New Waterblock Design Uses Porous Copper
 

Here's an interesting way of making a waterblock. This company has developed a unique waterblock that use porous copper instead of a traditional milled micro-channel design. The company claims this new design is up to ten times more effective cooling than waterblocks currently on the market. Thanks to Edward C. for the linkage! VersarienCu™ is the result of innovative metallurgy research performed at the University of Liverpool's Department of Engineering. It allows the creation of metallic materials with fine, open, interconnected pores which emulate structures that are commonly found in nature. This structural form permits thermal transfer levels that surpass anything that was previously possible.
