Pros & Cons
Pros
- ✓ Lower thermal resistance than MX-4 - ARCTIC cites about 20% better performance
- ✓ Non-conductive and non-capacitive, so spills near pins will not short
- ✓ 4 g syringe covers many applications, not a single-use dab
- ✓ Viscosity works for direct-die GPU and console CPU packages
Cons
- ✗ No included spreader tool or spatula in the standard 4 g package
- ✗ Thicker than MX-4, so it takes more mounting pressure to spread evenly
- ✗ Non-metallic paste still trails liquid metal on peak delta-T
- ✗ ARCTIC does not publish a W/mK figure, only relative claims vs MX-4
Manufacturer description
The ARCTIC MX-6 thermal paste is a 4-gram syringe built for people who care about the last few degrees. ARCTIC positions it as a measurable step up from the long-running MX-4: an improved composition gives the MX-6 lower thermal resistance, which the company quantifies as roughly 20% better performance. That matters most when you are re-pasting a CPU that throttles under sustained load, or reviving a laptop whose factory paste has dried out after a few years. Because the MX-6 is neither electrically conductive nor capacitive, a stray smear on nearby SMD components or socket pins will not…
SpecPicks Verdict
SpecPicks scored ARCTIC MX-6 (4 g) - Ultimate Performance Thermal Paste for CPU… using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. ARCTIC's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cooling & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How much better is the MX-6 than the MX-4?
ARCTIC states the MX-6's reworked composition has a measurably lower thermal resistance than the MX-4, which it markets as roughly 20% better performance. Actual delta depends on your cooler, mount pressure, and load.
Is the ARCTIC MX-6 electrically conductive?
No. ARCTIC states the MX-6 is neither electrically conductive nor capacitive, so paste that squeezes onto surrounding components or socket pins will not cause a short circuit or discharge.
Can I use it on a GPU or a game console?
Yes. ARCTIC lists graphics cards, consoles, laptops, and CPUs as supported, and notes the viscosity suits direct-die cooling on bare GPU and console processor packages.
How many applications do you get from the 4 g tube?
That depends on die size and application method - a large heat-spreader CPU uses more than a bare laptop die. The 4 g size is the mid-tier tube in ARCTIC's lineup, aimed at repeat re-pastes rather than a single build.
How do I know the tube is genuine?
ARCTIC includes an Authenticity Check with every unit, so each individual product's authenticity can be verified against ARCTIC before you apply it. Check the product listing for the current verification steps.
