Today we have a new product from Arctic Cooling, the Arctic MX-3 Thermal Compound, which aims to takes the already good performance of Arctic Cooling's MX-2 Thermal Compound to the next level. Arctic MX-3 thermal compound is composed of carbon micro particles and boasts an extremely high thermal conductivity, which unless your some sort of scientist probably doesn't mean a whole lot to you, however in this article we'll see what this means in terms of performance and if at the end of the day it can help decrease our CPU temperatures.

It wasn't too long ago that we took 6 of the most commonly available thermal pastes and put them head to head and tried to crown a winner (you can read the full article over here). The difference between the 6 thermal pastes was pretty small, and all provided a decent increase over the stock thermal paste that came with our stock AMD cooler. It will be very interesting to see how the Arctic MX-3 stacks up against the rest of the competition.

Let's take a closer look at the Arctic MX-3 and see what it's all about.

Arctic MX-3 looks pretty standard, it comes in a tube, and its grey like pretty much every other thermal compound available. As you can see in the picture below the consistency of the Arctic MX-3 is very nice, and you can see with the others one is a touch too runny while the other is a bit more dry, and when you compare the 3 pictured the Arctic MX-3 is the easiest to apply.

Arctic Cooling MX-3 Thermal Compound Specifications:

Unparalleled thermal performance
As an upgraded version of the award-winning ARCTIC MX-2, the performance of the ARCTIC MX-3 outranges other well-known thermal compounds clearly. This new compound is composed of carbon microparticles which lead to an extremely high thermal conductivity – 8.2 W/mK. It guarantees that heat from the CPU or GPU can be dissipated quickly and efficiently.

The ARCTIC MX-3 is a metal-free, non-electrically conductive compound which does not cause any damage of the components if it is accidentally spilled out on them. It eliminates any risks of short circuit and provides more protection to the CPUs, graphic cards and other applications between power semiconductor components and heatsinks. The ARCTIC MX-3 is a truly hassle-free premium thermal compound you can rely on.
