About this item
- WELL PROVEN QUALITY: The design of our thermal paste packagings has changed several times over the years. The formula of the composition has remained unchanged, so our MX pastes have stood for high performance and quality for years
- HIGH PERFORMANCE: With excellent temperature reduction performance, the MX-4 is ideal for CPU and GPU cooling, and other applications between power semiconductor components and heatsinks
- SAFE APPLICATION: The MX-4 is metal-free and non-electrical conductive which eliminates any risks of causing short circuit, adding more protection to the CPU and VGA cards
- HIGH DURABILITY: In contrast to metal and silicon thermal compound, the MX-4 does not compromise over time. Once applied, you do not need to apply it again as it will last at least for 8 years
- EASY TO APPLY: With an ideal consistency, the MX-4 is very easy to use, even for beginners

After a number of external techs "fixed" my PS3 a couple times, only for it to die shortly after again, I decided to repair it myself.
I had to dismantle the entire console down to the motherboard, and literally bake it to fix any dry/broken solder runs. Yes, actually put it in the oven on full and bake it for 20/30 minutes.
Then when putting it back together, I used this thermal paste to install the CPU/GPU back on the board.
I did this a total of 5 times for about a year!! Eventually I gave up, because I got a PS4!
Even under general non-intensive usage, the laptop's cooling fan was spinning at noticeably higher speeds for longer & longer time durations to the extent it started to become annoying. At first I thought it was a BIOS update that messed with the fan's sensor. Something wasn't right. The uber-high RPM speed of the fan started generating a screeching sound indicating something was up with its bearings, cue time to open the laptop up and take a look.
Cooling fan had very minimal dust on blades but certainly no real reason to cause an impairment in cooling.
So I decided to take the opportunity to remove heatsink, clean-up previous compound and apply some Artic MX-4.
(I also took the opportunity to refurbish the fan by disassembling it, recoating the bearing surface with a drop of machine oil and put it all back together again whilst I wait for a new heatsink/fan assembly to be despatched from another vendor).
Everything was put back into place with MX-4 riding between the CPU and heatsink, Intel's XTU benchmark test was now reporting 80 degrees C maximum.
I ran the stress test, highest it ever got was 81 and with fewer instances of thermal throttling.
Impressed with the result given that it was achieved using all the original parts. Perhaps the slight refurbishing of the cooling fan played a part, but I attribute it largely to Artic's compound.
Research shows there are other cheaper or more exotic thermal compounds. I had narrowed my choice to Artic MX-4 or Thermal Grizzly's Kryonaut with its even higher heat conductivity of 12.5 W/m.
In the end given it was for use in a laptop that wasn't going to be overclocked, I opted for the friendlier, more consistent Artic MX-4, no fear of electrical conductivity and the advertised stable 8 year application lifespan.
For just under £5 for 4g tube, I think a 10-12 degrees temperature drop is a great result without having to worry about a yearly re-application.
Cooling fan now spins at even lower & quieter speeds whilst maintaining good temperature range.
Update:
Replacement heatsink/fan unit arrived. Everything removed and cleaned up, MX-4 reapplied and getting the same temperature drop, so the improvements I've witnessed are due to the Arctic MX-4, so I wholeheartedly recommend it as a safe way of making sure your CPU is given a good start in life.
I find that temps generally drop by 10c-20c after applying the paste. It may not be the best of the best but I don't want to test hundreds to find one better! Seriously, you will find it difficult to find better. I have read reviews from PC enthusiasts and seen looked at the comparisons of benchmark reviews. Don't be deceived by the claims of other TC companies, often they make what seem to be wild claims, at least in my experience I know that they certainly never performed any where near close to their claims.
If you want a reliable high performance thermal compound paste, that is safe to use, even if you are not good at applying paste on your chips plates, buy Arctic MX 4 and you won't be disappointed. I always buy the 20g tube. I noticed with this purchase that one indicator dot was already used but it did not appear (wasn't messy) like it had been used, I didn't bother weighing it, maybe I should have to be sure because the packaging isn't exactly tamper proof. To me, in my mind if a tube has a number of indicator dots showing you how full it is with paste then logic says all of those indicator dots ought to be full up! Mine wasn't with this most recent purchase, maybe they need to fix their labeling design, I don't know. I should pay better attention with my future purchase to be sure this is normal or not.
