Prolimatech PK2 & PK3 Nano Aluminum Thermal Compound Review


Prolimatech PK2, PK3 TIM

We are only as strong as our weakest link, this becomes apparent when we start looking at our Thermal Interfacing Material (TIM), or commonly referred to as thermal paste/compound, because the cooling efficiency of our computers is greatly determined on how well the heat that is produced from a computer component (Ex. CPU) gets transferred to our heat sinks (Ex. CPU cooler).

When it comes time to choosing the right thermal paste/compound for our computer systems, we have a multitude of options that we can choose from. These choices range from the standard silicon based formula to the more elaborate silver based formulas, and just about everything in between. We also need to keep in mind that not all thermal pastes/compounds are created equal, some do very well while others fail miserably. So which brings us to how do we choose the right thermal paste for our computer systems. We can do one of three things to determine on what is the best thermal paste/compound for our computers: We can start purchasing various different types of thermal compounds and try each one out on our computer until we find one that best suits our computing needs, which will get rather costly and very time consuming. We can ask around in our favorite computer related forums for assistance, which will both help us and at the same time confuse us. To finally, we can start reading reviews of thermal paste/compounds at our favorite computer related review sites, for instance here at Legit Reviews. Or, we can do a combination of any of the above.

Over here at Legit Reviews, we happen to be looking at two newer additions of thermal paste/compounds from Prolimatech, the PK2, and the PK3. These two thermal paste/compounds come in three different volumes, 1.5g, 5g, and a large volume of 30g tubes. The volumes we will be looking over here at Legit Reviews are the 5g volumes of thermal paste/compound. The price ranges for the PK2 thermal paste/compound from 4.99 USD for a 1.5g tube, 11.99 USD for a 5g tube, 31.99 USD for a 30g. While the PK3 thermal paste/compound ranges from 6.49 USD for a 1.5g tube, 14.99 USD for a 5g tube, and finally 34.99 USD for a 30g tube, all volumes of Prolimatech’s thermal paste/compounds come with free shipping.

Prolimatech PK2 Volumes

Prolimatech Thermal Compound PK2 Specifications

  • Specific Gravity: 2.5g/cm
  • Adhesiveness: 250000Cps
  • Thermal Conductivity: 10.2 W/m-
  • Thermal Impedance: 0.015 -in/W
  • Included One syringe of thermal compound and one easy-spread card(1.5g)
    One Syringe of thermal compound and one easy-to-spread spoon(5g30g

Prolimatech Thermal Compound PK3 Specifications

  • Specific Gravity: 2.7g/cm
  • Adhesiveness: 330000 Cps
  • Thermal Conductivity: 11.2 W/m-
  • Thermal Impedance: 0.013 -in/W
  • Included: One syringe of thermal compound and one easy-spread card(1.5g)
    One Syringe of thermal compound and one easy-to-spread spoon(5g30g)

Given the specifications of each one of these thermal compounds, a quick look through the difference between these two thermal compounds (at least the only difference I am more concerned with) is that the PK2 thermal paste has a thermal conductivity of 10.2 M/w-C, while the PK3 thermal compound has a thermal conductivity of 11.2 M/w-C. In laymen terms, the higher the number in M/w-C means the better thermal conductivity of the thermal paste.

Prolimatechs Pk2 and Pk3 Packaging

Prolimatech keeps the packaging of the two thermal paste/compounds pretty simple. The only real difference between these two, in terms of packing, is the PK2 thermal paste comes in a green package (one on the right in image), while the PK3 thermal paste comes in an orange colored package (one on the left).

Prolimatech prints the general specifications of each thermal paste/compounds onto two sides of each packaging.

Then on the final side, Prolimatech prints the general features of the two thermal paste/compounds onto the packaging. The key features I am only concerned with are: Non-conductivity, and both of these thermal paste/compounds require no burn-in time, basically means that these do not require a lengthy period of time to get maximum results.
