Five gray syringes with measurement markings and rubber caps

Zalman

Zalman ZM-STC7 thermal paste 4 g 7.2 W/m·K 220 Pa.s 5-pack

SKU CH-KYJG-QV10Y MPN ZM-STC7

Five-pack of 4 g syringes with 7.2 W/m·K conductivity and 220 Pa.s viscosity for CPU and GPU cooling

Quantity 5-Pack

  • High 7.2 W/m·K conductivity moves heat fast from CPU or GPU
  • Non-conductive formula protects components from short circuits
  • 220 Pa.s viscosity spreads evenly without running
  • Syringe with graduations lets you measure exact amount
  • Rubber cap keeps paste fresh for repeated use

Five-pack for multiple builds

The Zalman ZM-STC7 thermal paste comes in a five-pack of 4 g syringes, giving enough compound for several CPU or GPU installations. It is suited for system builders, upgraders and anyone who maintains more than one machine. Buyers who need only a single application may find the multi-pack excessive.

Consistent conductivity under sustained load

Thermal conductivity is rated at 7.2 W/m·K with a viscosity of 220 Pa.s and density of 2.6 g/cm³. The silicone-oil base with alumina, aluminum and zinc-oxide fillers remains non-electrically conductive and RoHS compliant, so heat transfer stays stable during extended gaming or compute sessions without risk of shorting nearby components.

Syringe with graduations and rubber cap

Each 117.4 x 21.2 x 15 mm syringe has printed graduations for visual measurement and a rubber cap that prevents the paste from hardening between uses. The medium viscosity spreads easily under cooler pressure; the only common issue is applying too much compound, which can be avoided by following the scale markings.

  • Non-conductive formula protects components from short circuits
  • 220 Pa.s viscosity spreads evenly without running
  • Syringe with graduations lets you measure exact amount

Questions about this item

Does the 220 Pa.s viscosity paste dry out or pump out after the CPU runs all day?

The 220 Pa.s viscosity and rubber cap on the 117.4 mm syringe resist drying and pump-out during continuous operation.

What must I already have to apply this 4 g syringe of gray compound?

A clean CPU or GPU surface, isopropyl alcohol, and a lint-free cloth are needed before dispensing from the graduated syringe.

Will the 7.2 W/m·K conductivity work with an older aluminium heatsink I want to keep?

Yes, the silicone-oil, alumina, aluminum and zinc-oxide formula is non-conductive and safe for legacy aluminium coolers.
