FrostyTech has posted a JMC 401100 Phoenix 70 Radial Fin P4 Heatsink review

It's always kind of interesting to receive a prototype heatsink for testing, especially when it comes with a full set of blueprints explaining how the whole thing is put together. The Phoenix 70 (model No. 401100) is a new heatsink from JMC Products that might remind more than a few of you of the old Arcticooler from Agilent Technologies. That heatsink has been wiped from the corporate slate, but its memory lives on in the form of JMC Phoenix 70 which even has a little Arcticooler logo on it. What makes the JMC Phoenix 70 so interesting is that the heatsink fins are cut from a single block of aluminum in a radial 360 degree pattern. The 67mm diameter fan impeller is mounted inside a ring of thin fins and when the heatsink is in operation two separate air flow streams are created. The first stream consists of air as it is sucked into the fan through fins at the top of the heatsink. The second stream is created as exhaust air is pushed out through the fins at the base of the heatsink.
