ARCTIC MX-4 is a thermal paste for transferring heat from a processor or graphics chip to its cooler. The 45 g syringe suits PC builders, enthusiasts and anyone who regularly maintains or services computer systems.

Its microparticles fill microscopic dents between the chip and cooler surfaces, helping heat move away efficiently. ARCTIC describes the paste as easy to apply, including for beginners, and says its non-drying and non-bleeding properties support consistent long-term performance. The metal-free formula is not electrically conductive, making it a practical choice where paste is applied close to sensitive components.

Key features

• Designed for heat transfer between CPUs or GPUs and their coolers.
• Microparticles fill small surface imperfections between mating surfaces.
• Non-drying and non-bleeding properties support long-term performance.
• Consistency is designed to make application straightforward, including for beginners.
• Metal-free formula is not electrically conductive.
• Resealable packaging helps prevent the paste from drying out between uses.
• 45 g syringe provides a larger quantity for repeated maintenance or multiple applications.

Compatibility

Use MX-4 between a processor or GPU and its cooler to improve thermal contact. It is a thermal compound, not a cooler, and the 45 g size identifies the quantity of paste. ARCTIC advises applying it carefully to avoid trapping air pockets between the processor and cooler. Good to know: the CPU or GPU cooler is not included; this product is thermal paste for use with a compatible cooler.
