garrison,
I compared the Golden Orb, Chrome Orb and Alpha FCPGA-35t on a P3-700 overclocked to 933 MHz @ 133 FSB.
There is some appeal for the Chrome Orb. It cools just a hair better than the Golden using the same space and cools as well as the Alpha using much less space. The Alpha cools 10F better than the Golden Orb at full load, and 3F better at idle, but it blocks off two of the four memory slots in the Asus P3B-F. The Chrome Orb with Arctic Silver cools as well as the Alpha and blocks only one memory slot. The Golden Orb is good enough for the overclocked P3-933 with absolutely no stability problem. Mechanically speaking, it is the most stable of the three.
There is one warning about using the Chrome Orb on Coppermine CPU. The Chrome Orb comes with the Chomerics T-725 phase change thermal interface material when shipped from Thermaltake. The Chomerics T-725 is designed for the Duron/Thunderbird which generate a lot of heat. It will not become effective until high heat is applied to it. Since the Coppermine runs a lot cooler than AMD CPU's, it is not hot enough to cause the phase change. The Chomerics T-725 is a very poor thermal interface for the Intel CPU. Scrap the Chomerics T-725 (relatively thick light brown sticky stuff) off the heat sink and clean it with paint thinner before using it on coppermine.
