Zalman ZM-STC9 -lämpötahna 9,1 W/m·K 4 g

The Zalman ZM-STC9 thermal compound provides high thermal conductivity of 9.1 W/m·K in a 4 g syringe, ensuring efficient heat transfer between CPUs or other computer chips and their coolers. The grey, non-electrically conductive paste helps reduce operating temperatures and supports stable performance in high-performance systems. Scale markings on the syringe enable accurate visual measurement of the remaining paste, and the rubber cap prevents hardening during storage and reuse.

Advantages

High thermal conductivity improves heat transfer from the chip to the cooler while the non-electrically conductive formulation reduces risk of short circuits. The syringe form factor with scale markings ensures precise application and dosing, and the included rubber cap helps maintain paste usability over time. The compact 4 g volume is suitable for multiple small applications or single CPU installations.

Suitable for

• Applying thermal paste between CPUs and air or liquid coolers
• Thermal interface for GPUs, chipsets and VRM components
• System builds and maintenance where accurate dosing is required

Key specifications

• Thermal conductivity: 9.1 W/m·K
• Weight/volume: 4 g (0.004 kg)
• Colour: Grey
• Form: Syringe with scale markings and rubber cap
• Electrical conductivity: non-conductive

How to use

Clean the CPU and cooler contact surfaces from old thermal paste and dust using isopropyl alcohol and a lint-free cloth. Apply a small pea-sized amount of Zalman ZM-STC9 to the centre of the CPU die, then mount the cooler and tighten according to the manufacturer’s instructions to spread the compound evenly. For larger dies, use a thin line or cross pattern as appropriate. After use, replace the rubber cap to prevent drying of the paste.

Recommendations

Store the syringe in a cool, dry place away from direct sunlight. Do not apply excessive amounts — a thin, even layer provides optimal thermal transfer. Keep out of reach of children and avoid contact with skin and eyes; if contact occurs, rinse thoroughly with water.
