High-quality mid-range thermal paste from the well-known Swiss company Arctic. Supplied in a plastic syringe containing 20 g of product. This amount is enough for repeated installation of the cooler on the central or graphics processors. Depending on the area of the heat spreader cover or chip chip, it will be possible to perform from 20 to 40 installations. Recommended for advanced users and enthusiasts who often assemble and maintain personal computers, laptops and video cards on their own.

Also, ARCTIC MX-4 20g thermal grease can be used to improve heat dissipation from consumer and industrial power electronics (diodes and diode assemblies, mosfets), power controllers and other heating components. The service life of a correctly applied thermal interface guaranteed by the manufacturer is 8 years. Due to its moderate viscosity, this thermal paste well fills the microscopic irregularities of the contact surfaces and completely displaces air.

Excellent thermal conductivity and high upper temperature limit of use (up to 150 ºС) makes it a good choice for overclockers who practice overclocking using air and liquid cooling systems (not suitable for phase change systems using dry ice, freon, liquid nitrogen). It has a high electrical resistance, does not cause short circuits when it comes into contact with printed circuit boards.

Arctic MX-4 20g Premium Performance Thermal Compound for All CPU Air Coolers - Grey ACTCP00001B

Optimal Consistency for Every Application Depending on personal preference and area of application, a thinner or thicker t... morehermal 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. Highest Thermal Conductivity The surfaces of processor chips and cooler floors are covered with microscopic dents; ARCTICs 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. Easy Application Thanks to its consistency, MX-4 is easy to apply, even for beginners. The video below demonstrates the application technique to avoid air pockets between processors and coolers. Secure Usage In contrast to pastes based on metal oxides or liquid metal, ARCTICs MX-4 is metal-free and not electrically conductive. Available in Various Sizes ARCTIC MX-4 is available in sizes ranging from 2 to 45 grams. Resealable packaging prevents the paste from drying out. Proven Quality 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 CO 2  emissions and thus make a contribution to the environment. Often Copied, but Never Equaled 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.

Arctic Arctic MX-4 Thermal Compound (20g) ACTCP00001B

ARCTIC MX-4 is a new thermal compound that guarantees exceptional heat dissipation from components and maintains the needed... morestability to push your computer system to its maximum. Similar to the performance of existing and acclaimed ARCTIC MX-series, ARCTIC MX-4 continues to be overclocker’s ultimate choice when choosing thermal compounds. Prior to its introduction into the market, ARCTIC MX-4 has already received a Top Product Award from PC Games Hardware in a Germany print magazine in August 2010 as it prevailed against 11 other thermal compounds in the market. The ARCTIC MX-4 is a premium-grade thermal paste with exceptional performance and ease of application. It is an electrically non-conductive paste that is applied between CPU/GPU and designated coolers to transfer the dissipated heat from the components to the heat sink. Since the ARCTIC MX-4 is a metal-free compound, it eliminates the risks of causing short circuit and in turn adding more protection to your computer. The new formula in the ARCTIC MX-4 features optimal thermal conductivity and low thermal resistance. These characteristics effectively dissipate the emitted heat from the core components. The consistency of the ARCTIC MX-4 is designed for simple application. Its texture is just thin enough to spread onto components using fingers without creating much mess. - Easy Application- Optimal Thermal Conductivity- Low Thermal Resistance- Non-Electrical Conductive- Non-Capacitive- Non-Corrosive- No Curing- No Bleeding- Thermal conductivity: 8.5 W / mK- Viscosity: 870 poise- Density: 2.5 g/cm3

Suitable for CPU, GPU, laptops and consoles
13 December 2025 
Thermal paste that has long become a standard "smart solution" for servicing PCs and laptops. Used it for the processor, throttling disappears, the paste is easy to apply, doesn't run or dry out. I recommend it for use.
Good thermal conductivity for its class, non-conductive, 4g is enough for several applications, easy to apply.

Really good thermal paste at a nice price, took it and forgot
15 December 2024 
A truly popular thermal paste. It's not something incredible, but considering the price, it performs excellently in its functions. An ideal option for super-duper builds with increased cooling requirements.
Good thermal conductivity, convenient viscosity for application.
Considering the price, there are simply no drawbacks.
