Installing this paste is just like any other tube. It's easy and very straightforwards. Arctic has had MX-4 on the market for a very long time, and it's a well-regarded paste for it's good quality and longevity. It's not too sticky, and being silicon-based, you can install it on just about anything, making it compatible with just about any electronics. Being a 4 gram tube, the excretion hole isnt too large, meaning you get the perfect thickness, allowing for better thermal conductivity. Rock solid paste, would buy again.

I've used the ARCTIC MX-4 thermal paste for a recent CPU upgrade, and overall, I'm very satisfied with the results. The paste comes in a well-sealed syringe that makes application easy and mess-free. It spreads smoothly without being too runny or too thick, which is especially helpful for first-time users or those reapplying paste during a maintenance cycle. In terms of performance, it significantly improved my CPU temperatures compared to the old paste I replaced—about a 6–8°C drop under load, which is solid for a mid-range setup. I haven’t tested it in extreme overclocking scenarios, but for general gaming and productivity, it’s more than sufficient. One thing I appreciate is that it’s non-conductive, so there’s less worry about shorting anything if a bit of paste spills near sensitive components. Durability claims are long-term, and while I can’t verify longevity yet, the brand has a good reputation in that area.

Ah yes, the ARCTIC MX-4 — the crème de la crème of thermal pastes, or at least that's what it tells its mirror every morning. Packaged like a syringe full of high-performance dreams, this 4g tube promises to make your CPU so chill, it’ll start quoting Zen poetry and demanding herbal tea. Let’s start with the basics: carbon microparticles for “extremely high thermal conductivity.” Translation: it’s like tossing your overheating processor into a snowbank but without the lawsuits. It claims to be non-conductive and safe to apply, which is tech-speak for “even your clumsiest cousin can’t screw this up.” (Probably.) Application? Smooth. So smooth, you might be tempted to moisturize with it. Don’t. But seriously — it spreads easier than gossip in a small town and stays put like it just signed a five-year lease on your CPU. Now let’s address the hype: does it work? Yes. CPUs are reporting temperature drops like it’s a competition. One user’s PS3 went from lava flow to gentle breeze. Another claimed it outlasts most Hollywood marriages. Big words. Bigger cooling. But beware: there’s a newer MX-6 in town, and it’s got better specs on paper — but let’s be honest, MX-4 is the people’s champion. Affordable, reliable, and with enough paste for multiple builds (or one spectacular accident). Final verdict: If your processor’s feeling spicy, MX-4 is the culinary cooling wizard it deserves. Apply generously. Bask in the silence. Pretend you’re a tech god.
