Laptops are designed to balance portability and performance, but this often comes at a cost: overheating. While most laptops come with built-in cooling systems, they may not always be sufficient for users engaged in high-performance tasks like gaming, video editing, or running resource-intensive applications. Over time, overheating can lead to performance degradation, hardware damage, and reduced device lifespan.

For those experiencing persistent overheating, upgrading to an aftermarket internal laptop cooler can be an effective solution. Unlike external cooling pads, aftermarket internal coolers work directly with the laptop’s internal components, providing targeted cooling for CPUs, GPUs, and other heat-generating parts.

In this article, we'll explore some of the best aftermarket internal laptop coolers currently available. We’ll also discuss how these products work, the benefits they offer, and what to consider before upgrading your laptop's cooling system.

Why Consider an Aftermarket Internal Cooler?

Before diving into the specific products, it's important to understand why aftermarket internal cooling solutions are so beneficial.

Laptops typically come with built-in fans and heat sinks that work together to dissipate heat. However, the compact design of laptops limits airflow, causing temperatures to rise quickly, especially during heavy use. Aftermarket internal coolers help by offering better thermal conductivity and more efficient heat dissipation. These coolers usually consist of improved heat sinks, fans, or thermal pads that work in tandem with the existing cooling system to reduce the laptop's internal temperature.

For gamers, video editors, or professionals using demanding software, upgrading the internal cooling system can lead to better performance, reduced thermal throttling, and extended hardware life. Here are some of the best options available today.

1. Cooler Master MasterGel Maker Nano

The Cooler Master MasterGel Maker Nano is one of the top thermal paste solutions for users looking to improve the efficiency of their laptop's cooling system. Thermal paste is crucial in ensuring optimal heat transfer between the CPU/GPU and the heat sink. Over time, factory-applied thermal paste can dry out, leading to less effective cooling and higher temperatures.

This thermal compound uses nano-diamond particles that offer superior thermal conductivity compared to standard compounds. The MasterGel Maker Nano has a thermal conductivity rating of 11 W/mK, making it one of the most efficient thermal pastes available on the market.

Reapplying high-quality thermal paste like the Cooler Master MasterGel Maker Nano can lead to significant temperature reductions, especially in older laptops where the original paste has degraded. It’s an affordable and easy-to-apply option for users who want to improve cooling performance without replacing hardware.

2. Noctua NT-H2 Thermal Compound

Another excellent thermal paste option is the Noctua NT-H2. Known for its long-lasting performance and ease of application, the NT-H2 is ideal for both gaming laptops and ultrabooks. With a thermal conductivity of 8.9 W/mK, it provides a solid balance between performance and affordability.

One of the standout features of Noctua’s thermal compounds is their longevity. Unlike some thermal pastes that need to be reapplied every few months, the NT-H2 can last for years without significant performance degradation. This makes it a great choice for users who want an effective, long-term cooling solution.

Additionally, Noctua includes cleaning wipes with their thermal compound, making it easy to remove old paste before applying the new one. This can further improve heat dissipation and ensure a clean application.

3. Thermaltake Engine 27 1U Low-Profile CPU Cooler

For users looking for an actual hardware upgrade, the Thermaltake Engine 27 1U Low-Profile CPU Cooler is a high-performance cooling fan that fits most laptop CPUs. It’s designed to be extremely thin (just 27mm in height), making it a perfect option for laptops with limited internal space.

This cooler uses a unique 60mm fan with an all-metal design, offering enhanced durability and better heat dissipation than traditional plastic fans. The Engine 27 also comes with a built-in heat sink to maximize airflow around the CPU, helping to lower temperatures during heavy use.

It’s a popular choice for gaming laptops or workstations that need additional cooling without sacrificing too much space. However, installation can be a bit tricky for users unfamiliar with laptop disassembly, so professional help might be required for some models.

4. Arctic MX-4 Thermal Paste

If you’re looking for a budget-friendly option that still delivers impressive cooling results, the Arctic MX-4 Thermal Paste is a solid choice. It has a thermal conductivity of 8.5 W/mK, making it comparable to some higher-end thermal compounds, but at a much lower price point.

The Arctic MX-4 is also highly durable and non-electrically conductive, which means there’s no risk of damaging components if applied incorrectly. It’s an ideal choice for users who want to reapply thermal paste themselves and improve their laptop’s cooling performance without spending a lot of money.

The MX-4 is particularly popular among gamers and overclockers for its ability to reduce CPU and GPU temperatures under heavy loads. Regular users can also benefit from reduced fan noise and better overall laptop performance after applying this thermal paste.

5. Phanteks PH-NDC Thermal Compound

The Phanteks PH-NDC Thermal Compound is another high-quality thermal paste designed to improve the thermal conductivity between your laptop’s processor and heat sink. It offers excellent heat dissipation and is a great choice for users who experience high temperatures during extended gaming sessions.

Additionally, this compound is easy to apply and clean, making it a convenient option for users who want to improve their laptop’s cooling without any hassle. It’s a versatile thermal compound that delivers great results across a wide range of laptop models.

6. Thermal Grizzly Conductonaut Liquid Metal

For users who need extreme cooling performance, Thermal Grizzly Conductonaut is one of the best liquid metal thermal pastes available. Unlike traditional thermal pastes, which are typically made from silicone or ceramic, Conductonaut uses a metal-based formula with significantly higher thermal conductivity (73 W/mK).

Liquid metal compounds are known for their superior cooling capabilities, especially in high-performance gaming laptops and workstations. The Conductonaut can drastically reduce temperatures by improving the heat transfer between the CPU/GPU and heat sink. This is particularly useful for users who engage in overclocking or run demanding applications for extended periods.

However, applying liquid metal is more challenging than traditional pastes. It’s highly conductive and requires careful application to avoid damaging sensitive components. If used correctly, though, it can deliver unparalleled cooling results.
