Ceramic thermal compound for CPUs and GPUs

Arctic Silver CMQ2-25G is a 25-gram syringe of ceramic-based thermal compound designed for processor and graphics-card heat spreaders. The polysynthetic suspension fluid carries a tri-linear blend of aluminum oxide, zinc oxide and boron nitride that is electrically non-conductive and non-capacitive. Average particle size is below 0.36 microns for thin, even coverage.

Suited for standard desktop builds

Enthusiasts who want a pure electrical insulator with easy cleanup will appreciate the ceramic formula and innovative dispenser. The tube holds approximately 9.2 cc, enough for roughly 200 square inches at a 0.003-inch layer. Buyers covering very large dies or multiple devices should verify the volume meets their needs.

25-gram volume determines application count

One syringe provides about 9.2 cc of compound, covering approximately 200 square inches when spread to a 0.003-inch thickness. This figure directly decides whether a single tube is sufficient for the intended number of CPU or GPU installations.

Questions about this item

How much area does the 25 g syringe cover at a .003 inch layer?

One 25 g syringe provides roughly 9.2 cc of compound, covering about 200 square inches when spread to a .003 inch thickness.

What is the correct way to apply the paste so the tri-linear ceramic particles spread evenly?

Dispense a small drop onto the centre of the CPU heat-spreader, then mount the cooler straight down; the clamping pressure spreads the compound into a thin, uniform layer without air pockets.

When should the compound be replaced to keep temperatures within the long-term 130 C limit?

Re-apply whenever the cooler is removed or if CPU load temperatures rise noticeably; the ceramic formula does not dry out, but physical disturbance breaks the thermal bond.
