Prolimatech Pk-3 Nano is one of the most reliable thermal compound pastes to maximize the heat transfer between heatsink and processor. The Prolimatech claims that this product has longer stability and low dry-out time. So, in this review of Prolimatech Pk-3 Nano, we’ll test and find out if it’s really worth buying this thermal paste or not.

Prolimatech Pk-3 Nano Aluminum Review
The Proliamtech Pk-3 Nano thermal compound comes in 1.5g, 5g, and 30g tubes. For the purpose of testing this product, we bought a 5g tube from Amazon. Just to let you know, a 5g of thermal paste will last for a few years if you know how to apply it correctly.
To be honest, this is one of the best thermal pastes that I’ve tested so far. If anything is better than this, then it could be IC Diamond 24 Carat thermal paste that uses small diamonds to make great contact with your components.
However, this thermal paste is composed of nano-sized aluminum particles that fill out the gap between the processor and heatsink for better contact and efficient heat transfer. This technology also eliminates the creation of air bubbles that negatively impact the cooling mechanism. The nano-particle fills the air gaps and promotes higher heat transfer.
As the Pk-3 is non-conductive, so you can apply this thermal paste between IHS, copper, aluminium, or nickel circuits. So, you can use this thermal paste on many desktop computers, laptops, and video cards that need efficient cooling.
Low-Dry Out time
The material inside the Pk-3 doesn’t dry out even if you keep using it once a year. However, make sure to keep it in a cool or dry place away from the sun. However, this thermal paste as compared to others takes more time to spread on a surface. It’s not as “liquidy” as other high-quality thermal pastes on the market. It’s not too hard to apply, but it’s also not too much of a liquid as well.
But all in all, it’s super simple to apply this paste to your components without any effort.
For testing the performance of Prolimatech Pk-3 Nano Aluminum thermal paste, we opted for a Core i9 9900K CPU and Cooler Master Hyper 212 EVO CPU Air Cooler. We applied the pinch of this paste at the base of the Hyper 212 EVO cooler and then mounted it on the Core i9 9900 CPU.
After running benchmark tests, we found that temperatures were below normal most of the time even when playing games. As the CPU was running at stock speed and we opted for one of the best CPU coolers in the market, the Hyper 212 EVO which has 4 direct pipes attached to the base for better thermal conduction.
However, before applying the Pk-3 Nano Aluminum thermal compound, the temperature was going up and down between 50 and 70 Degrees Celsius. But after the application of Pk-3 thermal paste, the temperature went down to 45 to 50 Degree Celsius.
When compared with other high-end thermal pastes like Arctic Silver 5 and Grizzly Kryonaut, we found the Pk-3 Nano Aluminum great in lowering the temperature by a few degrees.
- Excellent Cooling
- Lasts for years
- No reapplication is needed for years
- Prevents air bubbles
- Does not spreads easily
- Needs more mounting pressure for better contact
The Final Verdict
Prolimatech Pk-3 Nano Aluminum is a reliable and long-lasting thermal paste in the market. You can apply this paste on most hardware that uses thermal paste for efficient heat transfer. It’s a little bit pricy and hard to spread as compared to other brands, but it is worth the price you pay for it.
