PCBuilder Micrometre 8.5 W/mK Thermal Paste 2g

Overclockers and system builders know that a few degrees can make the difference between a stable high-performance rig and thermal throttling. The PCBuilder Micrometre thermal paste is engineered for those who demand efficient heat transfer from CPU, GPU, or chipset to cooler. With a thermal conductivity of 8.5 W/mK and a non-curing, non-corrosive formula, it fills microscopic imperfections on mating surfaces to reduce thermal impedance to less than 0.05 °C-cm²/W. The 2g syringe provides enough compound for multiple applications, and the included spreader tool ensures an even, thin layer every time.

Why choose it

This paste balances high thermal performance with ease of application. Its viscosity is tuned for spreading without excessive force, yet it stays in place during cooler installation. The non-electrically conductive nature eliminates the risk of short circuits if excess paste contacts nearby components. The wide operating temperature range ensures reliability in both sub-zero ambient cooling and high-load scenarios.

Ideal use cases

• High-performance desktop CPUs and GPUs
• Laptop CPU/GPU re-pasting
• Chipset and VRM cooling
• Console repairs and upgrades
• Industrial and embedded systems

Good to know

The 2g syringe contains enough paste for approximately 5-10 applications depending on die size. Store in a cool, dry place and keep the cap tightly sealed between uses. The spreader tool helps achieve a uniform layer, but the pea-sized dot method also works well. Clean old paste with isopropyl alcohol before applying fresh compound for optimal results.
