Zalman ZM-STC8 thermal paste 1.5 g 8.3 W/m·K

SKU CH-MATV-XTJ5Z MPN ZM-STC8

High-conductivity 8.3 W/m·K thermal paste in a 1.5 g syringe with graduation marks for precise CPU and GPU application

  • High thermal conductivity of 8.3 W/m·K efficiently transfers heat from CPU or GPU
  • Non-electrically conductive formula protects components from short circuits during application
  • Graduated syringe markings enable precise, repeatable dispensing for multiple uses
  • Optimal viscosity of 350–480 Pa.s spreads evenly without overflow on any chip surface
  • RoHS-compliant, environmentally safe materials ensure hazard-free handling and disposal

Thermal paste for CPU and GPU cooling

Zalman ZM-STC8 is a 1.5 g syringe of gray thermal compound rated at 8.3 W/m·K. The silicone-based formula contains silicone dioxide, aluminum oxide and zinc oxide with no electrical conductivity. Viscosity measures 350 to 480 Pa.s and the operating range spans -40 to 200 °C. A rubber cap prevents the paste from drying out between uses.

Builders who need precise application and re-use

The graduated syringe lets you measure the exact amount required for a CPU or GPU, making it practical for single builds or multiple installations. It suits standard desktop coolers and graphics cards where a non-conductive, medium-viscosity paste is specified. Buyers needing larger volumes for production lines or very low-viscosity compounds for direct-die laptop chips should consider other options.

8.3 W/m·K thermal conductivity

This figure is the primary performance metric supplied for the ZM-STC8 model. It sits between the 7.2 W/m·K and 9.1 W/m·K ratings of the sibling STC7 and STC9 products in the same range. Match this value to the requirement in your cooler or component manual to confirm suitability.

Perguntas sobre este artigo

How often will the 1.5 g syringe of ZM-STC8 need to be replaced?

The syringe holds 1.5 g of compound; typical CPU applications use roughly 0.1 g, so one tube covers many installations and only needs replacing when the rubber cap no longer prevents the paste from hardening.

What is the first limit reached when the paste runs at its maximum 200 °C operating temperature?

The rated operating ceiling is 200 °C; sustained use at that temperature is the thermal limit the material is specified to withstand.

How much heat does the 8.3 W/m·K conductivity move during all-day operation?

At 8.3 W/m·K the compound transfers heat efficiently between the chip and cooler, keeping junction temperatures lower than lower-conductivity pastes under continuous load.
