Spatula, 4 g) - Premium Performance Thermal Paste using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. ARCTIC's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Is ARCTIC MX-4 electrically conductive?
No. ARCTIC states MX-4 is metal-free and non-electrically conductive, which eliminates short-circuit risk if some contacts a CPU socket or VGA card.
How much is 4 g of MX-4 good for?
ARCTIC does not publish an application count for the 4 g syringe. A standard desktop CPU application uses well under a gram, so most builders get multiple repastes out of it.
Does it come with an applicator?
Yes, a spatula is included in the package so you can spread a thin, even layer instead of relying on the dot-and-press method.
Can I use MX-4 on a GPU as well as a CPU?
Yes. ARCTIC lists MX-4 for all processors including CPU and GPU, and its non-conductive formula is specifically called out as added protection for VGA cards.
How do I know my syringe is genuine?
Every MX-4 package includes an ARCTIC Authenticity Check, letting you verify the individual product is 100 percent original before you apply it.
