Overview of Thermalright Peerless Assassin 120 SE and MSI MAG CORELIQUID A13

The Thermalright Peerless Assassin 120 SE is a CPU air cooler priced at £26.90, while the MSI MAG CORELIQUID A13 is a liquid cooler retailing for £53.99. Both products aim to provide efficient cooling solutions but cater to different preferences and needs in the gaming and computing community.

Thermalright has a long-standing reputation in the market with over 20 years of experience, focusing on computer accessories and cooling solutions. On the other hand, MSI's CORELIQUID series boasts advanced cooling technology, featuring an enlarged copper cold plate and high-performance pump that enhances heat dissipation. This initial price difference sets the stage for further exploration of their respective features.

Cooling Performance

In terms of cooling performance, the MSI MAG CORELIQUID A13 takes the lead with its advanced design. It features an enlarged copper cold plate and more internal micro-channels that enhance the surface-area-to-volume ratio, optimising heat dissipation. The high-performance pump operates at speeds up to 3800 RPM, ensuring effective cooling even under heavy loads.

Conversely, the Thermalright Peerless Assassin 120 SE utilises a double tower design and six heat pipes, which help counteract the inverse gravity effect. Its dual PWM fans can spin at 1550 RPM, offering a maximum airflow of 66.17 CFM. While it provides adequate cooling, it may not match the advanced cooling dynamics of the MSI counterpart, especially for users pushing their systems to the limits.

Noise Levels

Noise levels are crucial for users seeking a quieter operation during intense gaming or productivity sessions. The Thermalright Peerless Assassin 120 SE operates at a noise level of less than 25.6 dB(A), which is relatively quiet, making it suitable for silent builds.

In contrast, the MSI MAG CORELIQUID A13 operates at a moderate noise level of 31.1 dBA. This is due to its powerful fans, which, while providing high static pressure and airflow, may introduce more sound compared to the Thermalright unit. Users prioritising a quiet environment may prefer the Thermalright cooler for its superior noise performance.

Installation and Compatibility

Installation is an essential factor when choosing a CPU cooler. The Thermalright Peerless Assassin 120 SE is compatible with a wide range of Intel and AMD sockets, including Intel LGA 1150 to 1700 and AMD AM4/AM5. It comes equipped with metal fasteners for a straightforward installation process.

The MSI MAG CORELIQUID A13 is designed for ease of installation as well, with pre-installed fans that reduce assembly time. However, it is vital to ensure compatibility with the motherboard, as liquid coolers like the A13 require specific mounting configurations. Both products offer robust compatibility, but the simple installation of the Thermalright may appeal more to novice builders.

Aesthetics and Design

Aesthetics can play a significant role in a user's choice of cooler. The Thermalright Peerless Assassin 120 SE features a functional design prioritising performance over flashy aesthetics, making it a versatile option for various builds.

In contrast, the MSI MAG CORELIQUID A13 boasts a more visually striking design with its translucent fan blades accentuating ARGB illumination. The frosted exterior finish and steel-gray painted cover contribute to a sophisticated look, appealing to gamers who value visual presentation alongside performance. Users looking for an eye-catching setup may favour the MSI cooler for its aesthetic appeal.

Build Quality and Materials

Build quality is paramount for the longevity of cooling solutions. The Thermalright Peerless Assassin 120 SE is constructed with a robust aluminium heat sink and features six copper heat pipes for heat transfer efficiency. The use of durable materials ensures that it can withstand prolonged use without degradation.

The MSI MAG CORELIQUID A13 also employs high-quality materials, including a high-performance pump with ceramic bearings for improved durability. Its construction is designed to handle the rigours of cooling effectively, but the reliance on liquid introduces a different set of considerations regarding potential leaks. Both products exhibit solid build quality, but users may prefer Thermalright's traditional air-cooling method for its reliability.

Price Comparison

Price is a significant factor when choosing between the two coolers. The Thermalright Peerless Assassin 120 SE is priced at £26.90, making it a budget-friendly option for those seeking effective CPU cooling without breaking the bank. It offers excellent value for its performance level.

In contrast, the MSI MAG CORELIQUID A13 is priced at £53.99, reflecting its advanced technology and performance capabilities. While it offers superior cooling and aesthetics, the higher price point may deter budget-conscious users. The decision may depend on whether one values enhanced performance and aesthetics enough to justify the price difference.

User Experience and Reviews

User experience can provide insights into the real-world performance of these coolers. The Thermalright Peerless Assassin 120 SE is often praised for its quiet operation and efficient cooling, making it a favourite among users who prioritise noise reduction.

The MSI MAG CORELIQUID A13 receives accolades for its impressive cooling performance and aesthetic design, although some users report that the noise at higher RPMs can be noticeable. Both products have their loyal followings, catering to different preferences and needs within the gaming community.

Which should you buy?

Ultimately, the decision between the Thermalright Peerless Assassin 120 SE and the MSI MAG CORELIQUID A13 boils down to personal preferences and specific use cases. If you are seeking an economical option with quiet operation and good cooling performance, the Thermalright cooler is an excellent choice. However, if you desire advanced cooling technology, striking aesthetics, and are willing to invest more, the MSI liquid cooler is worth considering. Each product has its strengths, appealing to different segments of the market.
