Thermal paste for CPU and GPU cooling

Prolimatech PRO-PK1-1.5G is a 1.5 g syringe of thermal compound built for desktop processors and graphics cards. The mixture uses aluminium and zinc oxide in an oil carrier with an antioxidant. It is non-electrically conductive and non-corrosive, making it safe for direct-die and heat-spreader applications.

Replaces dried or stock paste when temperatures

Swapping aged compound for this formula cuts thermal impedance to 0.017 degrees -in2/W and raises conductivity to 10.2 W/m - degrees. The jump is worth it when a cooler runs louder than expected or when a fresh build needs reliable contact without a burn-in period.

Check syringe volume and mounting pressure before

The 1.5 g fill covers several standard CPU installations but may fall short for large cold plates or multiple GPUs. Ensure the cooler applies even pressure so the 310000 Cps viscosity spreads thin without gaps, and confirm the surface is clean of old residue.

Questions about this item

How much thermal paste does the 1.5 g syringe provide for a typical CPU application?

The 1.5 g syringe contains enough compound for multiple CPU applications, with the manufacturer noting that less product is needed per use.

Does the compound require a curing period before it reaches full thermal conductivity of 10.2 W/m-K?

No burn-in time is required; the paste delivers its rated 10.2 W/m-K thermal conductivity immediately after application.

Will the aluminium and zinc oxide particles in the compound cause electrical shorts if they bridge adjacent pins?

The compound is not electrically conductive, so the Al and ZnO filler particles will not create short circuits between pins.
