[edit] Arctic Silver 5 (AS5)
Arctic Silver 5 is a high-density polysynthetic silver thermal compound, which has become the company's most popular product. The product features a silver purity of over 99%, and it is over 88% thermally conductive material by weight. It does not contain any silicone and contains sub-micrometre zinc oxide, aluminium oxide and boron nitride particles which help maintain long-term stability. This has become the thermal compound of choice by computer enthusiasts and system manufacturers due to its availability and performance levels.
Thermal conductivity of 0.001 in (25 micrometre) layer: >350 kW/(m•K)
Thermal resistance of 0.001 in (25 micrometre) layer: <2.9 mm•K/W
[edit] Arctic Alumina
Arctic Alumina is a ceramics-based polysynthetic thermal compound, which is similar to AS5. However, Arctic Alumina is manufactured using sub-micrometre aluminium oxide.
Thermal conductivity of 0.003 in (25 micrometre) layer: >4.0 kW/(m•K)
Thermal resistance of 0.003 in (25 micrometre) layer: <0.65 mm•K/W
[edit] Céramique
Céramique is a high-density composite of thermally conductive aluminum oxide, boron nitride and zinc oxide sub-micrometre particles. It is not electrically conductive, which makes it a better choice than Arctic Silver when there is a possibility that the thermal compound could come in contact with the pins of an integrated circuit.
Thermal conductivity of 0.001 in (25 micrometre) layer: >200 kW/(m•K)
Thermal resistance of 0.001 in (25 micrometre) layer: <4.5 mm•K/W
