Spire 5R266B1H3 Copper Core Heatsink Review

Built with the AMD Athlon 1.4GHz and AMD AthlonXP 2200+ in mind, the Spire 5R266B1H3 EagleStream is a standard 6063 T5 aluminum extrusion with a special 30mm diameter copper core insert. The copper insert makes direct contact with the processors core to help spread out the heat to the remaining aluminum body. Additionally, we can see that this heatsink uses a nice three-prong clip. Socket A heatsinks can often exert enough force over time to snap of the little plastic tabs on the socket. With the clip using all three the chances of this happening are pretty remote. Spire / Speeze and Fanner are all names that have been used independently for the products from this company, Fanner Tech Co. To keep things simple, we have listed this heatsink under the name of "Spire." The packaging says Speeze, but the two are the same company anyway.
