By now I’m sure most if not all of you know what arctic Silver II is and why it’s the best. arctic Silver, Inc which all of us overclockers have come to know and love. They have come out with the newest revision of their silver thermal compound, arctic Silver 3.
Arctic Silver 3 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 3’s consistency is engineered for easy application in a thin even layer.
During the CPU’s initial use, the compound thins out to enhance the filling of the microscopic valleys and insure 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.
Arctic Silver 3 uses three unique shapes and sizes pure silver parcticles to maximize parcticle-to-parcticle contact area and thermal transfer. This exclusive combination gives the compound a distinctive silver-green color as each type of parcticle reflects light differently. Arctic Silver 3 also contains a small percentage of specially engineered micronized boron nitride. The thermally-enhanced boron nitride ceramic parcticles improve the compound’s flow characteristics and long-term stability.
You can tell from the picture below comparing the look of arctic Silver II and arctic Silver 3 that 3 is a little darker in color. Also the feel of 3 compared to II is that 3 during application goes where you want it easier.
