ARCTIC COOLING

ARCTIC COOLING MX-4 Thermal Compound Paste 20 Grams

SKU CH-X2BQ-CDP8V

Carbon-based thermal paste for CPU and GPU heat dissipation, non-conductive and durable for at least eight years

  • Carbon micro-particles deliver high thermal conductivity
  • Metal-free formula eliminates short-circuit risk on CPU or GPU
  • Non-corrosive and non-bleeding compound protects sensitive components
  • Consistent performance maintained for at least 8 years
  • Ideal viscosity allows easy application even for beginners

Carbon-Based Thermal Paste

ARCTIC MX-4 is a carbon micro-particle thermal compound designed for CPU and GPU heat transfer. It suits system builders and upgraders who want a non-conductive paste for standard cooler installations. The 20-gram syringe provides enough material for multiple applications.

Non-Capacitive Formula Safety

The paste is metal-free, non-capacitive, non-corrosive and non-bleeding, eliminating short-circuit risks around sensitive components. Its high-viscosity consistency allows controlled spreading without special tools, making it straightforward for first-time applicators. The compound remains stable without drying out or separating over time.

Long-Term Thermal Stability

Rated to last at least 8 years once applied, the compound maintains thermal conductivity without degradation. Efficient heat dissipation supports sustained component stability under load. The carbon-based formula avoids the pump-out effect common with some metal or silicon alternatives.

Questions about this item

What thermal conductivity does the carbon-based MX-4 compound achieve in practice?

The carbon micro-particle formula provides extremely high thermal conductivity, efficiently dissipating heat from CPU or GPU components to maintain system stability under heavy loads.

What physical clearance or mounting does the 20-gram syringe need on a cooler?

The syringe dispenses paste directly onto the CPU or GPU heatspreader; no special mounting hardware is required beyond the cooler's standard retention mechanism.

How is the MX-4 applied, and which step do beginners often get wrong?

Apply a small pea-sized drop to the centre of the heatspreader, then mount the cooler straight down; the common mistake is spreading the paste manually, which can trap air bubbles.
