Thermal compound with 6.5 W/m-K conductivity spreads easily, needs no burn-in, and is non-conductive
This non-silicone thermal compound delivers a thermal conductivity of 6.5 W/m-K and a thermal impedance of 0.009 K-in2/W. It spreads easily and evenly without requiring special storage conditions. The gray grease is non-corrosive, non-electrically conductive, and requires no burn-in time. It offers excellent long-term stability with low dry-out characteristics.
The 2.5 g syringe suits standard desktop processor applications and routine maintenance. Users requiring electrically conductive paste or larger volumes for multiple builds should look elsewhere. The compound is not intended for sub-ambient cooling scenarios or extreme overclocking setups demanding specialised liquid-metal interfaces. It also lacks specific certifications for industrial or server-grade validation.
A typical CPU installation uses a pea-sized drop, so the syringe provides enough material for multiple reseats or a small batch of builds. Viscosity below 600,000 CPS ensures consistent spreading without excessive force. The dielectric strength of 0.9 KV/mm confirms electrical isolation for safe use around exposed components. Specific gravity of 2.5 g/cm3 indicates a dense, stable paste that resists pump-out over time.

You need a compatible CPU cooler or water block already installed on the motherboard; the paste itself only fills the microscopic gaps between the cooler base and the processor heat spreader.
Yes — clean the old compound thoroughly with isopropyl alcohol, then apply the TP-1; its low 0.009 K-in²/W impedance and non-corrosive formula work safely on legacy CPUs.
Monitor CPU core temperatures under load; a drop of several degrees versus the previous paste indicates the 6.5 W/m-K conductivity and low dry-out are working as intended.
