Arctic Silver 5 uses three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer. It also contains micron-ized zinc oxide, aluminum oxide and boron nitride in addition to the silver. These thermally-enhanced ceramic particles improve the compound's performance and long-term stability.

Arctic Silver 5 does not contain any silicone. The suspension fluid is a proprietary mixture of advanced polysynthetic oils that work together to provide three distinctive functional phases. As it comes from the tube, Arctic Silver 5's consistency is engineered for easy application. 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.

Features:

• Arctic Silver 5 will not separate, run, migrate, or bleed
• Easy Application along with long-term stability
• Formulated to conduct heat, not electricity
• 3.5 gram tube contains enough compound to cover at least 15 to 25 small CPU cores, or 6 to 10 large CPU cores, or 2 to 5 heat plates. At a layer 0.003\" thick, the 3.5 gram tube will cover approximately 16 square inches
• 3 to 12 degrees centigrade lower CPU full load core temperatures than standard thermal compounds or thermal pads. When measured with a calibrated thermal diode imbedded in the CPU core.

Specifications:

• Thermal Conductance: =>30 x104 W/m2.°C (0.001 inch layer)
• Thermal Resisitance: =<0.005°C-in2/Watt (0.001 inch layer)
• Average Particle Size: =<0.49 microns <0.000020 inch
• Peak Temperature Limits: –50°C to >180°C
• Long Term Temperature Limits: –50°C to 130°C

Note: While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.
