Pros & Cons
Pros
- ✓ Metal-free carbon microparticle formula - non-conductive, no short-circuit risk on spills
- ✓ 8 g syringe covers many applications, not a one-shot tube
- ✓ Soft consistency spreads under mount pressure without a spatula
- ✓ ARCTIC Authenticity Check verifies each tube is genuine MX-4
Cons
- ✗ Carbon-based, so it trails liquid metal compounds on extreme overclocks
- ✗ No spatula, alcohol wipes, or cleaning supplies included in the box
- ✗ Soft texture can smear if you overfill the die area
- ✗ 8 g is more than a single-build owner will ever use
Manufacturer description
The compound is built on carbon microparticles rather than metal, so it moves heat off a CPU die or GPU package quickly while staying completely non-conductive. That matters the moment you overshoot the pea-sized dot and paste creeps onto SMD components or the socket edge: with MX-4 there is no short-circuit risk to clean up after. The 8 g syringe is sized for repeat work rather than a single application, making it a sensible pick if you maintain several rigs, refresh an aging gaming PC, or plan to delid and reseat more than once. ARCTIC keeps the consistency soft enough to spread under…
SpecPicks Verdict
SpecPicks scored ARCTIC MX-4 (8 g) - Premium Performance Thermal Paste for All… 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
Is ARCTIC MX-4 electrically conductive?
No. MX-4 is metal-free and non-electrically conductive, so paste that slips onto the socket edge or nearby components will not cause a short circuit.
How many applications do you get from the 8 g tube?
The 8 g syringe is the large size and is intended for repeated use across multiple CPUs or GPUs rather than a single build. Exact coverage depends on your die size and application method.
Can I use MX-4 on a GPU as well as a CPU?
Yes. ARCTIC rates MX-4 for all processors, covering CPUs and GPUs on both desktop PCs and VGA cards.
Is MX-4 beginner-friendly to apply?
Yes. ARCTIC designed the consistency to spread easily under cooler mount pressure, and the listing specifically calls it easy to use even for first-time builders.
How do I know my tube is genuine and not a counterfeit?
Every MX-4 unit supports ARCTIC's Authenticity Check, which lets you verify the individual product. Check the product listing or ARCTIC's site for the current verification steps.
