Arctic Silver 5 3.5g thermal compound

Arctic Silver 5 is a high-density polysynthetic silver thermal compound supplied in a 3.5 gram tube. It is intended for PC builders and technicians who need reliable heat transfer between a CPU or GPU die and its cooler. The paste contains 99.9% pure silver and over 88% thermally conductive filler by weight.

Capacity covers 15 to 25 small CPU cores

The 3.5 gram tube provides enough material for at least 15 to 25 small CPU cores, 6 to 10 large CPU cores, or 2 to 5 heat plates. At a 0.003 inch layer thickness it covers approximately 16 square inches. Users with many large dies or frequent reapplications may need additional tubes.

Triple-phase viscosity and temperature limits

Controlled triple-phase viscosity prevents separation, running, migration or bleeding during long-term use. The compound remains stable from -50°C to above 180°C peak, with a long-term operating range of 50°C to 130°C. It is not electrically conductive, avoiding short-circuit risk if excess spreads onto surrounding components.

Questions about this item

Will this compound work on the older CPU I plan to keep without any risk to the socket?

The compound is not electrically conductive, so it will not cause shorts if it contacts pins or the socket. It also remains stable between -50°C and 180°C, covering the thermal range of legacy processors.

How can I verify the paste is performing correctly after I apply it?

The manufacturer states typical full-load core temperatures drop 3 to 12 degrees Celsius versus standard compounds when measured with a calibrated thermal diode embedded in the CPU core.

What does the 3.5g tube include and is any tool or cleaner supplied?

The tube holds 3.5 grams of compound — enough for 15 to 25 small CPU cores, 6 to 10 large cores, or 2 to 5 heat plates at a 0.003 inch layer. No applicator or cleaning solution is included.
