Home Made Diamond Thermal Paste Put To The Test

@ 2009/09/07
The adding of diamonds did improve the performance of the of both the silicone oil and DC Thermal Fluid, but it did not improve them by that much. A few things might be effecting this. The mixtures might not be mixed well enough leaving clumps of diamonds. The problem with increased mixing is that it introduces more sub mm and um sized bubble. And since we cannot remove the smallest of these bubbles, increased mixing might lead to worse performance. Also, the amount of diamonds may have been too small. The problem with adding more is the viscosity of the slurry increases. Since slurries behave like solids and liquids, this may effect the mixtures ability to thin once the heatsink is added. Playing with juts these two variables adds two orders of magnitude to the complexity of the problem and that is why I did not explore them further. However, it is safe to conclude that you will not stumble upon the optimal mixture as inventgeek seems to suggest they did.

The best performing TIM turned out to be the DC Thermal Fluid with diamonds. It preformed slightly better than AS5. One may wonder why I didn't add diamonds to AS5. That is because I'm not made of money. It may have also decreased performance if I added too much or if the mixing added too many bubbles. But in the end, performance could not be improved by that much anyways.
