This is a 3.5 gram tube of Arctic Silver 5 High-Density Silver Thermal Compound. This product was originally developed for use with computer heat sinks to allow more efficient heat transfer and dissipation, but after extensive testing by A Main Hobbies team drivers, it has also proven to be effective for RC applications!
It can be used to drastically lower the operating temperatures of nitro engines, by applying a layer between the engine head and head button. It also helps to aid in the heat transfer between electric motors, or ESC's and their heat sinks. Arctic Silver 5 costs more, and is thicker and more difficult to apply, but provides the best heat transfer capabilities.
Features:
- Contains 99.9% pure silver: Arctic Silver 5 uses three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer.
- High-Density: Arctic Silver 5 contains over 88% thermally Conductive filler by weight. In addition to micronized silver, Arctic Silver 5 also contains sub-micron zinc oxide, aluminum oxide and boron nitride particles. These thermally-enhanced ceramic particles improve the compound's performance and long-term stability.
- Controlled Triple-Phase Viscosity: 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.
- Not Electrically Conductive: Arctic Silver 5 was formulated to conduct heat, not electricity. 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.
- Absolute Stability: Arctic Silver 5 will not separate, run, migrate, or bleed.
