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.
- 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.
- 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.
