Pricing Comparison
When considering the price, the TR-Assassin X 120R SE V2 CPU Air Cooler is significantly more affordable at £14.49 compared to the ARCTIC Liquid Freezer III Pro 240, which retails for £56.49. This represents a price difference of £42.00, making the TR cooler a budget-friendly option for users looking for effective cooling without breaking the bank. However, while the TR cooler is economical, the higher price of the ARCTIC cooler may reflect additional features and performance capabilities that could justify the cost for serious gamers or overclockers.
Cooling Performance
In terms of cooling performance, the ARCTIC Liquid Freezer III Pro 240 is designed for superior heat dissipation, thanks in part to its dual 120mm fans and advanced mounting system. This model features the P12 PRO fan, which is touted to be more powerful and quieter than its predecessor and is particularly effective under high loads. On the other hand, the TR-Assassin X 120R SE V2, with its single 120mm fan, has a maximum airflow of 66.17 CFM at a noise level of ≤25.6 dB(A). While the TR cooler offers decent performance for general use, the ARCTIC model appears to be better suited for high-performance tasks.
Design and Aesthetics
The aesthetic appeal of a cooler can greatly influence a user's choice. The TR-Assassin X 120R SE V2 features a traditional heatsink design with static RGB lighting, which can add a touch of flair to any build. In contrast, the ARCTIC Liquid Freezer III Pro 240 opts for a more streamlined look with integrated cable management. Its PWM-controlled VRM fan not only enhances cooling efficiency but also contributes to a cleaner build by reducing visible cables. Users seeking a blend of functionality and modern aesthetics may lean towards the ARCTIC model.
Installation and Compatibility
Installation ease and compatibility are crucial factors to consider. The TR-Assassin X 120R SE V2 has a total height of only 148mm, making it compatible with most ATX cases while ensuring that RAM modules remain unobstructed. It supports a wide range of Intel and AMD socket types, including LGA1150 through LGA1700 and AM4/AM5. Conversely, the ARCTIC Liquid Freezer III Pro 240 features native offset mounting for both Intel and AMD, ensuring optimal heat transfer by aligning the cold plate with the CPU hotspot. This may require a bit more installation effort due to its AIO nature, but it promises enhanced efficiency.
Noise Levels
Noise levels can significantly impact the user experience, especially in quieter environments. The TR-Assassin X 120R SE V2 operates at a maximum noise level of ≤25.6 dB(A), making it a relatively quiet choice for those prioritising a low-noise system. On the other hand, while the ARCTIC Liquid Freezer III Pro 240 is designed to be quieter than previous models, specific noise levels are not provided. However, its P12 PRO fan is noted for being quieter under low speeds, which could imply it operates less noisily when under typical load conditions. Users who are sensitive to noise might find the TR cooler more appealing.
Durability and Longevity
Durability is essential for long-term performance, and both coolers are built with quality in mind. The ARCTIC Liquid Freezer III Pro 240 features an optimized contact frame that distributes pressure evenly, which may enhance the longevity of the CPU by promoting better heat dissipation. This focus on durability is complemented by its integrated VRM fan, which helps keep voltage converters cool. In contrast, the TR-Assassin X 120R SE V2, while constructed with sturdy aluminium and copper materials, does not mention specific durability enhancements like those present in the ARCTIC model. Users prioritising long-term reliability may favour the ARCTIC cooler.
User Experience and Support
User experience can hinge on support and community feedback. The ARCTIC brand is well-regarded for its customer service and support, which can be a significant advantage for users who may encounter issues during installation or operation. Additionally, the performance capabilities of the ARCTIC Liquid Freezer III Pro 240 are often highlighted in user reviews, especially in high-demand scenarios. The TR-Assassin X 120R SE V2 has garnered a reputation for being user-friendly and cost-effective, making it a great choice for newcomers to PC building. However, users seeking extensive support and community resources may find the ARCTIC model more beneficial.
Which should you buy?
Ultimately, the choice between the TR-Assassin X 120R SE V2 CPU Air Cooler and the ARCTIC Liquid Freezer III Pro 240 comes down to individual needs and preferences. If budget is your primary concern, the TR cooler's low price of £14.49 offers a compelling value for general use. However, for users seeking top-tier cooling performance, advanced features, and potential longevity, the ARCTIC Liquid Freezer III Pro 240's higher price of £56.49 may be worth the investment. Consider your cooling requirements, case compatibility, and whether you value aesthetics and noise levels when making your decision.
