We will release Arctic Silver 5 on October 20, 2003.
AS5 is the second product in our new generation of high-density thermal compounds and has several significant advantages over our previous silver compounds.

The polysynthetic suspension fluid is improved.
The new mix of non-silicone synthetic oils is more stable than the mix used in Arctic Silver 3. This further enhances the long-term performance of Arctic Silver 5, especially under high-vibration or other difficult conditions.

The average particle size is smaller. (Less than 0.45 microns <0.000018 inch)
The microscopic thermally conductive particles in Arctic Silver 5 fill the voids between the core and the heatsink more completely to provide improved thermal transfer.

And most important, the performance is much better.
