ARCTIC MX-4 45g Thermal Compound - Carbon Based Paste
The ARCTIC MX-4 45g Thermal Compound is a carbon-based thermal paste designed to fill microscopic cavities between processors and coolers, enabling efficient heat dissipation. It suits overclockers, enthusiasts and anyone building or servicing systems that demand reliable thermal performance without electrical conductivity. The non-drying formula and resealable packaging maintain performance over years of use.
Why this product
Thermal conductivity of 8.5 W/mK
Microparticles fill surface cavities to transfer heat quickly from CPU or GPU to cooler, keeping temperatures stable under sustained loads.
Non-drying, non-bleeding formula
Maintains consistent performance for up to 8 years without separation or hardening, even under thermal cycling.
Metal-free and non-conductive
Safe around sensitive components; no risk of short circuits or electrical damage if paste contacts circuit board traces.
Resealable, recyclable packaging
Prevents the paste from drying out between uses and reduces environmental footprint compared to conventional packaging.

- CPU and GPU cooling across Intel and AMD platforms, from older chips to current-generation processors.
- Compatible with all common cooler types: air towers, all-in-one liquid coolers, and custom water loops.
- Not suitable for systems requiring liquid metal paste; this is a traditional compound and will not perform the same role as conductive metal alternatives.
Best for
- Overclockers and enthusiasts pushing CPU and GPU frequencies higher than stock
- Long-term stability builds where paste longevity matters more than peak-minute performance
- Builders who need a safe, non-conductive option near exposed circuit board traces
- Anyone reapplying thermal paste on an existing system without risk of electrical shorting
Trade-offs
- Users seeking absolute maximum thermal performance; liquid metal pastes conduct heat slightly more efficiently but require more careful application.
- Extreme overclocking scenarios where every degree and millisecond counts; specialist compounds may edge ahead in laboratory conditions.
Depending on personal preference and area of application, a thinner or thicker thermal compound may be preferred. Excellent non-drying and non-bleeding properties ensure constant long-term performance. With ARCTIC thermal pastes you will find the optimal viscosity for your application.
The surfaces of processor chips and cooler floors are covered with microscopic dents; ARCTIC's MX-4 thermal paste is composed of microparticles which fill these cavities. This leads to extremely high thermal conductivity, guaranteeing 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.
ARCTIC MX-4 is available in sizes ranging from 2 to 45 grams. Resealable packaging prevents the paste from drying out. While the packaging of our thermal paste has changed several times over the years, the composition of the formula has remained the same. Our MX pastes have long stood for high performance and quality, and with our new, recyclable packaging, we aim to reduce CO2 emissions and thus make a contribution to the environment.
ARCTIC's thermal pastes have always been one of the most popular products on the TIM market. To be able to ensure that a paste has been produced and filled under ARCTIC regulations and thus meets our high quality standards, we have the ARCTIC Authenticity Check. This means that every product can be reliably verified so that our customers are always on the safe side.
In contrast to pastes based on metal oxides or liquid metal, ARCTIC's MX-4 is metal-free and not electrically conductive.
