Overview of Thermalright Assassin X 120R SE V2 CPU Air Cooler
The Thermalright Assassin X 120R SE V2 CPU Air Cooler is a robust cooling solution priced at C$23.59. Designed for optimal thermal performance, it features advanced technology and a thoughtful design aimed at gamers and PC builders alike. The cooler employs 4×6mm heat pipes that utilise AGHP technology, ensuring effective heat dissipation and a service life of up to 20,000 hours. With a noise level of less than 25.6dB(A), it delivers quiet operation while maintaining efficient cooling, making it a suitable choice for medium-sized computer cases.
Overview of Thermalright LGA1700-BCF Black V2 CPU Retainer
The Thermalright LGA1700-BCF Black V2 CPU Retainer is a specialised accessory priced at C$8.99. Its primary function is to prevent CPU bending caused by larger coolers, particularly on Intel's LGA1700 socket. Made from an all-aluminium alloy, it combines durability with an appealing design. The retainer measures 54x70x6mm and includes an L-shaped screwdriver for easy installation. It supports various Intel CPU generations, ensuring compatibility with a wide range of motherboards and contributing to a seamless build experience.
Performance Comparison
When it comes to cooling performance, the Thermalright Assassin X 120R SE V2 is clearly the superior option. With a fan speed of 1550 RPM and an airflow rating of 66.17 CFM, it excels in heat dissipation, making it ideal for high-performance CPUs. In contrast, the Thermalright LGA1700-BCF Black V2 is not a cooling solution but rather a protective accessory, so it does not contribute directly to thermal performance. If cooling is your primary concern, the Assassin X 120R SE V2 stands out as the preferable choice.
Build Quality and Design
The build quality of both products is commendable, but they serve different purposes. The Thermalright Assassin X 120R SE V2 is constructed using industrial-grade materials, offering durability and long-term usage with its S-FDB bearings. The cooler is designed to fit in medium-sized cases, ensuring compatibility without obstructing RAM installation. On the other hand, the Thermalright LGA1700-BCF Black V2, made entirely from aluminium alloy, showcases a unique design intended to prevent CPU bending. While both products exhibit high-quality craftsmanship, they cater to distinct needs within a PC build.
Ease of Installation
Installation experience varies significantly between the two products. The Thermalright Assassin X 120R SE V2 features a straightforward installation process with provided mounting hardware and instructions. The cooler’s thoughtful design allows it to be set up without blocking RAM slots, simplifying the entire process. Conversely, the Thermalright LGA1700-BCF Black V2 is designed for easy installation, complete with an L-shaped screwdriver and clear instructions. While both products are user-friendly, the retainer's simplicity might appeal to those looking for quick and effective CPU protection.
Compatibility
Compatibility is essential when choosing cooling solutions and accessories. The Thermalright Assassin X 120R SE V2 supports a wide array of CPU sockets, including Intel's LGA1150 through LGA1700 and AMD's AM4/AM5. This broad compatibility enhances its appeal to users with diverse setups. The Thermalright LGA1700-BCF Black V2 is specifically designed for Intel’s LGA1700 socket and is compatible with 12th to 14th generation CPUs. While the retainer is limited to a specific socket type, it excels in preventing CPU bending within its designated application.
Value for Money
In terms of value, the Thermalright Assassin X 120R SE V2 offers substantial cooling performance for its price of C$23.59. Given its features, including PWM fans and advanced heat pipe technology, it provides excellent bang for your buck in the CPU cooling market. The Thermalright LGA1700-BCF Black V2, priced at C$8.99, is a cost-effective solution for those concerned about CPU bending, though it does not provide cooling capabilities. Depending on your needs, both products offer value, but the cooler delivers greater performance for a slightly higher investment.
Which should you buy?
Choosing between the Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Thermalright LGA1700-BCF Black V2 CPU Retainer ultimately depends on your specific needs.
