Artic Silver 5: new thermal compound from Artic Silver

Artic Silver announced its new Artic Silver 5 thermal compound. The number 4 was omitted – I guess just like some streets have 13th building numbers left out. And, as you know, number 4 is considered unlucky in some Asian regions.

Anyway, the new Arctic Silver 5 contains microparticles of silver as well as micronized zinc oxide, aluminum oxide and boron nitride. The filling is made of polysynthetic oils. According to the company, during the CPU´s initial use, the compound thins out to enhance the filling of the microscopic valleys and ensure the best physical contact between the heatsink and the CPU core. Then the compound thickens slightly over the next 50 to 200 hours of use to its final consistency designed for long-term stability.

Here are some Arctic Silver 5 specs:

• Thermal conductivity: >300,000W/m2 °C (0.001 inch layer)
• Thermal resistance: <0.005°C-in2/Watt (0.001 inch layer)
• Average particle size: <0.49 microns <0.000020 inch
• Temperature limits: Peak: –50°C to >180°C Long-Term: –50°C to 130°C

Arctic Silver 5 is shipped in 3.5 g and 12 g tubes for $7.95 and $19.95, respectively.
