Results

Fascinating. Ice2 has the lowest average CPU temp, but ties Blue2 for the highest CPU peak temp. The Silver samples had almost identical results. The experimental sample ties with Ice2 for the lowest average case temp. It appears that with the motherboard out of the case, cooling hits a "brick wall." No standard thermal solution, as it would seem, can lower the heat below this threshold. Funny, even in a case, this P4 runs much cooler than my old P3 700 overclocked to 933 MHz.

Conclusion

Although Blue2 is very good, viewing the numbers, it's pretty easy to pick the winner--Ice2. But Ice2 only "wins" by a nose. With the lowest average CPU and case temps, this is a top notch grease that costs pennies per application and will last for years. Both the Silver XTC and experimental samples show great promise, but as they are not in production form (and an unknown pricing scheme), it would be premature to give them a nod just yet.
