Arctic Silver 5 12g thermal paste

High-density silver thermal compound

Arctic Silver 5 is a high-density polysynthetic silver thermal compound supplied in a 12 gram syringe. It is designed for PC builders and technicians who need reliable heat transfer between a CPU or GPU die and its cooler. The paste uses three unique shapes and sizes of pure silver particles to maximise microscopic contact area. This formulation targets enthusiasts seeking consistent thermal performance without exotic application procedures.

Three particle shapes maximise contact

The single specification that decides suitability is the use of three distinct pure silver particle shapes and sizes. This blend fills microscopic surface imperfections on both the heatsink and the processor core more completely than single-size particle pastes. Greater physical contact area directly improves thermal conductivity and lowers junction temperatures under load. No other thermal conductivity value or comparative metric is provided by the supplier.

Non-separating formula eases application

The compound will not separate, run, migrate or bleed during storage or operation, so the syringe stays consistent and the joint remains stable over time. Application follows the standard pea-sized dot or thin-line method; no special curing cycle is required. The most common mistake is applying too much paste, which can spill onto surrounding components and create a mess without improving temperatures. A thin, even layer is sufficient for optimal results.
