New thermal compound beats all the others...
The Swiss cooling solution provider – ARCTIC COOLING has launched a new high performance thermal compound MX-2 for the enthusiast.MX-2 is a high conductive and low resistance compound for components that require the best thermal dissipation. MX-2 is ideally suited for use in CPU, GPU cooling and other applications between power semiconductor components and heat sinks where high thermal conductivity is critical.
Since the MX-2 compound does not contain any metal particles, there are no problems regarding electrical conductivity and capacitance. In contrast to silver and copper compounds, contact with electrical traces, pins, and leads cannot result in any damage.
Curing and bleeding of the compound is not possible. In contrast to metal or silicon pastes, this compound does not show decreasing performance over time, does not need to be reapplied and has a durability of at least 8 years.

“We’re highly impressed for its outstanding performance,” said Patrick Chung, marketing manager of ARCTIC COOLING. “MX-2 outperforms in almost all tests. It’s definitely one of the best non-electric conductive thermal compounds available for all DIY enthusiasts.”
MX-2 will be available by the end of July 2007. The MSRP is USD 7.95 and Euro 5.95 (excl VAT).
