Dimension comparison
Overview of the Kalemax CPU Cooler
The Kalemax CPU Cooler is priced at $29.99, offering a dual-tower design with impressive cooling performance. It features six 6mm heat pipes and dual 120mm ARGB PWM fans that can reach speeds of 2000 RPM, making it suitable for high-performance builds. Its maximum thermal design power (TDP) is rated at 265W, which provides ample cooling for demanding CPUs.
The cooler is designed for compatibility with a wide range of Intel and AMD sockets, including Intel LGA 115X/1200/1700/1851 and AMD AM4/AM5. The ARGB lighting enhances the aesthetic appeal, with up to 16 lighting modes available. This cooler not only prioritizes performance but also looks great in any setup.
Overview of the Thermalright Assassin King 120 SE
The Thermalright Assassin King 120 SE is a more budget-friendly option at $19.82, making it approximately 17% cheaper than the Kalemax. This cooler employs a single tower design with five heat pipes and features a TL-C12CW-S PWM fan that operates at a maximum speed of 1550 RPM, providing a maximum airflow of 66.17 CFM.
With a height of 148mm, it is suitable for medium-sized cases and supports similar socket compatibility as the Kalemax, including Intel LGA 115X/1200/1700/1851 and AMD AM4. The cooler also boasts ARGB lighting, offering a stylish look without compromising on cooling efficiency.
Cooling Performance Comparison
When it comes to cooling performance, the Kalemax CPU Cooler takes the lead with its dual-tower design and higher maximum fan speed of 2000 RPM. This setup enables it to handle a TDP of 265W, making it a strong contender for high-end CPUs that generate significant heat.
In contrast, the Thermalright Assassin King 120 SE operates at a maximum fan speed of 1550 RPM and supports a lower airflow of 66.17 CFM. While it is efficient for mid-range CPUs, it may not provide sufficient cooling for more demanding applications compared to the Kalemax. This difference in cooling capability is vital for users looking to push their CPUs to the limit during gaming or heavy workloads.
Noise Levels and Efficiency
The Kalemax CPU Cooler has a noise level of up to 27.8 dBA, while the Thermalright Assassin King 120 SE operates at a quieter maximum of 25.6 dBA. This means that the Thermalright cooler is better suited for users who prioritize a silent operation in their builds.
However, the Kalemax compensates for its slightly higher noise level with superior cooling performance, making it ideal for users who are willing to tolerate a bit more noise for better thermal management. The balance between noise and performance will depend on individual user needs—whether one prefers quieter operation or enhanced cooling capabilities.
Installation and Compatibility
Both the Kalemax and Thermalright coolers offer wide compatibility with various Intel and AMD sockets. The Kalemax provides thorough mounting options for Intel LGA 115X/1200/1700/1851 and AMD AM4/AM5, ensuring a secure fit across different platforms.
Similarly, the Thermalright Assassin King 120 SE also supports the same Intel and AMD sockets, making it a versatile option for many setups. Installation for both coolers is straightforward due to their included metal fasteners. Users can expect a hassle-free experience when fitting either cooler to their systems.
Aesthetic Appeal
Aesthetically, both coolers are equipped with ARGB lighting, which enhances the visual appeal of any rig. The Kalemax cooler features specially treated fan blades that diffuse light for a uniform effect, offering up to 16 lighting modes that can be synchronized with other ARGB components.
The Thermalright Assassin King 120 SE also showcases colorful ARGB effects, making it a visually attractive addition to any gaming setup. The choice between the two may come down to personal preference regarding their lighting effects and overall design, as both units are designed to complement modern gaming builds.
Value for Money
In terms of value, the Thermalright Assassin King 120 SE is the more economical choice at $19.82, making it an attractive option for budget-conscious consumers. However, the Kalemax CPU Cooler, priced at $29.99, offers significantly better cooling performance, especially for users with high-end components requiring robust thermal management.
While both coolers provide good compatibility and aesthetic appeal, the decision ultimately hinges on whether users prioritize cooling efficiency or budget. For those looking for the best performance, the Kalemax justifies its higher price with superior cooling capabilities.
Which should you buy?
In conclusion, choosing between the Kalemax CPU Cooler and the Thermalright Assassin King 120 SE boils down to individual needs and budget. The Kalemax is the clear winner for users seeking high-performance cooling with its dual-tower design and higher RPM, making it ideal for demanding CPUs. However, if budget is a primary concern and the user is working with mid-range components, the Thermalright Assassin King 120 SE offers significant savings while still providing decent cooling performance. Ultimately, both coolers have their strengths, catering to different segments of the market effectively.
