Price Comparison
When it comes to pricing, the Thermalright Assassin X120 SE ARGB CPU Air Cooler is significantly more affordable than the ARCTIC Freezer 36. The Thermalright model is priced at £16.29, while the ARCTIC Freezer 36 comes in at £22.99. This price difference of £6.70 may appeal to budget-conscious consumers looking for effective cooling solutions without breaking the bank. While both products target similar performance levels, the cost can be a crucial deciding factor for many users.
Cooling Performance
In terms of cooling performance, both the ARCTIC Freezer 36 and the Thermalright Assassin X120 SE offer effective solutions, but they employ different technologies. The ARCTIC Freezer 36 is designed with four offset heat pipes that facilitate rapid heat transfer to the heat sink, maximising cooling efficiency. This single-tower cooler benefits from pressure-optimised 120 mm fans, which effectively dissipate heat. On the other hand, the Thermalright Assassin X120 SE features four 6 mm heat pipes that utilise AGHP technology, designed to counteract inverse gravity effects. This innovative approach also ensures efficient cooling across various orientations, showcasing the unique strengths of both products.
Installation Process
The installation process differs between the two coolers, which can impact user experience. The ARCTIC Freezer 36 employs an innovative Click-installation system, making it easier to install or replace fans while ensuring compatibility with most 120 mm fans. However, for AMD users, it requires the original mounting screws from the motherboard, which may pose a challenge if they are missing. Conversely, the Thermalright Assassin X120 SE is equipped with metal fasteners for both Intel and AMD platforms, providing a straightforward installation process. Its compact dimensions of 120 mm x 71 mm x 148 mm allow it to fit into medium-sized computer cases seamlessly.
Noise Levels
Noise levels are a critical consideration for many users, especially those building a quiet workstation or gaming rig. The Thermalright Assassin X120 SE is designed with low noise levels in mind, operating at a maximum of 25.6 dB(A), which is commendably quiet for a cooler of its size. In contrast, while the ARCTIC Freezer 36 doesn’t specify its noise levels, the focus on efficient airflow suggests it may be competitive in this area. However, without explicit figures, users seeking a silent operation may lean towards the proven lower noise output of the Thermalright model.
Aesthetic Appeal
Aesthetic appeal can play a significant role in a consumer's choice, particularly for those who value the appearance of their builds. The Thermalright Assassin X120 SE features colourful and gorgeous ARGB light effects that can enhance the visual appeal of a gaming setup or workstation. This can be a substantial draw for users who appreciate RGB lighting and want to customise their PC’s look. On the other hand, the ARCTIC Freezer 36 focuses on functionality over flair, with a design prioritising cooling efficiency rather than RGB features. Depending on personal preference, this could be a significant factor in the decision-making process.
Brand Reputation
Brand reputation can influence consumer choices significantly. ARCTIC is well-regarded for its high-performance cooling solutions, particularly in the enthusiast community. The Freezer 36 has a solid reputation for delivering reliable cooling for high-end CPUs. Meanwhile, Thermalright, with over 20 years of experience in the market, has carved out a niche for itself in both domestic and international markets. Its focus on research and development has resulted in a range of competitive products, including the Assassin X120 SE. While both brands boast positive reputations, individual preferences may sway users toward one over the other based on past experiences or brand loyalty.
Compatibility
Compatibility is another important factor when choosing a CPU cooler. The ARCTIC Freezer 36 supports Intel LGA1851 and LGA1700 sockets and requires original AMD mounting screws, which may limit its appeal if users do not have these screws available. On the other hand, the Thermalright Assassin X120 SE is compatible with a broader range of sockets, including Intel’s LGA1150 through LGA1700 and AMD’s AM4 and AM5. This versatility makes the Thermalright model a more accommodating option for users with different CPU configurations, further enhancing its appeal.
Which should you buy?
Ultimately, the choice between the ARCTIC Freezer 36 and the Thermalright Assassin X120 SE comes down to individual needs and preferences. If you prioritise performance and brand reputation, the ARCTIC Freezer 36 may be the better choice, especially for high-end CPUs. However, if you are looking for a budget-friendly option that offers great cooling efficiency, low noise levels, and appealing aesthetics with RGB lighting, the Thermalright Assassin X120 SE stands out as an excellent option. Consider your specific requirements in terms of price, performance, installation, and compatibility to make the best decision for your setup.
