Arctis Silver 5 Specifications:
(Note: Information from Arctic Silver website)
|
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. |
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. |
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.) |
And the Numbers:
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.
What does that all mean?
