ARCTIC MX-4 Thermal Compound 4g - Premium Thermal Paste
The ARCTIC MX-4 Thermal Compound is a carbon-microparticle thermal paste designed for CPUs and GPUs that need efficient heat dissipation. It suits overclockers, enthusiasts, and anyone replacing dried or degraded thermal compound on their processor. The formula remains unchanged across packaging revisions, prioritising proven performance over cost.
Why this product
Carbon microparticles fill microscopic surface cavities
The paste is engineered to bridge the imperfections between processor and cooler, maximising contact area and thermal transfer efficiency.
Metal-free and electrically non-conductive
No short-circuit risk to the CPU or graphics card, adding a layer of electrical safety during application and use.
Ideal consistency with applicator included
The syringe delivery and balanced viscosity make it accessible even to first-time users; a spatula is supplied for even spreading.
Wide operating range
Performs from −50°C to +150°C, covering typical overclocking and ambient conditions.
Authenticity verification available
Each unit carries a code allowing buyers to confirm they have received a genuine ARCTIC product, not a counterfeit.

- Works with any CPU or GPU that accepts thermal paste in syringe form.
- Safe for use on both air and liquid cooling systems.
- Complies with RoHS and is carbon-neutral certified.
- Best results require even application; uneven spreading or excessive thickness may reduce thermal performance.
Best for
- Overclockers and enthusiasts pushing processor frequency beyond stock settings
- Anyone replacing old, dried thermal paste on an existing build
- First-time builders seeking a beginner-friendly compound with proven performance
- Users who prioritise electrical safety and want no conductive risk
Trade-offs
- Silicone-pad-only systems: Some laptop manufacturers and OEMs use permanently attached thermal pads and do not permit paste replacement.
- Extreme sub-zero cooling: Operating minimum is −50°C; systems using liquid nitrogen or phase-change cooling may require a specialist product.
- One-time disposable tubes: This is a syringe; once opened, it will dry out if not sealed properly between applications.
The surfaces of processor chips and cooler floors are covered with microscopic dents; ARCTIC's MX-4 thermal paste is composed of carbon microparticles which fill these cavities. This leads to extremely high thermal conductivity, ensuring that heat is dissipated quickly and efficiently from the CPU or GPU. With its outstanding performance, the MX-4 is not only an excellent choice for overclockers and enthusiasts, but also for other applications that require thermal transmission. MX-4 proves without a doubt that great performance does not necessarily require a high price.
The MX-4 is metal-free and non-electrical conductive which eliminates any risks of causing short circuit, adding more protection to the CPU and VGA cards.
