With its unique high-density filling of micronized silver and enhanced thermally conductive ceramic particles, Arctic Silver 5 provides a new level of performance and stability. Arctic Silver 5 is the reference premium thermal compound.

Arctic Silver 5 is optimized for a wide range of bond lines between modern high-power CPUs and high performance heatsinks or water-cooling solutions, and for years Arctic Silver 5 has been the preferred choice of many system builders and computer enthusiasts.

Main product features:

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.

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.

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.)

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.

RoHS Compliant.

My 2016 old Asus laptop become faster and quieter after applying the termal paste. I also changed laptop fan.

Needed this urgently to repair my laptop, and after searching in brick & mortar shops and internet, this has been the best possible place. Not too expensive, shipping actually cheaper than the bus I need to take to go to their shop, delivered in one day (despite 2-4 days estimation).
Arctic silver very easy to use, no need to buy anything else (old grease can be perfectly removed with kitchen paper, and product application just needs being careful).
Although there was no tracking information for economic shipping, I was notified at each stage of the process.
Would recommend this thermal paste to anyone needing to fix heating issues on laptop, and would definitely buy again from this website.
