Thermal Compound PRIMECOOLER PC-C125S HQ Silver 25 g paste for CPU/GPU cooling

PRIMECOOLER PC-C125S HQ Silver is a 25 g thermal compound supplied in a syringe for improving heat transfer between CPUs/GPUs and their coolers. The silver-filled paste fills microscopic gaps on mating surfaces to increase thermal conductivity and contribute to stable cooling performance during regular use and maintenance.

Advantages

The silver-based thermal paste offers thermal conductivity greater than 7.5 W/m·K and a low thermal resistance down to 0.06 °C. Supplied in a 25 g syringe, it is convenient for multiple applications and replacements and provides consistent application and coverage on processor and cooler contact surfaces.

Suitable for

• CPU and GPU cooling in desktop PCs and workstations
• Reapplying or replacing thermal interface material during maintenance
• Custom cooling solutions and aftermarket heatsink installations

How to use

Clean both the processor and heatsink contact surfaces from old thermal material and dust using isopropyl alcohol and a lint-free cloth. Apply a small, even amount of the PRIMECOOLER PC-C125S paste to the centre of the CPU die or on the cooler contact area, then mount the cooler according to the manufacturer's instructions to spread the paste evenly. Reassemble the system and monitor temperatures after the first run to ensure proper contact and cooling performance.

Usage recommendations

Use a minimal but sufficient amount to avoid excess squeeze-out; reapply paste when replacing or removing the cooler, and store the syringe capped in a cool, dry place.
