One of the best branded thermal pastes from the Swiss company Arctic in a syringe format containing 4 g of paste. It is part of the legendary Arctic MX series of thermal interfaces, which have pleased users with high technical specifications and impeccable product quality for over a decade. It is positioned as a mid-range product targeted at DIY enthusiasts building PCs themselves and overclockers.

The thermal paste is essential for significantly improving heat transfer from a heated electronic component (such as a power transistor, chip, CPU, or GPU) to the heatsink of the cooling system. It fills in micro-irregularities on touching surfaces, removing air from them — a good thermal insulator. The ARCTIC MX-4 4g thermal paste is intended for use in cooling systems of central and graphics processors in personal computers, laptops, and high-performance graphics cards.

It contains carbon microparticles that reduce thermal resistance of the contact area and ensure maximum heat dissipation efficiency. It has high thermal conductivity (8.5 W/m∙K) and stability up to 150 ºC, this thermal paste is a good choice not only for enthusiasts and overclockers but also for other applications requiring direct heat transfer.

Arctic MX-4 4g Enthusiast Performance Thermal Paste for All CPU/GPU ACTCP00002B

Arctic MX-4 Enthusiast Performance Thermal Paste A sustainable use of resources is really important for us at ARCTIC Thus w... moree updated the packaging of the MX-4 to minimize it's CO2 Footprint. The practical, recyclable packaging bag of our thermal compound helps us to reduce the environmental impact of packaging materials by about 40% and thereby save resources. Better Than Liquid Metal The ARCTIC MX-4 compound is composed of carbon micro-particles which lead to an extremely high thermal conductivity. It guarantees that heat generated from the CPU or GPU is dissipated quickly and efficiently. Superb in performance, MX-4 is the best companion for overclockers and enthusiasts. High Durability In contrast to metal and silicon thermal compound, the performance of MX-4 does not compromise over time. Once applied, you do not need to apply it a second time as it will last at least for 8 years. Value for Money A high performance thermal compound perfect for system builders, there's no suprise that the MX-4 exceeds your expectations for its low price tag. Easy To Apply With an ideal consistency, the MX-4 is very easy to use, even for beginners. The possibilities for its application and the most effectively way to avoid voids between CPU and cooler we show you in the video. Safe Application It does not contain any metallic particles so electical conductivity would not be an issue. Unlike silver and copper compound, it ensures that contact with any electrical pins would not result in damage of any sort. Features Thermal Conductivity 8.5 W/(mK) Viscosity 870 poise Density 2.50 g/cm³ Volume Resistivity 3.8 x 1013 O-cm

Arctic Arctic MX-4 Thermal Compound (4g) ACTCP00002B

Arctic Cooling, is best known for its very quiet and inexpensive CPU cooler. To make the transfer of heat from the processor... moreto the cooler as efficient as possible, the engineers did not rely on third-party products, but quickly developed their own thermal compound. In addition to the high performance, the focus was on practicability. Arctichas now launched a whole range of thermal compounds on the market and is continuing its evolution with the MX-4 . The thermal conductivity was increased from 8.2 W / mK to 8.5 W / mK compared to the MX-3 . With four gramsThere is a lot in the syringe that is sufficient for a few uses. In addition, the thermal compound dispenses with metallic ingredients and consists of carbon microparticles . The main advantage of this composition is that the paste is not conductive and accidental short circuit is excluded when the paste gets to other parts of the hardware. The application is thus much more relaxed. The manufacturer also pays attention to sustainability when it comes to packaging: The production of the new, recyclable packaging has reduced environmental emissions by 40 percent, The new packaging is also lighter than before. Technical details:- Content: 4 g- 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.
