Specifications:

Size: 1.75 gram tube
Lower Full load core temperature: 2 to 10 degrees centigrade lower CPU full load core temperature than standard thermal compound of thermal pads. (When measured with a calibrated thermal diode imbedded in the cpu core)
Thermal Conductance:  >4.0 W/mK   (Hot Wire Method Per MIL-C-47113)
Thermal Resistance:  <0.010°C-in²/Watt   (0.001 inch layer)
Extended Temperature Limits: – 40°C to >180°C
Coverage Area: This is enough compound to cover at least 25 to 35 small CPU cores, or 9 to 15 large CPU cores, or 4 to 8 heat plates. At a layer 0.003" thick, one tube will cover approximately 24 square inches.

Description:

For anyone in need of extra thermal compound, Arctic Alumina, by Arctic Silver, is the perfect choice for the multiple system builder.  Arctic Alumina is the  first ceramic-based polysynthetic thermal compound introduced on the market and should out-perform standard non-silicone thermal compound and thermal pads included with most heatsinks and gpu coolers. 

Features:

• Made with micronized aluminum oxide and boron nitride:  Arctic Alumina uses a layered composite of three unique shapes and sizes of ceramic particles to maximize particle-to-particle contact area and thermal transfer. This exclusive combination provides performance exceeding most metal based compounds.
• Controlled triple phase viscosity: Arctic Alumina does not contain any silicone. The suspension fluid is a proprietary mixture of advanced polysynthetic oils that work together to provide three distinctive functional phases. As it comes from the tube, Arctic Alumina's consistency is engineered for easy application in a thin even layer. During the CPU's initial use, the compound thins out to enhance the filling of the microscopic valleys and ensure the best physical contact between the heatsink and the CPU core. Then the compound thickens slightly over the next 50 to 200 hours of use to its final consistency designed for long-term stability.  NOTE: (This should not be confused with conventional phase change pads that are pre-attached to many heatsinks. Those pads melt each time they get hot then re-solidify when they cool. The viscosity changes that Arctic Alumina goes through are much more subtle and ultimately much more effective.)
• Absolute Stability:  Arctic Alumina will not separate, run, migrate, or bleed.
• Electrical Insulator:  Arctic Alumina Compound is a pure electrical insulator, neither electrically conductive nor capacitive.
• Clean up:  Arctic Alumina Compound cleans off easily from CPUs and heatsinks.  In most cases, simply wiping with a dry cloth will remove the compound from the CPU and heatsink.

Important Reminder:
Due to the unique shape and sizes of the ceramic particles in Arctic Alumina, it will take a minimum of 36 hours to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will drop as much as 1C to 2C over this "break-in" period.

Caution:
We do not recommend using Arctic Alumina on the older Intel Xeon processors with large multiple square inch CPU to heatsink interfaces. The huge contact area and large gaps between the processor and the heatsink require a thermal pad or thick mesh-reinforced paste.
