Does NZXT Kraken Come With Thermal Paste? Unveiling the Cold Truth
The short answer is yes, almost all NZXT Kraken all-in-one liquid coolers come with thermal paste pre-applied to the cooler’s cold plate. This makes installation easier and faster for the average user.
The Importance of Thermal Paste for Your Kraken Cooler
Thermal paste, also known as thermal grease or thermal interface material (TIM), is a crucial component for any CPU cooler, including the NZXT Kraken. Its primary function is to fill the microscopic gaps and imperfections between the CPU’s integrated heat spreader (IHS) and the cooler’s cold plate. Air is a poor conductor of heat; therefore, the thermal paste facilitates efficient heat transfer from the CPU to the cooler, ensuring optimal cooling performance and preventing overheating. Without it, even the best cooler, like an NZXT Kraken, would be rendered largely ineffective.
Why Pre-Applied Thermal Paste is a Convenience
NZXT’s decision to pre-apply thermal paste to its Kraken coolers is a consumer-friendly choice. It simplifies the installation process, especially for users who are new to building or upgrading PCs. It removes the guesswork of how much paste to apply and reduces the risk of applying too much or too little, both of which can negatively impact cooling performance. This pre-application helps ensure that even novice users can get the most out of their NZXT Kraken.
Checking for Pre-Applied Thermal Paste on Your Kraken
Before you start the installation process, always visually inspect the cold plate of your NZXT Kraken. You should see a thin, even layer of gray or white thermal paste. If the cold plate appears clean or if the paste is damaged or uneven, you’ll need to clean the old paste and apply new thermal paste. You can use isopropyl alcohol (90% or higher) and a lint-free cloth to clean the cold plate and the CPU IHS.
When to Reapply Thermal Paste on an NZXT Kraken
While the pre-applied thermal paste on your NZXT Kraken is generally good for the cooler’s lifespan under normal use, there are scenarios where reapplying thermal paste is necessary:
- Removing the Cooler: If you remove the Kraken from the CPU, you must clean off the old thermal paste and apply fresh paste before reattaching it.
- Replacing the CPU: When upgrading your CPU, clean both the old CPU and the Kraken’s cold plate and apply new paste.
- Poor Cooling Performance: If you notice significantly higher CPU temperatures than expected, it could indicate dried-out or poorly applied thermal paste. Reapplication might improve cooling.
- Several Years of Use: Over time, thermal paste can dry out and lose its effectiveness. Consider reapplying every 2-3 years, especially if you push your CPU to its limits.
Applying Thermal Paste Correctly: A Crucial Step
If you need to apply your own thermal paste, here’s a general guide:
- Clean: Thoroughly clean both the CPU IHS and the Kraken’s cold plate with isopropyl alcohol and a lint-free cloth.
- Amount: Use a small, pea-sized amount of thermal paste in the center of the CPU IHS. Alternatively, some prefer the “X” method, applying thin lines diagonally across the CPU.
- Installation: Carefully mount the Kraken cooler onto the CPU, applying even pressure. The pressure will spread the thermal paste evenly.
- Secure: Secure the Kraken to the motherboard according to the manufacturer’s instructions.
Thermal Paste Options: What to Consider
While the pre-applied thermal paste is adequate, enthusiasts often opt for aftermarket options known for superior thermal conductivity. These include:
- Ceramic-based: Cost-effective and non-conductive.
- Metal-based: Offer excellent thermal conductivity but are electrically conductive, requiring careful application.
- Liquid metal: Provide the highest thermal conductivity but are also electrically conductive and can react with aluminum. Not recommended for beginners.
| Type of Thermal Paste | Thermal Conductivity (W/mK) | Electrical Conductivity | Advantages | Disadvantages |
|---|---|---|---|---|
| Ceramic-Based | 4-8 | Non-Conductive | Affordable, Easy to apply | Lower Thermal Conductivity |
| Metal-Based | 8-12 | Conductive | High Thermal Conductivity | Risk of short circuits, Requires careful application |
| Liquid Metal | 40-80 | Conductive | Extremely High Thermal Conductivity | Reacts with Aluminum, Electrically Conductive |
Common Mistakes to Avoid When Dealing with Thermal Paste
- Applying too much paste: Excess paste can spill over and potentially cause electrical shorts (especially with conductive pastes).
- Applying too little paste: Insufficient paste leads to poor contact and inefficient heat transfer.
- Using old or dried-out paste: This reduces the paste’s effectiveness and can even damage components.
- Not cleaning surfaces properly: Debris or old paste can hinder heat transfer.
- Ignoring instructions: Always refer to the manufacturer’s instructions for both the cooler and the thermal paste.
Troubleshooting Common Issues with NZXT Kraken Cooling
If you are experiencing high CPU temperatures despite having an NZXT Kraken liquid cooler, consider the following:
- Pump Failure: Check if the pump is running. You should hear a faint humming sound or feel a slight vibration. Monitor pump RPM in your BIOS or NZXT CAM software.
- Air Bubbles: Air bubbles in the loop can reduce cooling efficiency. Try tilting the case to dislodge air bubbles trapped in the pump or radiator.
- Fan Speed: Ensure the radiator fans are spinning and set to an appropriate speed. Increase fan speeds for better cooling under heavy loads.
- Incorrect Mounting: Double-check that the cooler is properly mounted and making good contact with the CPU IHS.
- Software Issues: Ensure NZXT CAM is properly installed and configured to monitor and control the Kraken’s pump and fan speeds.
FAQ:
