The OCZ Tempest heatsink weighs in at 580 grams, and is built upon a design that relies heavily on copper components. The design is a fairly predictable mix of copper, heatpipes and a big low RPM fan, so it will be interesting to see how OCZ's product fairs against the strong lineup of socket AM2/939 AMD Athlon64 heatsinks on the market right now. Below the OCZ Tempest's 95mm diameter blue LED illuminated fan is an array of nickel plated copper fins which are joined to the base of the heatsink by four 6mm heatpipes. If you have a upgrade plans penciled in for the near future, the Tempest can certainly accommodate all CPUs.
