- High thermal transfer backed by 99.9% pure silver particles
- Dense filler load with over 88% conductive material by weight
- Stable long-term performance from sub-micron ceramic particles
- Consistent application via controlled triple-phase viscosity fluid
- 12 g syringe suited for multiple CPU installations
Precision CPU thermal compound
Arctic Silver 5 is a high-density thermal interface material designed for microprocessor-to-heatsink applications. The 12-gram syringe contains 99.9% pure silver particles in three shapes to maximise contact area. It suits enthusiasts building or servicing high-power CPUs with air or water cooling.
Triple-phase viscosity and stability
The proprietary polysynthetic oil suspension eliminates silicone and delivers controlled triple-phase viscosity for consistent spread during installation. Over 88% thermally conductive filler by weight combines micronized silver with sub-micron zinc oxide, aluminum oxide and boron nitride for long-term performance without pump-out or separation.
Simple syringe dispensing method
The 12g syringe allows direct, controlled application onto the CPU heat spreader before mounting the cooler. No separate tools or mixing are required, and the non-electrically-conductive formula reduces risk if excess compound contacts surrounding components. Clean-up uses standard isopropyl alcohol.

Questions about this item
How do I apply the 12 g syringe of Arctic Silver 5 and what step do people usually miss?
Clean both surfaces with isopropyl alcohol, place a small pea-sized dot in the centre of the CPU heat spreader, then mount the heatsink straight down; the step most users skip is letting the compound settle through a few heat cycles before judging temperatures.
Will the 88 % filler content in Arctic Silver 5 dry out or need replacement later?
The polysynthetic oil carrier is designed for long-term stability and does not contain silicone, so the paste resists drying; typical systems run years without re-application unless the cooler is removed.
At what point does the 99.9 % silver particle load hit its thermal limit under sustained load?
The compound itself remains stable well above normal CPU operating temperatures; the practical limit is the cooler's ability to move heat away, not the paste's conductivity.
