OCZ's first venture into the world of water cooling was announced today, with the company releasing their HydroFlow KF-MK1 Waterblock for processors. They say the unit is designed for maximum fluid exchange rate, pitching it as a definite "enthusiast" water cooler. They also mention the design forces the cooled water directly onto the die area of the CPU, instead of around it, providing an advantage for reducing heat build up.
It is a waterblock only, designed for integration into just about any pump system. It comes with adjustable barbs, so it should be fairly compatible. This is probably just the first of several OCZ water cooling products planned for release in the future.
