When buying a computer system that’s pre-built, there’s not much you really need to worry about apart from it working as soon as it’s plugged in. When building your own however, there’s a lot more involved from choosing the right components and importantly keeping it nice and cool.

To keep a system cool it’s not just a matter of finding the right CPU cooler and fans, but a vital choice lies in what thermal paste is used. This ranges in what materials are invested into the product such as silver or diamond and the price for the particular paste and obviously what your budget allows you to purchase.

Arctic Cooling have developed their MX-4 paste based off of its predecessor; MX-3 but with a few improvements, which mainly include keeping similar performance as the MX-3 paste whilst keeping costs to a minimum and have easier spread-ability.

For a brief history lesson, Arctic include several blocks of information including a bit about their history:

The increased heat emission of modern computers has put the production of powerful and quiet coolers beyond the means of most manufacturers. The raised noise levels of PC systems have a negative impact on productivity, since a quiet computer is the basis for pleasant working conditions. ARCTIC initiated the trend towards quiet cooling systems for desktop PCs in 2001 and has led the way ever since. When ARCTIC COOLING was founded, we began by focusing on Switzerland and Germany. In 2002 ARCTIC COOLING (HK) Ltd. was founded to develop relationships with our Asian production locations. From 2005, we started to expand business in North and South America and provide optimum service to our customer base there.

ARCTIC is now a leading manufacturer of CPU coolers, GPU coolers and case fans. In recent years we acquired a far-ranging expertise in the field of consumer electronics. The company’s product range has been further enhanced by new lines unrelated to PC cooling which was the reason behind the 2010 change in our brand name and logo: ARCTIC COOLING became the ARCTIC brand umbrella.
