Carbon Microparticle Thermal Compound

Arctic MX-2 2019 Edition is a carbon microparticle thermal paste supplied in a 30g syringe. It delivers 5.6 W/mK thermal conductivity for CPU and GPU heat transfer. The compound is non-capacitive and non-electrically conductive, preventing damage from accidental contact with traces. It suits builders who want a high-stability paste without metal particles.

Overclockers and General Builders

This paste suits overclockers and enthusiasts seeking long-term stability up to 230°C operating temperature. It does not cure, bleed or corrode, making it safe for repeated disassembly. Buyers who require the absolute highest conductivity of liquid metal should look elsewhere. It is also not intended for sub-ambient cooling below -50°C.

Sustained Load Stability

The carbon-based formula does not degrade like metal or silicon compounds over extended periods. High long-term stability maintains low thermal resistance during continuous heavy workloads. Density of 3.69 g/cm3 and viscosity of 2850 poise keep the layer consistent without pump-out. Performance remains steady rather than dropping after initial burn-in.

Questions about this item

What CPU cooler mounting hardware do I need to use this 30 g syringe?

The paste itself requires no special mounting hardware; apply a pea-sized amount to the CPU heat-spreader and secure your existing cooler according to its own instructions.

Will this carbon-based compound remain effective on a ten-year-old GPU heatsink?

Yes, the non-curing formula does not degrade like metal or silicon pastes, so it maintains 5.6 W/mK conductivity on older copper or aluminium bases.

How can I verify the paste is performing correctly after assembly?

Monitor CPU or GPU core temperatures under load; they should drop to expected ranges for your cooler and ambient conditions, confirming the 5.6 W/mK transfer is working.
