Community Reviews

ARCTIC MX 4 is a dependable all purpose thermal paste that delivers strong cooling for the money, with real world repastes cutting laptop temperatures sharply and even fixing overheating and max fan behavior on an Xbox One X. It is also praised for staying consistently usable over time, especially compared with pastes that dried out or separated. The included spatula works, but the comments favor a very thin application instead of spreading it heavily, since too much paste can squeeze out or trap bubbles. A solid low cost tube if you want proven paste and do not need fancy extras.

I don't get the x- pattern thing, I use a credit card and do a thin later (about the width of construction paper) across the whole die evenly. It doesn't take much time and you're sure to more evenly distribute. Generally a pea size works, but depending on die size it could be more or less. And yes, gradually tighten it down the same way you would mount a tire.
The X pattern results in a more even film and ensures that it reaches the corners. This YT short isn't the one I originally saw, but it demonstrates the results in a quick video:

I might get the 45g version to last me the next 30 years.
I know they expire... My AS5 separated. I need to pull out the old mortar and pestle.

A pea size blob of thermal paste is way too much. And not by a little. That's probably 10 times what you actually need. If you're using a pea-sized dollop, you'll need to clean up a lot of squeezeout, if you can even get an optimal surface union.

Two surfaces that are flat like a processor and heatsink or memory chip and heatsink require less than a BB sized dot of paste, if spread properly.

Set up the hardware so the heat source is horizontal, facing up. Dot the surface with thermal paste in the center, then center the heatsink on it. Gently twist the heatsink back and forth, 45 degrees if possible, to get the surfaces to mate, then secure it in place using the X pattern mentioned if possible.

If you have some flat glass or clear plastic, you can use gel toothpaste to practice getting that thinner-than-a-sheet-of-paper layer to form evenly between two surfaces.

The spatula can be helpful, but if used as the primary method of spreading compound, you could easily cause bubbles and voids in the coverage if you're not careful.

I'm probably too careful. I'm sure they don't use that much care in the factories, but I like to optimize my system where it's cheap and easy to do so.

Quote from IraklisA View quoted comment :
I am an IT professional and highly recommend that you do not use a spatula when applying thermal paste. Due to the physics of how it works, you would ideally want the thinnest layer you can get while covering the most surface area. My preferred method would be applying a pea sized drop to the center, place the heat sink on it, then gradually tighten the screws in an X pattern (start with the top left, then bottom right, bottom left, and top right. Or any similar pattern)With thermal paste less is usually more, you only need a very small amount to enable the heat to transfer between the two and more mass would actually make it less efficient at doing this.
The spatula has worked better for me than a pea sized drop. Non issues ever.

Probably the best mix of price to performance and ease of use. In for one

This is a lifetime supply. Always wondered why they have to sell you so much of it?
This was a 3 month supply when I had the Xbox 360 red ring of death. Wink

I was reapplying seemingly twice a month.

*they latter came out with a bracket which solved the problem long(er) term.

Quote from lookalikehuuh View quoted comment :
I find it incredible how bad HP's thermal paste is. I bought an HP Envy 360 for my son with an AMD 5625u hexacore CPU, it was sooo loud, constantly running the CPU fans at what sounded to be full speed while he was just typing up a speech in Word. I got tired of hearing it while he sat on the dining room table doing his homework that I took it apart and removed the heatsink. There was a ton of thermal paste, and it was not dried out, but I went ahead and replaced it with MX-4. Somehow, the difference in the amount of fan noise is night and day. I used hwinfo64 and the CPU was idling around 60-70F now its down to 40F at idle.
I was very happy with the result, lowering the CPU temp by 20-30 Celsius with fresh thermal paste. I hardly hear the fan kick on anymore at idle.

haven't kept up with thermal pastes/compounds.
are there better performing and longer lasting options in this same price range?

Seems to me MX6 is about $2 more but a better thermal conductor. I used some expensive liquid metal (cybernaught?) when upgrading a amd 1600 to a 5600x about 3 or 4 yrs ago when a 5600x was $100. I noticed that when I went to change the build a bit, that shat stuff was impossible to get off. I first tried 90% isopropyl and a paper towel and the stuff just laughed at me. I tried naphtha, paint thinner, and even a scotch brite pad. All with out complete success. I finally went with the 0000 steel wool and that did not get the result I was looking for. JB weld is not as hard to get off (grin)...

I am staying with this stuff or artic 6 and staying away from liquid metal stuff. Reasonable price and performance with out the metal mess.

OK- I see your point, I still feel better about more evenly covering the die myself and determining the right thicknessof the paste

8g MX-6 is 8.88. 4g MX-6 is 5.99. with .50 extra, you'll get better MX-6. I don't see a specific reason to get that spatula and you don't actually even need a spatula. it spreads out pretty evenly when pressed by the cooler head. check some videos from LTT or other youtubers
