Introducing Arctic Silver 5 With its unique high-density
filling of micronized silver and enhanced thermally conductive ceramic
particles, Arctic Silver 5 provides a new level of performance and
stability. Now available at Arctic Silver dealers worldwide, Arctic Silver 5
is definitely The New Reference.
Arctic Silver 5 is optimized for use between modern
high-power CPUs and high performance heatsinks or water-cooling solutions.

Features:
Contains 99.9% pure silver:
Arctic Silver 5 uses three unique shapes and sizes of pure silver particles
to maximize particle-to-particle contact area and thermal transfer.
High-Density:
Arctic Silver 5 contains over 88% thermally Conductive filler by weight. In
addition to micronized silver, Arctic Silver 5 also contains sub-micron zinc
oxide, aluminum oxide and boron nitride particles. These thermally-enhanced
ceramic particles improve the compound's performance and long-term
stability.
Controlled Triple-Phase Viscosity:
Arctic Silver 5 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 Silver 5's consistency is engineered for easy application. 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. (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 Silver 5 goes through are much more subtle and ultimately much
more effective.)
Not Electrically Conductive: Arctic Silver 5 was formulated to conduct heat, not
electricity.
(While much safer than electrically conductive silver and copper greases,
Arctic Silver 5 should be kept away from electrical traces, pins, and leads.
While it is not electrically conductive, the compound is very slightly
capacitive and could potentially cause problems if it bridges two
close-proximity electrical paths.)
Absolute Stability: Arctic Silver 5 will not separate, run, migrate, or bleed.

The Comparison at The Tech Zone
(Includes the original Arctic Silver)
Thermal Conductance: >350,000W/m2 °C (0.001 inch layer)
Thermal Resistance: <0.0045°C-in2/Watt (0.001 inch layer)
Average Particle Size: <0.49 microns <0.000020 inch
Extended Temperature Limits: Peak: –50°C to >180°C Long-Term: –50°C to 130°C
Performance:
3 to 12 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.
Coverage Area:
Arctic Silver 5 is sold in 3.5 gram and 12 gram tubes. The 3.5 gram tube
contains enough compound to cover at least 15 to 25 small CPU cores, or 6 to
10 large CPU cores, or 2 to 5 heat plates. At a layer 0.003" thick, the 3.5
gram tube will cover approximately 16 square inches.
Important Reminder:
Due to the unique shape and sizes of the particles in Arctic Silver 5's
conductive matrix, it will take a up to 200 hours and several thermal cycles
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 or with a low speed fan
on the heatsink.) On systems measuring actual internal core temperatures via
the CPU's internal diode, the measured temperature will often drop 2C to 5C
over this "break-in" period. This break-in will occur during the normal use
of the computer as long as the computer is turned off from time to time and
the interface is allowed to cool to room temperature. Once the break-in is
complete, the computer can be left on if desired.
Caution: We do not recommend using Arctic Silver 5 on the older
slot type 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. Arctic Silver 5 can be used on socket type Xeons without a problem.
