Overview of the Products
The Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler stands out for its advanced cooling capabilities and aesthetic appeal, while the Intel i3/i5/i7 LGA115x CPU Heatsink offers a more budget-friendly option for basic cooling needs. The Thermalright cooler is priced at C$46.90, significantly higher than the Intel heatsink, which is available for C$19.99. This price difference reflects a variance in features and performance expectations between the two products.
Cooling Performance
The Thermalright Peerless Assassin 120 SE ARGB boasts a powerful performance with a thermal design power (TDP) rating of 120 to 245W, making it suitable for demanding processors. It features six heat pipes and two PWM fans that deliver a maximum airflow of 66.17 CFM while maintaining a noise level of less than 25.6 dB(A). In contrast, the Intel heatsink supports a maximum TDP of 65W, which may limit its effectiveness for higher-tier processors. This makes the Thermalright cooler a better choice for gamers or users with high-performance CPUs.
Build Quality and Design
In terms of build quality, the Thermalright Peerless Assassin 120 SE ARGB is constructed with aluminum and features a full electroplating reflow welding process. It weighs 0.97 kg (2.1 lb), indicating a robust design that can handle rigorous usage. The Intel heatsink, while made from aluminum, does not specify its weight, but it is designed for easier installation with pre-applied thermal paste and tool-free push pin installation. The Thermalright cooler also comes with ARGB lighting, providing a visually appealing addition to gaming rigs, while the Intel model lacks such aesthetic features.
Compatibility
The Thermalright cooler offers extensive compatibility with both Intel and AMD platforms, supporting sockets including LGA 115X, 1200, and 1700, as well as AMD’s AM4. This versatility makes it a more future-proof option for users looking to upgrade their systems. On the other hand, the Intel heatsink is specifically designed for Intel i3, i5, and i7 processors with a focus on LGA 115x sockets. While it is compatible with a range of Intel CPUs, its limited socket support restricts its usability for those who may want to switch to AMD platforms in the future.
Installation Process
The installation process for the Thermalright Peerless Assassin 120 SE ARGB is simplified with included metal fasteners that ensure a secure fit on various CPU sockets. This cooler’s design allows for unrestricted RAM installation, which is a crucial feature for users with larger memory modules. Conversely, the Intel heatsink offers an easy and tool-free installation process with its push pin system. While both coolers aim to make installation straightforward, the Thermalright model’s flexibility in RAM clearance can be a decisive factor for some users.
Noise Levels
When it comes to noise levels, the Thermalright Peerless Assassin 120 SE ARGB operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a dual-fan cooler. This makes it suitable for users who prioritize a silent operation during intense gaming or work sessions. In comparison, the Intel heatsink does not specify its noise level, but as a lower-end solution, it is likely to operate louder under load due to its single-fan design. Therefore, if a quieter cooling solution is a priority, the Thermalright cooler is the preferred choice.
Aesthetic Appeal
The Thermalright Peerless Assassin 120 SE ARGB not only excels in performance but also in aesthetics, featuring vibrant ARGB lighting that can enhance the visual setup of any gaming rig. This cooler is designed to be a statement piece, appealing to users who value the look of their components. In contrast, the Intel heatsink is more utilitarian in design, focusing on function over form. While it effectively cools the CPU, it lacks any stylish features that might attract users looking to match their cooler with other RGB components.
Which should you buy?
The decision between the Thermalright Peerless Assassin 120 SE ARGB and the Intel i3/i5/i7 LGA115x CPU Heatsink ultimately depends on your specific needs and budget. If you require superior cooling performance, extensive compatibility, and enhanced aesthetics, the Thermalright cooler at C$46.90 is undoubtedly the better choice. However, if you are looking for a cost-effective solution that adequately cools lower TDP processors, the Intel heatsink priced at C$19.99 may suffice. For budget-conscious users or those with basic computing needs, the Intel model is a practical option, but serious gamers and high-performance users will benefit greatly from the advanced features and capabilities of the Thermalright Peerless Assassin 120 SE ARGB.
