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
syringe, 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.
Compliancy: RoHS
Compliant.

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:
A 3.5 gram syringe 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 syringe will cover approximately 16
square inches.
