Three gray syringes of thermal paste with measurement markings and rubber caps

Zalman

Zalman ZM-STC7 3-Pack thermal paste 4 g 7.2 W/m·K 220 Pa.s

SKU CH-P10B-GDXDY MPN ZM-STC7

Three 4 g syringes of 7.2 W/m·K thermal compound with measuring graduations and rubber caps for CPU and GPU use

Quantity 3-Pack

  • 3-pack provides 12 g total for multiple builds
  • 2 W/m·K conductivity moves heat efficiently from CPU or GPU
  • 220 Pa.s viscosity spreads evenly without running
  • Syringe graduations show exact amount used each time
  • Rubber cap keeps compound fresh between applications

Zalman STC7 3-Pack Thermal Compound

This three-pack supplies three 4 g syringes of Zalman STC7 thermal paste for CPU and GPU applications. Each syringe delivers 7.2 W/m·K thermal conductivity and 220 Pa·s viscosity. The gray compound uses silicone oil, alumina, aluminum and zinc oxide. It is electrically non-conductive and RoHS compliant.

Best for Standard Coolers and Reuse

The paste suits builders who want a measurable, reusable syringe for typical air or liquid coolers. The graduated barrel lets you see remaining volume. Buyers who need higher conductivity than 7.2 W/m·K or a lower viscosity for ultra-thin bond lines should look at something else.

Simple Syringe Application

The 117.4 x 21.2 x 15 mm syringe fits a rubber cap that prevents drying between uses. Depress the plunger to dispense a controlled amount onto the chip. Common issues are applying too much paste or trapping air bubbles if the surfaces are not clean.

Questions about this item

What cooler or component do I need before applying this 7.2 W/m·K paste?

You need a CPU or GPU with a heatsink or water block ready; the paste fills the microscopic gap between the die and the cooler base.

Can I use this 220 Pa.s compound on an older processor that previously had thicker grease?

Yes, the moderate viscosity spreads easily under mounting pressure and replaces older paste without needing special tools.

How can I confirm the 4 g syringe is dispensing correctly after opening?

The barrel has printed graduations so you can see the grey compound advance and verify the rubber cap keeps it from hardening between uses.
