Ten 3.5 g syringes of grey thermal compound in a row

Arctic Silver

Arctic Silver 5 AS5-35G thermal paste 3.5 g x10

SKU CH-XWXC-75ZMM

A pack of ten 3.5 g syringes containing high-density silver thermal compound with 99.9 % pure silver particles and 88 % filler by weight

  • High-density 88 % filler maximises heat transfer
  • 9 % pure silver particles boost conductivity
  • Triple-phase viscosity ensures stable application
  • 10 tubes of 3.5 g each for multiple builds
  • Optimised for modern high-power CPUs and coolers

Arctic Silver 5 3.5 g x10 thermal compound

This pack contains ten individual syringes of Arctic Silver 5 thermal paste, each holding 3.5 grams of compound. It is designed for system builders and technicians who need a reliable supply of premium grease for multiple CPU installations or regular maintenance work. The high-density polysynthetic silver formula is optimised for modern high-power processors and performance heatsinks.

Suited for multi-build workshops and enthusiasts

The lot-of-ten format suits repair shops, integrators and enthusiasts who repeatedly assemble or service computers and want consistent thermal performance across every build. Buyers who only need a single application for a one-off upgrade should look at smaller quantities instead. The compound contains no silicone and uses a polysynthetic oil suspension for stable viscosity.

Sustained load stability and long-term consistency

With over 88 percent thermally conductive filler by weight, including micronized silver and ceramic particles such as zinc oxide, aluminum oxide and boron nitride, the paste maintains its thermal transfer efficiency under continuous high temperatures. The controlled triple-phase viscosity prevents pump-out and separation during extended heavy workloads. The 99.9 percent pure silver content maximises particle-to-particle contact for enduring heat dissipation.

Questions about this item

Do I need a CPU cooler or water-block already installed to use this Arctic Silver 5 paste?

Yes, the compound is applied between the processor heat-spreader and the cooler base, so a compatible heatsink or water-block must be present before you start.

Will the 99.9 % pure silver particles cause any issues with an older aluminium heatsink I plan to keep?

The formula is non-corrosive and electrically non-conductive, so it is safe for direct contact with aluminium, copper or nickel-plated bases found on legacy coolers.

How can I verify the triple-phase viscosity is performing correctly after I mount the cooler?

After the first few thermal cycles the paste reaches its optimal consistency; stable idle and load temperatures that match published expectations for Arctic Silver 5 indicate proper behaviour.
