FrostyTech posted a Cooljag OAK-H Radial Skived Copper Fin Heatsink Review

The Cooljag OAK-H heatsink is identical to the Cooljag OAK-H2 model in all ways, except for its internally illuminated blue LED fan. Both heatsinks offer a unique approach, largely due to the construction method which utilizes a ring of skived copper fins wrapped around a central copper column. CoolJag's OAK-H heatsink adapts the skived fin technique by turning everything on its side.
