ARCTIC MX-4 Thermal Paste 4g with Spatula

8.5 W/mKNon-conductiveSpatula includedNo cure time

The ARCTIC MX-4 (part number ACTCP00031B) is the world-favourite carbon-based thermal paste rated at 8.5 W/mK, supplied as a 4g syringe with an application spatula for clean, even spreading. Non-conductive, non-capacitive and needing no cure time, it is a dependable, safe choice for CPU and GPU re-pastes. Typically in stock with fast delivery across Cyprus.

Compatibility — check before buying:
Compatible with any CPU or GPU cooler that uses standard thermal paste. MX-4 is metal-free, non-conductive and non-capacitive, so it will not short components if it spreads slightly beyond the die. Use the included spatula to spread a thin, even layer, or apply a small pea-sized amount and let cooler pressure do the work.

✓Everyday CPU and GPU re-pasting
✓Air and liquid cooler installations

✓Long-term builds (excellent durability)
✓GPU, console and laptop re-pastes
Key Features
 
Carbon-Based 8.5 W/mK Compound
MX-4 uses carbon micro-particles for a high 8.5 W/mK thermal conductivity, delivering efficient, consistent heat transfer between the die and cooler cold plate.
 
Spatula Included
This edition ships with a spatula for even, controlled application, making it especially handy for first-time builders who prefer to spread paste manually.
 
Non-Conductive & Non-Capacitive
The metal-free formula is electrically non-conductive and non-capacitive, so accidental contact with pins or SMD components carries no risk of shorting.
 
No Cure Time, Long Durability
MX-4 performs fully right away with no burn-in, and resists drying over years of use for a genuine set-and-forget install.

Frequently Asked Questions
What's included in the box?
A 4g MX-4 syringe plus an application spatula, so you can spread a thin, even layer manually without any extra tools.
Is MX-4 electrically conductive?
No. MX-4 is metal-free, non-conductive and non-capacitive, so it will not short components if it spreads slightly beyond the die.
Does MX-4 need to cure?
No. It reaches full performance immediately after mounting the cooler, with no burn-in period required.
Can I use it on a GPU or laptop?
Yes. MX-4 works on CPUs, GPUs, consoles and laptops — any component that uses standard, non-liquid-metal thermal paste.
Singular Expert Insight
This spatula edition of MX-4 is ideal for anyone who prefers to spread paste by hand, keeping all the strengths that made MX-4 a benchmark: strong 8.5 W/mK performance, safe non-conductive handling and long durability. It pairs with any air or liquid CPU cooler and suits any build behind a dependable power supply. For more performance, MX-6 or MX-7 step things up.
