Price Comparison

When it comes to pricing, the Thermalright Assassin X 120 SE is significantly more affordable than the Thermalright Frozen Notte 240 Black ARGB. The Assassin X 120 SE is priced at C$25.59, while the Frozen Notte 240 commands a higher price of C$62.90. This price difference of C$37.31 makes the Assassin X 120 SE an attractive option for budget-conscious consumers looking for effective cooling solutions without breaking the bank.

Cooling Performance

The Thermalright Frozen Notte 240 Black ARGB is designed for superior cooling performance compared to the Assassin X 120 SE. With a high-performance cold head capable of speeds up to 5300 RPM, it promises exceptional CPU cooling. In contrast, the Assassin X 120 SE features a maximum fan speed of 1550 RPM. While both coolers serve their purpose, the Frozen Notte’s water cooling technology provides lower resistance and improved cooling efficiency, making it suitable for high-performance builds.

Design and Aesthetics

In terms of design, the Thermalright Frozen Notte 240 Black ARGB stands out with its integrated ARGB lighting that can sync with motherboard RGB headers. This feature allows users to create dazzling light displays while enjoying effective cooling. The Assassin X 120 SE, while functional, lacks this advanced lighting technology and is primarily focused on straightforward cooling performance. For those who appreciate aesthetics alongside functionality, the Frozen Notte offers a more visually appealing choice.

Noise Levels

Noise levels are an important consideration in cooling solutions. The Thermalright Assassin X 120 SE operates at a noise level of ≤25.6 dB(A), making it one of the quieter options available. In comparison, the Frozen Notte's PWM fans operate at ≤27.7 DBA. While the difference in noise levels is slight, the Assassin X 120 SE may be the better choice for users who prioritise a quiet computing environment, particularly in smaller cases or during extended use.

Compatibility

Both coolers are compatible with a range of Intel and AMD sockets, making them versatile options for various builds. The Frozen Notte supports a wider range of Intel sockets, including LGA 1700 and 2066, as well as multiple AMD platforms such as AM5 and AM4. The Assassin X 120 SE, while still broadly compatible, supports fewer Intel sockets, specifically the 115X and 1200 series. If you have a high-end Intel build, the Frozen Notte may offer better compatibility and future-proofing.

Installation and Ease of Use

Installation can significantly impact the user experience, and here, the Thermalright products provide differing levels of convenience. The Frozen Notte features a dual platform full metal black buckle for easy installation, while the Assassin X 120 SE comes with metal fasteners designed for straightforward mounting. However, the Frozen Notte's extensive compatibility might require more careful consideration of installation space, especially in cases narrower than 250mm. For users looking for simplicity, the compact design of the Assassin X 120 SE could be advantageous.

Longevity and Durability

The longevity of a cooler can be linked to its design and components. The Thermalright Frozen Notte 240 employs high polymer woven protective water pipes and a high-quality copper base, promising long-term durability. This is contrasted by the Assassin X 120 SE, which utilises S-FDB bearings for a service life of up to 20,000 hours. While both products are built to last, the materials and construction of the Frozen Notte may offer a slight edge in terms of long-term performance, especially in demanding applications.

Which should you buy?

Choosing between the Thermalright Frozen Notte 240 Black ARGB and the Thermalright Assassin X 120 SE ultimately depends on your specific needs and budget. If you're seeking top-tier cooling performance, aesthetic appeal, and are willing to invest more, the Frozen Notte 240 is the superior option. However, if you're looking for a budget-friendly, quieter cooler that still provides solid performance for moderate builds, the Assassin X 120 SE is an excellent choice. Consider your priorities: performance and aesthetics versus cost-effectiveness and quiet operation.
