White 5 g syringe of grey thermal compound with black cap

Prolimatech

Prolimatech PRO-PK2-5G thermal paste 5 g

SKU CH-8N3Q-PM7KE MPN PRO-PK2-5G

A nano-aluminium thermal compound with 10.2 W/m-K conductivity and 0.015 °C-in²/W resistance for easy, stable CPU and GPU heat transfer

  • SpecificationsMaterial Specification: Al 70~88(wt%) ZnO 15~27(wt%) Oil 11~
  • FeaturesExcellent long-term stability Not electrically conductive No
  • High thermal conductivity of 10.2 W/m-? for efficient heat transfer
  • Low thermal impedance of .015 ?-in²/W reduces resistance
  • Non-electrically conductive formula prevents short circuits
  • Non-corrosive composition protects metal surfaces over time
  • Low dry-out characteristic maintains performance long-term

What this thermal compound is and who it suits

Prolimatech PRO-PK2-5G is a nano-aluminium thermal grease supplied in a 5 g syringe. It targets PC builders and technicians who want a high-conductivity paste that spreads easily without a burn-in period.

Check your existing setup before ordering

Ensure the CPU or GPU surface is clean and free of old compound residue. The paste is non-electrically conductive and non-corrosive, so it is safe around exposed components, but verify you have a suitable applicator or spreader for a thin, even layer.

How it fits into a build

The material uses aluminium (70–88 wt%), zinc oxide (15–27 wt%), oil (11–19 wt%) and antioxidant (0.5–2 wt%) to achieve 10.2 W/m-°C conductivity and 0.015 °C-in²/W impedance. Its 250000 Cps viscosity allows a minimal coat that resists dry-out, freeing you from frequent re-application while keeping temperatures stable.

Highlights

  • High thermal conductivity of 10.2 W/m-? for efficient heat transfer
  • Low thermal impedance of .015 ?-in²/W reduces resistance
  • Non-electrically conductive formula prevents short circuits
  • Non-corrosive composition protects metal surfaces over time
  • Low dry-out characteristic maintains performance long-term

Questions about this item

Does the 5 g syringe include an applicator or spreader, or must I buy one separately?

The 5 g syringe is the only item supplied; no applicator or spreader is included, so you will need to provide your own tool for spreading.

The spec sheet lists 70–88 wt% Al and 15–27 wt% ZnO — which composition range should I expect in this tube?

Every tube falls within those published ranges; the exact percentages vary by batch but always stay between 70–88 wt% aluminium and 15–27 wt% zinc oxide.

The headline thermal conductivity is 10.2 W/m-°C — what does that translate to for actual CPU temperatures?

With a thermal impedance of 0.015 °C-in²/W the paste adds very little resistance, so typical CPU temperatures drop a few degrees compared with standard compounds when applied in a thin layer.
