Proven thermal compound for enthusiasts

ARCTIC MX-4 2019 Edition is a high-performance thermal paste designed for CPU and GPU cooling. Its carbon microparticle formula delivers 8.5 W/mK conductivity without any metallic particles, eliminating electrical conductivity risk. The compound targets overclockers and extreme gamers who need reliable heat transfer for demanding workloads.

Syringe format simplifies installation

The 4.0 gram syringe allows precise application directly onto the processor heat spreader or cooler base. Its consistency helps beginners avoid air pockets during mounting, and the non-metallic composition means no curing time is required. The paste fits standard desktop and laptop maintenance routines where a thin, even layer is needed between die and heatsink.

Stable output across extreme temperatures

Rated for continuous operation from -50 °C to +230 °C, the compound maintains its thermal properties under sustained heavy loads without drying out or degrading. Independent magazine awards confirm consistent performance over the typical service life of a gaming system, so a single application remains effective until the hardware is retired.

Questions about this item

At what point does the MX-4 2019 Edition reach its thermal conductivity limit under sustained heavy loads?

The compound is rated at 8.5 W/mK and remains stable across an operating range of -50 °C to +230 °C, so it does not hit a conductivity ceiling within normal sustained use.

Does the paste dry out, pump out or become noisy when the system runs all day at high temperature?

It contains no metallic particles, resists drying and pump-out, and is designed to last beyond the service life of the rig without degradation or added noise.

What cooler mounting hardware or cleaning supplies must I already have to apply the 4.0 g syringe?

You need a compatible CPU or GPU cooler, isopropyl alcohol and lint-free cloth for surface preparation, and the syringe itself includes a spreader for even application.
