4.0 out of 5 starsGood compound - although a few things you should know before buying
By Tj on 16 Feb. 2013
Size: MX-4 4G Verified Purchase
Bought Arctic this Cooling MX-4 4g Thermal Compound, for the
Arctic Cooling Freezer 7 Pro Rev.2 CPU Cooler I bought from here also

http://www.amazon.co.uk/gp/product/B002G392ZI/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1

to compliment an old intel socket 775 quad core (these things get hotter than h*ll if not fitted properly)
the quad core had recently been treated with arctic silver 5, again a great compound although AS5 can be corrosive and damage your board if spilled, The CPU is not overclocked and is running 35 degrees idle and under 45 degrees on full load, it has only reached 56 degrees during extensive torture testing and benchmarking with a 10% overclock applied (all cpu's of all ages should run no hotter than around 70 degrees on a maximum load - any higher replace your cooler and get this pronto),

Pro's & Cons

MX4 isn't as corrosive or as messy as AS5
MX4 is as good as AS5 although some might get a degree or 2 cooler with AS5 under full load as I did
MX4 doesn't take an age to cure, you see the improvements within a few hours instead of days/weeks

Application (Important for those first time users)

Never use a spatula or your finger to spread a thermal paste on the CPU. (This contaminates the paste)
Always put a small pea-size compound on it and let the pressure of the heat sink spread it. Also don't twist it.
That way there is less risk of trapping air and creating an uneven layer between the CPU and the heat sink.

If it is your first time applying a cooling compound you should watch a video for basic instructions

[...]

This tube should be enough for 4-6 applications, remember to thoroughly remove all traces of the old compound before application and if you have purchased a new heat sink to clean any manufacturer pre-applied paste of also, as it is usually low budget cheap cr*p they supply with them.

5.0 out of 5 starsGreat product at a good price that solved my overheating issues
By Toastlord on 25 July 2016
Size: MX-4 4G Verified Purchase
My AMD 8320 processing in my PC was consistently reporting CPU temperature's in the high 60's and 70's, despite everything being pretty much stock and not overclocked, so I suspect new thermal compound was need to bring the temps down. Despite working in the IT field I'm a bit of a novice when it comes to thermal compounds, so purchased this on the back of a number of excellent reviews. The price was good and delivery time quick (think it was about 3 days from ordering via standard delivery - I didn't go for Prime as I wasn't in a huge hurry and the Prime option from another supplier was a couple of pounds more for the same product.

It's dead simple to apply and use - there's plenty of you tube videos if you are unsure but basically clean the surface of the processor and the heatsink well first, apply a pea sized blob and you're done. Don't try to spread it with a credit card or similar, there's no need and that can introduce air bubbles which render it inefficient.

As I suspected the MX-4 has done the trick and the CPU temperature is now way lower than is was, sitting in the low 40's now even when under stress.

One word of warning, I had real issues separating the CPU from the heat sink as the manufacturer had used thermal adhesive to stick the two together. It was stuck so hard that when I tried to pull it apart it actually pulled the CPU from the motherboard instead, bending a number of pins in the process! It was still a nightmare to prise the two apart, even when off the motherboard, and then I saw had bent pins all over the shop much to my dismay. After a few minutes swearing and panicking I was able to realign them with the old credit card trick to straighten them, but it was a proper heart in mouth moment for a while there!

5.0 out of 5 starsUp there with the best
By Antoine HALL OF FAMETOP 50 REVIEWER on 14 Aug. 2015
Size: MX-4 4G Verified Purchase
I have been using Arctic Cooling thermal compounds for over a decade on practically all my computer builds. It is only lately that I have also started using the Noctua NT-H1 for those very demanding CPUs and GPUs. However this comes at a price.

Now the MX-4 claims to be even better than the Noctua, (as seen in the photo) yet some would agree that this is not the case. Having said that the difference in thermal dissipation between the two is minimal.

I still use use Arctic Cooling on 99.9% of my builds. It spreads easily, is non corrosive, cures in no time and lasts for years. Don't get me wrong, I'm no professional yet I do many computers builds for friends and gained some experience in the process:

A few tips:

• A little paste can go a long way. If you apply too much than you create an insulator rather than a conductor.
• Apply pea shaped but NOT pea sized. As Linus says, it should be the size of a grain of rice. Haswell E CPUs require a bit more
• Always make sure that the surface of the CPU is clean prior application. IPA 99.9% alcohol applied with a lint free cloth works best
• Take great care not to get any compound on braided water cooling (all in one) pipes. It will be very difficult to remove
Bottom line: The MX-4 is amongst the best thermal compounds available, offering excellent price to performance ratio

Got a good 8c drop after replacing the old TIM with the MX-4. I've managed to push my Phenom II X4 955 up to 3.50GHz.

5.0 out of 5 starsExcellent paste
By Amazon Customer on 17 May 2016
Size: MX-4 4G
After researching which thermal paste was best for my CPU this came up top. The paste is really easy to use and will last ages. I have used it on 5 or 6 CPU's and still have some left.
The best method to apply the paste is to squeeze it onto the middle of the CPU like a grain of rice. This way will ensure all cores are covered and will provide the best results.
