Arctic MX-6 (Pâte thermique, 4 g)

Non-conductive thermal paste for CPU and GPU, supplied with cleaning wipes: apply with no risk of a short circuit.

Level : Advanced

The MX-6 is a carbon-filled thermal paste designed for processors, graphics cards and consoles. It is non-conductive and non-capacitive: no risk of a short circuit if a little squeezes out over the chip. Its formula reaches peak performance right after application, with no burn-in phase. The 4 g syringe is enough for several re-applications, and six MX Cleaner wipes are included to remove the old paste cleanly.

What the community says

MX-6 is one of the most recommended pastes for a lasting build: its viscosity makes it slow to work but stable over time. That is the trade-off feedback consistently describes — you lose a little time spreading it, you do not reopen the PC two years later. The reservation concerns the packaging: the syringe is awkward and the paste tends to thicken if stored for a long time.

Strengths and highlights

→High viscosity that keeps it stable over time: the recurring argument, you do not reopen the machine after two years.
→Not electrically conductive, which limits the risk if it spills onto neighbouring components.
→Among the best price-to-quantity ratios in its class, 4 g syringes are more than enough for several applications.

Our verdict

The right compromise if you rarely dismantle and want a paste that goes the distance. For frequent rebuilds on a test bench, a thinner paste will save you time.

Frequently asked questions

Is there a risk if the paste spreads onto the motherboard?∨

No. The MX-6 is non-conductive and non-capacitive: unlike a metal-based paste, it does not create an electrical bridge even if a little spreads out. That is exactly what makes it reassuring for a first application.

How long does the paste last once applied?∨

Several years under normal conditions. The MX-6 has no burn-in phase: it reaches peak performance as soon as it warms up. You usually replace it during a big clean-up, not out of necessity.

Should I spread the paste or let the cooler pressure do the work?∨

Both work. Since the MX-6 is fairly thick, spreading a thin layer with a scraper gives a consistent result, especially on a large processor. A pea-sized dot in the centre, spread by the cooler pressure, also works very well.
