Alumina Compound uses a layered composite of aluminum oxide
and boron nitride to provide performance exceeding most metal
Arctic Alumina Compound is a pure electrical insulator, neither
electrically conductive nor capacitive.
Arctic Alumina Compound does not contain any silicone. The
suspension fluid is a proprietary combination of advanced
Arctic Alumina is engineered for controlled triple phase
The complex polysynthetic oils work together to provide three
distinctive functional phases. As it comes from the tube,
Arctic Alumina's consistency is optimized for easy application
in a thin, even layer. During the CPU's initial use, the Arctic
Alumina compound thins out to enhance the filling of the microscopic
valleys and insure the best physical contact between the heatsink
and CPU core. Then the compound thickens slightly over the
next 20 to 100 hours of use to its final consistency designed
for long-term stability.
(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.)
Arctic Alumina Compound cleans off easily from CPUs and heatsinks.
In most cases, simply wiping with a dry cloth will easily
remove the compound from the CPU and heatsink.
Arctic Alumina is sold in:
1.75 gram tubes.
(A bit more than 1cc) 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.
14 gram tubes
(About 9cc) At a layer 0.003" thick, one tube will cover
approximately 192 square inches.
