Qui un riassunto delle prove di sto tipo,solo che pensavo parlasse delle paste metalliche in generale invece qui trattasi proprio di metallo liquido,cito "The paste is a Gallium Indium alloy with traces of precious metals"
Oltretutto ne parla bene poiche' sostiene che guadagna 3 4 gradi in idle (solo con la pasta azz...) pero'...
After 3 weeks on the second test platform it is time for the final results.
I am impressed by the effectiveness of the liquid metal. It consistently outperformed AS5 by a minimum of 3 K under load on the Venice platform. On the Atlhon XP the results were even better, I assume this is due to the bigger surface area. I might test it with a IHS CPU one day, but the nature of this material makes it an enthusiast only choice imho, many of which remove the IHS. The performance did not degrade or enhance over the period of 3 weeks, which indicates despite it's liquid nature it will stay in place over long period of time even in vertical position..
There are some bad news however. While checking the heatsink and control surface after cleaning, I did notice some hard to remove traces of the liquid metal. After trying to clean them of with isopropyl alcohol, aceton and even nitro paint thinner the traces remained. It seems some of the Gallium/indium bonds with the copper or its' impurities permanently. The only way I was able to remove it, was by lapping the surfaces. The CPU die also has several traces of the liquid metal, I don't know if these are the result of my mounting methods or a bonding effect with the protective layers of the CPU die, the uneven distribution lets me think it's the former. The consistency of the temperature measurements suggest that these traces do not affect performance greatly. My limited metallurgy knowledge lets me speculate this "cold alloying" only creates a thin outer layer that stops the process from continuing further into the material (if you had any metallurgic education, please share your knowledge).
