( 4.8 Average / 483 Ratings )



Arctic Silver


5 High-Density Polysynthetic Silver

Part #



3.5 g


Three unique shapes and sizes of pure silver particles to maximize particle-to-particle contact area and thermal transfer.
Contains over 88% thermally conductive filler by weight.These thermally-enhanced ceramic particles improve the compound's performance and long-term stability
Ensure the best physical contact between the heatsink and the CPU core.
Will not separate, run, migrate, or bleed.


Average Particle Size: <0.49 micron <0.000020 inch
Extended Temperature Limits: Peak: -50 Degrees C to >180 Degrees C
Long-Term: -50 Degrees C to 130 Degrees 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: 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.

I heard good things about this thermal compound, and it's pretty good for the money, though it does have a lengthy break-in time.

Great quality, great price. If you want better cooling performance, don't hesitate taking the included thermal compound off and replacing it with this. It bringed the temperature down by 3°C.
