ARCTIC MX-4 (4 g) - Premium Performance Thermal Paste for All Processors (CPU, GPU - PC), Very high Thermal Conductivity, Long Durability, Safe Application, Non-Conductive

I recently used Arctic MX-4 to repaste my Alienware m16 R2, and overall, I’m satisfied with the results. The application process was smooth — the paste spreads easily and doesn’t require much pressure, which made it user-friendly for a clean install on both the CPU and GPU dies.Performance-wise, I saw an immediate improvement in idle and load temps. Before the repaste, I was seeing idle temps around the high 50s to low 60s (in a warm room), and under load, temps would spike past 90°C pretty quickly. After applying MX-4, idle temps dropped to the mid 40s to low 50s depending on the fan profile, and load temps during gaming and light stress tests stabilized in the 80–85°C range with a few peaks under extreme loads, but nothing alarming.Fan noise also improved slightly due to reduced thermal load. It’s not a miracle paste, but for a non-conductive and affordable option, MX-4 holds its own. It’s especially ideal for users repasting a laptop like the m16 R2 where you want thermal reliability without risking electrical conductivity near VRMs or other tight board layouts.Final verdict: Arctic MX-4 is a solid choice for the Alienware m16 R2. Not the absolute best if you’re chasing top-tier benchmarks, but for everyday gaming and heavy use, it offers great thermal performance with low risk and easy application.

Years later and I'm still using this stuff. It lasts forever.I've noticed that the paste tends to last a couple years before it'll need to be changed out, which is something I try to do annually. I don't have to worry about that with this stuff.Works effectively to cool down everything from mini PCs to laptops to game consoles. Took my PS3 from 85 C down to 60 C after re-applying the old thermal past.

Essentially the best and only option.As I reassembled my CPU, I went to grab my usual tube of Artic Thermal paste, but alas. As I squeezed, there was none left.As I stood in shock elbow deep in my PC mid surgery, I quickly used my messenger pigeon to go order another tube of this 5 star quality Artic thermal paste.Only mere moments later, I was gifted another tube to then only have to use only a pea sized drop from a fresh new tube. Truly a godsend, finally relieved I finished assembling my PC. Now I can sleep peacefully at night knowing Artic’s thermal paste is cuddling my CPU keeping it cool and fresh.Thanks Artic you beautiful beautiful company.

This stuff worked great and I still have a lot left. You’d probably be able to do a few CPU’s with just one. I messed up and had to redo it and I still have a quarter of a tube. I love the gauge that shows you how much is left

Works pretty good so far lowered my temps by 15C!

Went on effortlessly and was not too dry, love the scratch off QR code to make sure it is an official product. Performance so far has been great allowing my AIO to keep the Ryzen 9 cool. They're is enough for several applications if you have more than one PC. Highly recommend!

Havent used it yet, but have used in the past and always does as expected, so I hope it does this time as well.

Excellent thermal compound! The ARCTIC MX-4 (4g) is a high-performance, easy-to-apply paste that significantly improves heat transfer for CPUs and GPUs. It spreads smoothly and provides reliable cooling, helping keep my components running cooler and quieter. Great quality and value for any DIY PC builder or upgrader. Highly recommended!
