PC Apex have a new review up on a cooler named the Vortex XP

The block is easily dissected by removing the 4 machine screws, and separating the Delrin sections with the base plate. The top and mid section are bonded together to reduce chances of leakage. The coolant enters the center barb through the top and middle sections of Delrin onto the baseplate. The baseplate is of a unique design. The baseplate is a forged piece of copper with raised pins in the middle and fins to guide the coolant out of the four corners. A key benefit of this design with the coolant exiting the corners, the possibility of air pockets is reduced. Once the coolant leaves the baseplate it is collected into the Delrin sections. Here an air pocket is more likely form but that's not too critical since it's away from the baseplate.
