How is this different than the numerous thermally conductive filled epoxies? They come in both electrically insulating and electrically conducting varieties with many different fillers. Regardless, I wouldn't use glue to connect a CPU to a heat spreader in a conventional PC. Thermal expansion mismatch can cause issues when using glue and this also prevents re-use of the CPU or heatsink. I frequently use thermally conductive epoxies at work to attach temperature sensors, these are relatively inexpensive so re-use isn't an issue and its important that they don't fall out and often clamping isn't practical. I also often use thermally conductive glue to attach thermoelectric (peltier) modules where clamping is difficult. Here is the article in Advanced Materials and processes: http://mio.asminternational.org/amp/201601/#24 http://mio.asminternational.org/amp/201601/#24 and here is the article in Scientific Reports http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4653628/ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4653628/ Looks like they use metallic nanoparticles grown on the surface that alloy with different metallic nanoparticles on the opposite surface to stick together.
