The forked-fins of this extruded aluminum heatsink make it pretty evolutionary for its class; especially considering Intel's recently announced bifurcated reference heatsink for the socket 775 Tejas-FMB1. The 'sun' shape of the Thermal Integration TI-RV104N, with copper in the center surrounded by aluminum, is a hint of what you can expect when computers make the switch to socket 775 - only the heatsink will be about 80mm in diameter. With a diameter that large, it leads me to wonder if plans aren't also in the works to come out with a Socket 754 Athlon64 version based on the TI-RV104N. In any case, it is too early for that so let's get started and see how the Thermal Integration TI-RV104N performs thermally, and acoustically!
