiators and bring it cool air.
I'm not sure how this compares to higher end air coolers, but this would be a nice GPU cooler if someone needs it and its decently priced.

How do you get this to work in a GPU? Custom mount for the block?

yes you need an "adapter bracket" they're only $15, so it's not something crazy.

The other advantage these simple closed loop systems have, is you can use them on certain motherboards that have terrible layouts with the ram or pci slots very close to the cpu socket. Otherwise with many of the air cooler they block something like your ram slots which is kind of inconvenient you know, deciding on using any ram at all or a cpu cooler lol.

Watercooling was never about getting rid of fans, it was to allow larger, slower spinning (quieter) fans and get more cooling from them by pushing the heat directly out of the case.
Watercooling got started back in the days when coolers used 60 and 80mm fans, which are noisy. By using water you could pump the water out to a larger heatsink (radiator) and attach a larger, slower spinning fan, ergo, more cooling capability with less noise. A side benefit was that it also allowed you to blow the heat out of the case directly, instead of just recirculating it inside and trying to push it out with lots of other fans.
Today we have heat pipes and have 120mm fans attached to heatsinks, and better vented cases, however the heat can still circulate inside the case. Water lets you dump it right out the side of the case.

We've always been able to sleeve a large fan onto a heatsink designed for a smaller one, but such devices are limited in their efficacy due to the large amount of losses incurred, coupled with the impracticality of mounting such a device in a normal computer case. A watercooler's tube acts as a heat pipe. Since you can direct it wherever you want, you can transmit the heat from a chip to anywhere that's practical (out of the case is a good option). The radiators for water coolers also have large areas, allowing for a larger (or more) fans and thus a better CFM : RPM (and also cooling : noise) ratio.
Or you can do what I eventually want to do and take my eight 160MM fans with steel housings, get some teflon sheeting, and build a "wind tunnel". Each fan can do at least 250-300CFM, and I wont' have that many losses. With teflon, the boundary layer will be really thin, significantly decreasing turbulence (and acting more as an "ideal" windtunnel), meaning the velocity and diameter will have a nearly ideal proportion. The static pressure will be high, and I'll be able to dissipate a ton of heat. The only downside is the 22.2W/fan (177 total) and the noise (at least 70 dB/fan).
Another option is to just get a car radiator (or intercooler) and attach an array of fans to it, but it's less, y'know, excessive (still excessive, though).

I thought decreased turbulence produced poor cooling because the air forms a static warm layer which cooler air simply flows over instead of "blowing it away"
I remember this from the documents on the sandia cooler...

You need less turbulence before the air hits the cooler. No matter what happens beforehand, the flow will certainly no longer be laminar once it starts to pass through the heatsink. You're right though: It's all about the boundary layer.
