Thermal paste sits between your CPU or GPU and the cooler, filling tiny surface imperfections so heat can move into the heatsink efficiently. ARCTIC’s MX-4 is one of the best known general purpose compounds in the brand’s cooling range, often compared with mainstream pastes bundled with coolers when you want a more consistent application and predictable temps.
Who is this for?
If you’re building a new PC, swapping a cooler, or refreshing an older system that’s running warmer or louder than it used to, MX-4 is a sensible go to. The carbon microparticle formula is electrically non conductive, which helps reduce the risk if a small amount spreads beyond the heatspreader. The included spatula suits people who prefer to spread a thin, even layer rather than relying on a single blob method.
- Size options: 4g (with spatula) or 8g if you service multiple PCs or GPUs.
