Excellent high thermal conductivity. White paste. Has
UL flammability rating of V-1 using the UL 94 test. Has
outstanding adhesion and electrical properties. Resistant
to heat, cold, moisture, UV, ozone and chemicals. When
cured, retains elastomeric properties throughout the operating
temparature range of -55°C to 200°C (-67°F

SILVER 5 THERMAL COMPOUND 3g
Silver Thermal Compound
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.
