Best Thermal Paste for Intel® Core™ i7-7700K Processor

Owning a mighty CPU like Intel® Core™ i7-7700K Processor implies that you’re an enthusiast who looks only for the top-notch components for your rig, which consequently means that your computer will often go through heavy workload conditions that require a solid cooling system to successfully dissipate the huge amount of heat generated by the processor.

Finding the right CPU cooler for this purpose is important, but also, on the other hand, getting a cutting-edge thermal paste is not less important. That’s because a thermal paste is solely responsible for transferring heat from the CPU to the heat-sink, and if this element is not functioning well enough, the whole process will be defective.

Recommending a thermal paste

So, what thermal paste do we strongly recommend for Intel® Core™ i7-7700K Processor?

In fact, there are plenty of very good thermal paste out there, but if you’re looking for the best of the best, then you have the following choices as the best thermal paste for Intel i7 7700k processor:

Thermal Grizzly Conductonaut

With the highest thermal conductivity of 73 W/mk, this liquid metal thermal paste tops our list in terms of performance (not overall features). Quick Review

Thermal Grizzly Kryonaut

This is the second best thermal paste as of today in terms of performance, and the best ever in terms of overall features. It’s a conventional paste with 12.5 W/mk thermal conductivity. The performance gap between this paste and the above is around 3 degrees only. (Quick Review)

Gelid Solutions GC-Extreme

GC-Extreme thermal paste has been for so long the best thermal paste on the market, and the most favorable to enthusiasts. Although many are still preferring it, it has lost its rank in favor of T.G. Kryonaut. This is a conventional paste with a thermal conductivity of 8.5 W/mK. (Quick Review)

Prolimatech PK3 Nano Aluminum

Prolimatech PK3 Nano Aluminum is one of the highest performing thermal compounds in the industry. It’s a conventional paste and boasts a 11.2 W/mk thermal conductivity with a competitive price. It’s a good choice for enthusiasts as well. (Quick Review)

ARCTIC MX-4

You cannot miss out this mighty thermal paste. Although it has become old and people are joking about its retirement, it is still a very popular thermal compound, even among enthusiasts themselves (traditional enthusiasts). It’s a conventional paste with a thermal conductivity of 8.5 W/mk. (Quick Review)

IC DIAMOND

You just wonder sometimes how some products are still living in the market although they are old enough to retire. This is the case with this conventional thermal paste that still proves itself as a high-quality CPU compound that won’t disappoint its fans. It has the lowest thermal conductivity 4.5 W/mk but with a great performance though. (Quick Review)


Thermal Grizzly Kryonaut

Thermal Grizzly Kryonaut CPU pasteThis thermal paste is currently the most popular among enthusiasts, and it occupies the top position of their choices as a high-end conventional paste. Thus, it’s our top pick for Intel® Core™ i7-7700K Processor and any other CPU intended for handling extreme workloads.

Official Description: Thermal Grizzly Kryonaut Thermal Paste was specially developed for extremely demanding applications and the most demanding of Overlocking community. Kryonaut also recommended as a top product for critical cooling systems for industrial use.

Kryonaut uses a special support structure, with no drying processes and starts at 80 ° C. This support structure ensures that the contained nano-aluminum and tin oxide portions of the paste combine perfectly and so any unevenness of the heat output (eg the CPU) and a heat sink are optimally compensated with outstanding thermal conductivity.

Feature Highlights

  • Delivers optimal heat transfer for larger-scale cooling systems, including water cooled systems
  • Designed with extremely demanding applications
  • Popular choice for overclockers and extreme gamers
  • Thermal conductivity 12.5 W/mk

Testimonials & Awards

After almost 6 years in lead of the market, GC-Extreme lost the battle against the new Kryonaut from Thermal Grizzly (talking about conventional paste)… Thermal Grizzly Kryonaut is the best normal paste on the market at the moment.

Thermal Grizzly is going up against some very tough competition, as there are a huge range of thermal pastes on the market to choose from and some of them have been proven and established for many years. Gelid GC Extreme is a popular choice for overclockers around the world, and we here at eTeknix have been using it for years in all our cooling tests, on our test benches and even in our own personal systems. I am happy to say that Grizzly is just that little bit better than GC Extreme, not so much so that I would feel compelled to take my cooler off and change my thermal paste, but close enough that you would find it’s a good alternative to GC Extreme.
