Overclockers Online has posted a new review on the OCZ Tempest cooler

While the CPU cooler does look very nice with the four heatpipes and the shiny fins, its performance was marginally worse than the CNPS-9500. The only real downside to this cooler is the lack of availability. What I did determine was the MSRP, at a whopping $49.99. In my opinion, the premium is a bit high and once this cooler goes global, we'll probably start seeing it at a more reasonable 40 dollar level.
