Thermal Compound for Arctic Silver 5 (Pack of 2)

Arctic Silver 5 is a premium polysynthetic thermal compound crafted with 99.9% pure silver. It utilizes three distinct shapes and sizes of silver particles to optimize contact area between particles, thereby enhancing thermal transfer efficiency. This design ensures superior performance in dissipating heat from CPUs and other components.

Unlike electrically conductive compounds, Arctic Silver 5 is specifically engineered to conduct heat while being non-electrically conductive. This feature ensures safety around electrical components, although caution is advised to prevent potential capacitive issues near electrical paths.

One of its key benefits is absolute stability; Arctic Silver 5 does not separate, run, migrate, or bleed over time, maintaining consistent performance and reliability.

In terms of thermal efficiency, Arctic Silver 5 demonstrates impressive results, delivering CPU full load core temperatures typically 3 to 12 degrees Celsius lower than standard thermal compounds or thermal pads. This improvement is substantiated through testing with calibrated thermal diodes embedded in CPU cores.

A 3.5 gram tube of Arctic Silver 5 provides extensive coverage, sufficient for approximately 20 to 30 small CPU cores, 6 to 10 large CPU cores, or 2 to 5 heat plates. This ensures versatility in application across various CPU sizes and configurations.

Users should note that Arctic Silver 5 features unique particle shapes and sizes in its conductive matrix. As a result, achieving optimal thermal conduction between particles and maximizing the heatsink-to-CPU interface conductivity may require a break-in period of up to 200 hours and several thermal cycles. During this period, actual internal core temperatures, measured via the CPU's internal diode, may decrease by 2 to 5 degrees Celsius. This break-in process occurs naturally during regular computer use, provided the system is intermittently powered off to allow the interface to cool to room temperature. Once completed, the system can remain operational continuously if desired.

Arctic Silver 5 is ideal for use between CPUs and heatsinks or water-cooling solutions, offering reliability and efficiency in thermal management. It contains no silicone, further ensuring compatibility and longevity in high-performance computing environments.
