Pros & Cons
Pros
- ✓ Metal-free, non-conductive formula - spillover near GPU SMDs won't short anything
- ✓ 8 g tube covers many CPU mounts or several full GPU repastes
- ✓ Carbon microparticle compound rather than silicone-only filler
- ✓ Spatula included, so no scavenging a card or plastic scraper
Cons
- ✗ Non-metallic paste trails liquid metal on raw conductivity
- ✗ Thin consistency can spread past the IHS edge if you overapply
- ✗ No included isopropyl wipes for cleaning the old paste off
- ✗ Authenticity Check only helps after purchase, not before
Manufacturer description
The compound uses carbon microparticles rather than metal, so thermal conductivity stays high while the paste remains non-electrically conductive. That matters the moment a bead squeezes past the edge of an IHS or lands on the exposed SMDs around a GPU die: with MX-4 there is no short-circuit path, which is exactly the margin you want when reseating a graphics card cooler for the first time. ARCTIC ships this 8 g package with a spatula, enough compound for many CPU applications or several full GPU repastes, and the consistency is thin enough to spread without warming the tube first. That…
SpecPicks Verdict
SpecPicks scored ARCTIC MX-4 (incl. Spatula, 8 g) - Premium Performance Thermal Paste… 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. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Is ARCTIC MX-4 electrically conductive?
No. MX-4 is metal-free and non-electrically conductive, so paste that squeezes out onto the PCB or surrounding components will not cause a short circuit.
How many applications do you get from the 8 g tube?
8 g is a large tube by thermal-paste standards - enough for many CPU applications or several complete GPU cooler repastes, depending on die size and how much you apply.
Can I use MX-4 on a GPU as well as a CPU?
Yes. ARCTIC rates MX-4 for all processors, including CPUs and GPUs on PCs, and the non-conductive formula is specifically called out as protection for VGA cards.
Is MX-4 easy to apply if I have never repasted a cooler?
ARCTIC designed the consistency for beginners and includes a spatula in this package, so you can spread a thin even layer instead of relying on cooler pressure alone.
How do I know the tube I received is genuine ARCTIC paste?
Every unit supports ARCTIC's Authenticity Check, which lets you verify the individual product is original. Check the product listing for the current verification instructions.
Key Features
