FrostyTech has posted a review on the Coolink U2L Heatsink

Built with a body of nickel plated 6063-T5 extruded aluminum and a 2mm thick C1100 copper base, the Coolink U2L is identical in shape to the high-powered U2P varient. Of course in the search for ultimate cooling, manufactures are always looking for the best combination of heatsink and fan, and in this case the U2L is built for quieter cooling. Using an 80mm fan just means that this standard extrusion heatsink works a little better than smaller heatsinks with lower-RPM fans. Sitting above the heatsink fin section is a 25mm thick 80mm 2900RPM fan that produces about 50 dB of noise. This isn't a quiet heatsink in the class of Zalman or Verax, but it is what I think we are going to start calling "lower noise." If Coolink have the equation right, this nickel plated aluminum extrusion heatsink with its' copper base should still be able to offer up some pretty good Athlon cooling.
