@ 2013/03/04In addition to the Dark Knight Frostbourne Edition CPU cooler, XIGMATEK announced the new Xi-3 HDT thermal compound optimized for CPU coolers with heatpipe direct touch (HDT) bases. In such a base, heatpipes of the cooler make direct contact with the CPU, and are nested inside grooves of the base. Gaps between the base and the heat pipes tend to reduce surface area of contact between the cooler and the CPU. By design, HDT bases are less "polished," it helps to have a thermal compound that can seep into to surface irregularities better.
The Xi-3 HDT from XIGMATEK is advertised to have smaller particle size, while making up with higher density. The company didn't specify the composition of the compound, but detailed its characteristics. Its viscosity is rated at 104 Pa·s, specific gravity at 2.5 g/cm³, and an impressive 9.1 W/mK thermal conductivity. As with most performance TIMs on the market, it features an anti-bleed composition, isn't electrically conductive, and has an applied life rated at 10 years. It is sold in 4 g syringes, the company did not reveal pricing.
