What the product is and who it serves

Arctic MX-4 2019 Edition is a carbon-based thermal compound supplied in a 2.0g syringe. It is intended for PC builders and overclockers who need reliable heat transfer between a CPU or GPU and its cooler without the risk of electrical conductivity. The paste contains no metallic particles, so accidental contact with pins or traces will not cause a short circuit. Its consistency is designed for easy spreading even for first-time users.

The specification that decides fit

Thermal conductivity is rated at 8.5 W/mK, which is the single figure that determines whether this compound meets a build's cooling requirements. The operating range spans -50 °C to +230 °C, covering extreme sub-ambient and high-load scenarios. The 2.0g volume is sized for a few applications on standard desktop processors. No metallic content means it is safe for use on exposed die surfaces and around sensitive components.

Behaviour under sustained load

The compound maintains its performance over the service life of a typical gaming rig, resisting pump-out and drying that degrade lesser pastes. Carbon micro-particles provide stable thermal transfer during extended heavy workloads without hardening or separating. Long-term stability is a highlighted characteristic, so re-application is rarely needed before the system is retired. It is not suited for buyers who require a larger volume for multiple builds or industrial-scale maintenance.

Questions about this item

How does the 8.5 W/mK conductivity translate when the paste is between a CPU and cooler?

The 8.5 W/mK rating means heat moves efficiently from the die to the heatsink, keeping temperatures lower under sustained load compared to standard compounds.

Is the MX-4 electrically conductive like liquid metal pastes?

No, the carbon micro-particle formula contains no metallic particles, so accidental contact with pins or traces will not cause short circuits.

Will the 2.0 g syringe cover a large desktop CPU and GPU?

Yes, 2.0 g is enough for multiple applications on standard desktop processors and graphics cards using a pea-sized dot each time.
