Thermal Paste Showdown: Kingpin KPx vs. Thermal Grizzly – Does It Really Matter?

You’ve mapped out your custom loop, double-checked your tubing, flushed your radiators, and picked out a top-notch CPU block. Now, there’s just one last detail between your processor and your cold plate: the thermal paste.
 
PC builders often debate which thermal paste is best. Today, we’re comparing two top choices: Kingpin Cooling KPx and Thermal Grizzly’s Kryonaut and Kryonaut Extreme.
 
Both pastes are backed by well-known overclockers, Vince “K|NGP|N” Lucido and Roman “der8auer” Hartung, and both are on the pricier side. But for a daily water-cooled setup, does your choice really matter? Let’s find out.

Kingpin KPx Overview

KPx stands out with its bright blue color and was originally designed to handle the extreme conditions of liquid nitrogen overclocking. Over time, it has become a popular option for custom watercooling builds thanks to its ease of use and long-term stability.
  • Application: Very smooth and easy to work with.
  • Strengths: KPx spreads evenly with minimal effort, reducing the risk of air pockets or uneven coverage. It also performs well over time, resisting drying and “pump-out” caused by repeated heat cycles.
  • Considerations: As a more specialized product, availability can sometimes be more limited compared to widely distributed pastes.

Thermal Grizzly Kryonaut & Kryonaut Extreme Overview

Thermal Grizzly’s Kryonaut line has been a go-to choice for high-performance builds for years. The standard Kryonaut offers strong thermal conductivity, while Kryonaut Extreme pushes performance even further, targeting enthusiasts and overclockers.
  • Application: Slightly thicker consistency compared to KPx.
  • Strengths: Excellent thermal conductivity and strong benchmark performance when applied correctly. Widely available and commonly used across the enthusiast community.
  • Considerations: Standard Kryonaut may dry out over time in higher temperature scenarios. Due to its thicker consistency, it may require slightly more care during application.

Performance Comparison: Does Thermal Paste Matter in Watercooling?

In real-world custom watercooling setups, the temperature difference between Kingpin KPx and Thermal Grizzly pastes is typically very small—often around 1–2°C under load. Both options are designed for high performance, and either will be a major upgrade over basic or outdated thermal compounds.
 
For most builders, the decision comes down to factors beyond raw thermal numbers. Ease of application, long-term stability, and consistency over time tend to matter more than chasing marginal gains in peak performance.
 
Application quality plays a bigger role than brand choice. A properly mounted block with a well-applied thermal paste will outperform a poorly applied “top-tier” compound every time. Since draining and rebuilding a custom loop is time-consuming, long-term reliability should always be part of the decision.

Which Thermal Paste Should You Choose?

  • Kingpin KPx: A strong option for builders who prioritize ease of use and long-term consistency. Its smooth texture makes application straightforward, and it holds up well over time, reducing the need for frequent reapplication.
  • Thermal Grizzly Kryonaut / Extreme: A great choice for users focused on maximizing thermal performance, particularly in more extreme setups. Best results come with careful application.

FAQ: Thermal Paste for Custom Watercooling

Does thermal paste make a big difference in watercooling?
In most custom loops, the difference between high-end pastes is minimal. However, upgrading from a low-quality paste can significantly improve temperatures.

How often should you replace thermal paste?
For most watercooled systems, every 1–2 years is typical, depending on usage and temperatures.

Is Kryonaut better than KPx?
Both are high-performance options. The differences are small in real-world scenarios, so the better choice often comes down to application preference and long-term stability.

What matters most when applying thermal paste?
Even coverage and proper mounting pressure are more important than the specific brand used.

In the end, both options perform at a high level. Rather than focusing on minor temperature differences, choose the paste that fits your build style and maintenance preferences. With a proper mount and a well-designed loop, your cooling performance will be driven far more by your overall system than by the paste alone.
