neoseeker.com has gotten hold of one of those new Antec JetCool Socket 370 HSF units. let's see if Antec did a better job on the Pentium version of this sink. here's a snip:
"When you take out the sink from the packaging, you'll notice an interesting design as it features aluminum radial folding fins wrapped around a central copper core. The core measures at 29-mm diameter by 34 mm high. The aluminum fins are not bonded to the copper core. The heat transfer from the core to the fins is done by a layer of thermal grease which lies between the base of the aluminum fins and the core."
