Noctua recently released their new NT-H1 thermal compound. This new thermal interface material is designed to give maximum performance while being simple to use. Best of all, it is ready to use immediately and does not require a "burn-in" time like the other manufacturer's products. With a long storage life, long-term stability on the CPU, being non-conductive and being suitable for compressor cooling, this thermal compound seems to have it all.
