Arctic Silver 5 Thermal Paste 12g Tube Pack of 5
Five 12 g tubes of 99.9 % silver thermal compound rated for -50 °C to 130 °C long-term operation
- Net content0.25 lb (0.11 kg)
- Continuous-use temperature-50 to 130 °C
- Reduces CPU core temps by 3 to 12 °C under full load
- 9 % pure silver particles maximise thermal transfer
- Over 88 % thermally conductive filler by weight for high density
- Stable from -50 °C to 130 °C long term and peaks to 180 °C
- Non-electrically conductive paste will not separate, run, migrate or bleed
Ideal for high-power CPU builds
This five-pack of Arctic Silver 5 thermal compound suits system builders who need reliable thermal transfer across multiple high-power CPUs. Each 12 gram tube contains 99.9 percent pure silver particles engineered for maximum particle-to-particle contact. The formula is not electrically conductive and offers absolute stability without separation, migration or bleed. It is optimised for modern high-power processors requiring consistent long-term performance.
Coverage per tube and pack
A single 12 gram tube provides enough compound to cover 50 to 55 small CPU cores or 20 to 25 large CPU cores at the recommended layer thickness. The five-pack multiplies this capacity for workshop or multi-system deployments. At a 0.003 inch layer a 3.5 gram syringe covers approximately 16 square inches, giving a reference for smaller applications. Builders needing only a single application or working with non-CPU surfaces may find the total volume excessive.
Thermal limits and conductivity
Long-term operating range spans -50 to 130 Celsius with a peak tolerance exceeding 180 Celsius. Thermal conductance exceeds 350,000 W/m²°C at a 0.001 inch layer and thermal resistance is rated at 180°C. The compound delivers 3 to 12 Celsius lower CPU full-load core temperatures versus standard compounds or pads when measured with a calibrated thermal diode. Over 88 percent thermally conductive filler by weight ensures high-density heat transfer.

Questions about this item
Will the 12 g tube work with an older CPU that has a larger heat spreader?
One 12 g tube covers 20 to 25 large CPU cores at the recommended 0.003 inch layer, so it is sufficient for older, larger heat spreaders.
How can I verify the paste is performing correctly after application?
Expect 3 to 12 °C lower full-load core temperatures versus standard compounds when measured with a calibrated thermal diode in the CPU core.
Does the pack of five include any applicators or cleaning wipes?
The package includes five 12 g tubes of Arctic Silver 5 only; applicators and cleaning wipes must be purchased separately.
