FrostyTech has posted a Spire BFA07B2 Copper Core Heatsink review

The Spire BFA07B2 is an AMD recommended heatsink according to the manufacturers website. And from the outset that may seem a little confusing as the BFA07B2 MicroFlow II is basically just a simple aluminum extrusion. Flipping over the heatsink yields a soft copper core inserted into the base which should help improve the thermal efficiency of this small cooler. Based on an older design which did not feature a copper insert, the BFA07B2 can almost be considered a second generation heatsink. The core construction remains the same, but in addition to the copper insert the clip has been modified, and even the fins are shaped differently. Spire have even done something a little different with the power cable coming from the fan. Instead of having three bare wires, they have wrapped the power cord with a white mesh sleeve. Case clutter really isn't the issue, but presenting a nice tidy image can't hurt.
