Noctua NH-D15 vs Thermalright AXP90 X47 Full Low Profile CPU Cooler

Introduction to CPU Coolers

When it comes to maintaining optimal temperatures in your PC, choosing the right CPU cooler is essential. In this comparison, we’ll take a closer look at the Noctua NH-D15 and the Thermalright AXP90 X47 Full Low Profile CPU Cooler. The Noctua NH-D15 is renowned for its exceptional cooling performance and quiet operation, while the Thermalright AXP90 X47 offers a compact design ideal for smaller builds. With prices at C$149.95 and C$43.39 respectively, both coolers cater to different needs and budgets.

Cooling Performance

The Noctua NH-D15 boasts a state-of-the-art dual-tower design featuring six heatpipes and two 140mm fans, providing class-leading cooling performance ideal for overclocking. Its two NF-A15 fans deliver efficient airflow and low noise levels, making it a top choice for users seeking to push their systems to the limit. On the other hand, the Thermalright AXP90 X47 utilises AGHP technology with four 6mm heat pipes, which enhances cooling efficiency by addressing the inverse gravity effect. While it may not match the raw performance of the NH-D15, its design allows for adequate cooling in compact builds, particularly with its 92mm PWM fan.

Design and Size

The Noctua NH-D15 is a larger cooler, featuring a dual-tower layout that measures significantly more than the AXP90 X47. This cooler’s size not only contributes to its impressive cooling capabilities but also makes it somewhat challenging to fit into smaller cases. In contrast, the Thermalright AXP90 X47 is designed with a height of just 47mm, making it perfect for HTPCs and ITX builds where space is limited. Its compact design ensures compatibility without memory clearance issues, appealing to users with smaller form factors.

Noise Levels

Noise levels are a crucial consideration for many PC builders, especially those looking to create a near-silent system. The Noctua NH-D15 is equipped with advanced Low-Noise Adaptors, allowing for automatic speed control that maintains quiet operation even under load. This cooler is renowned for its whisper-quiet performance. Meanwhile, the Thermalright AXP90 X47 operates at a maximum noise level of 22.4 dB(A), which is commendable for its size but slightly louder than the NH-D15. Users prioritising silence may favour Noctua's offering, while those needing a compact cooler might find the AXP90 X47 sufficient.

Installation and Compatibility

Ease of installation is another important factor when choosing a CPU cooler. The Noctua NH-D15 comes with the SecuFirm2 mounting system, which simplifies the installation process on various Intel and AMD sockets, including LGA1700, LGA1200, AM5, and AM4. This versatility ensures that users can confidently install the cooler on a range of systems. The Thermalright AXP90 X47 also scores well in this regard, supporting multiple Intel and AMD sockets and providing corresponding mounting fasteners. However, its installation process will be simpler in smaller cases due to its low profile.

Thermal Paste and Accessories

Both coolers come with high-quality thermal paste to ensure optimal heat transfer from the CPU. The Noctua NH-D15 includes NT-H1 thermal paste, which is well-regarded in the industry and contributes to its efficient cooling performance. The Thermalright AXP90 X47 also provides thermal paste that enhances its cooling capabilities, although specific details about its performance are less highlighted. This inclusion in both products ensures users have everything they need for an effective installation right out of the box.

Brand Reputation and Warranty

Noctua is renowned for its high-quality products and has received over 250 awards and recommendations from leading hardware websites and magazines. This reputation is backed by a six-year manufacturer's warranty, offering peace of mind for buyers. Thermalright, with over 20 years of experience in the market, is also a respected brand, especially in the player market. While it may not have the same level of recognition as Noctua, Thermalright’s focus on R&D in cooling technology reflects its commitment to quality. However, it’s worth noting that the AXP90 X47 does not come with a specified warranty period, which may influence buyer confidence.

Price Comparison

Price is a significant factor when choosing between these two coolers. The Noctua NH-D15 is priced at C$149.95, reflecting its premium quality and performance capabilities. In contrast, the Thermalright AXP90 X47 is much more budget-friendly at C$43.39. This steep price difference means that while the NH-D15 offers superior performance and build quality, the AXP90 X47 provides an accessible option for those with tighter budgets or specific space constraints.

Which should you buy?

Deciding between the Noctua NH-D15 and the Thermalright AXP90 X47 ultimately comes down to your specific needs. If you’re looking for top-tier cooling performance, quiet operation, and are willing to invest in a larger cooler, the Noctua NH-D15 is the clear choice. However, if you require a compact solution for a small form factor build and prefer to keep costs low, the Thermalright AXP90 X47 offers solid performance at a fraction of the price. Each cooler caters to different use cases, making your choice dependent on your build requirements and budget constraints.
