Introducing Arctic Alumina Thermal Compound The first
ceramic-based, polysynthetic thermal compound
for use between modern high-power CPUs and high performance heatsinks or
water-cooling solutions.
The 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.
Thermal conductivity: >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
Lower full load core temperatures:
2 to 10 degrees centigrade lower CPU full
load core temperatures than standard thermal compounds or thermal pads.
When measured with a calibrated thermal diode imbedded in the CPU
core.
Clean
Up :
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.
3.5 gram tubes.
(About 2.2cc) At a layer 0.003" thick, one tube will cover approximately 48
square inches.
14 gram tubes
(About 9cc) At a layer 0.003" thick, one tube will cover approximately 192
square inches.
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.
