Spire 5F271B1L3 Copper Core Heatsink Review

The Spire 5F271B1L3 FalconRock II is large socket A heatsink that slims down to a mounting profile of just 60x60mm. The curved shape of the cooler allows a 80mm fan to be attached to the fins so noise levels are kept under control without sacrificing thermals. For some strange reason the 80mm fan Spire have packaged with the FalconRock II is made with a cast-aluminum frame. This isn't altogether shocking since many fans are made with aluminum frames for industrial applications, but it is unique for processor cooling.

No explanation is given by Spire for this rather interesting fan-choice, but I think it is safe to say that aluminum-framed fan has essentially no effect on the overall thermal capabilities of the 5F271B1L3 heatsink.

What will have an effect on how thermally efficient the FalconRock II proves to be is the small copper disc inserted into the base. If done properly, the copper will ultimately increase the surface area of the heat source enticing quicker transmission to the outer fins more effectively.

Every once in a while we catch glimpse of a new technology being used for the sake of cooling. The Spire 5F271B1L3 is a pretty standard extrusion except for the design and implementation of the base area.

Rather than use a flat surface, the base angles up towards the center - providing more thickness and girth for the spreading of heat energy to the outer fins. The sides of the base have been cut away to yield that curved edge which also makes this rather large heatsink easily mountable on cramped Socket A motherboards where space around the processor is scarce.
