As a streamlined and accessible version of the original LS520, this AIO liquid cooler is designed to provide exceptional thermal management for modern CPUs, all while offering a brilliant ARGB lighting experience.¹ With a focus on the keyphrase DEEPCOOL LS520, this article will dive into the technical details and myriad benefits of this highly sought-after cooler.

Technical Details: The Engine of Performance

The core of any great cooler is its ability to efficiently transfer and dissipate heat. The DEEPCOOL LS520 SE is built with a host of technical features that ensure it meets the demands of even the most powerful processors.²

4th Generation High-Performance Pump

At the heart of the DEEPCOOL LS520 SE is its advanced 4th Generation water pump.³ This pump is the result of years of engineering and innovation, designed to maximize cooling performance while maintaining a low-noise profile.⁴

• Powerful Three-Phase Drive Motor: The pump operates with a powerful three-phase brushless motor that can reach a speed of up to 3100 RPM.⁵ This high rotational speed ensures that coolant circulates rapidly and consistently through the loop, quickly carrying heat away from the CPU.⁶

   

• Optimized Microchannel Design: The pump’s cold plate, made of pure copper, features an improved microchannel design.⁷ These fine channels are engineered to maximize the surface area for heat exchange between the copper base and the coolant, dramatically improving thermal efficiency.⁸

   

• Thick Solid Copper Cold Plate: The CPU’s heat is first absorbed by a thick, solid copper cold plate.⁹ The superior thermal conductivity of copper ensures that heat is drawn from the CPU’s integrated heat spreader (IHS) and transferred to the liquid coolant as efficiently as possible.

   

• Patented Anti-Leak Technology: DeepCool has integrated its exclusive Anti-Leak Technology into the cooler.¹⁰ This system features an internal pressure-balancing valve that automatically purges excess pressure as the coolant temperature rises.¹¹ This proactive measure significantly reduces the risk of leaks, providing peace of mind and extending the cooler’s lifespan.¹²

   

High-Efficiency 240mm Radiator

The DEEPCOOL LS520 SE utilizes a 240mm aluminum radiator with dimensions of 282 x 120 x 27 mm.¹³ This radiator provides a substantial surface area for heat dissipation.¹⁴ The dense fin array is specifically optimized to work with the included fans, ensuring that the liquid coolant is cooled down as effectively as possible before it returns to the CPU block. The 410mm-long tubing is made of high-quality materials, offering flexibility for a clean installation in a variety of PC cases.¹⁵

Hydro Bearing Fans with ARGB Lighting

The DEEPCOOL LS520 SE comes with two 120mm ARGB PWM fans that are purpose-built for high-static pressure applications like radiators.¹⁶

• High Static Pressure and Airflow: These fans are capable of generating a high static pressure of up to 3.27 mmAq and an impressive airflow of 85.85 CFM.¹⁷ This potent combination allows them to push a significant volume of air through the radiator’s dense fins, ensuring rapid heat transfer and superior cooling.

   

• Hydro Bearing: The fans use a reliable Hydro Bearing, which is known for its quiet operation and durability.¹⁸ The low-friction design of the bearing helps to reduce noise and vibration, contributing to a more silent computing experience, even under heavy load.¹⁹ The fans have an operational lifespan of approximately 50,000 hours.²⁰

   

• Wide PWM Speed Range: The fan speeds are dynamically controlled by PWM (Pulse Width Modulation), with a range of 500 to 2250 RPM.²¹ This allows you to create a fan curve that perfectly balances cooling performance and noise levels. For noise-sensitive users, a low-speed adapter is included to limit the maximum speed and reduce noise output by up to 10 dB.²²

   

Benefits of Use: Why Choose the DEEPCOOL LS520 SE?

The DEEPCOOL LS520 SE isn’t just a collection of impressive technical specs; it’s a product designed with the end-user in mind, offering a range of tangible benefits that enhance the PC building and usage experience.

Exceptional Cooling for Demanding Processors

With a TDP (Thermal Design Power) rating of up to 280W, the DEEPCOOL LS520 SE is a beast when it comes to cooling. This makes it an ideal choice for high-end gaming CPUs and workstations that require a robust cooling solution to prevent thermal throttling and ensure stable performance during demanding tasks like gaming, video editing, and rendering.

Striking ARGB Aesthetics

Aesthetics are a crucial component of modern PC building, and the DEEPCOOL LS520 SE excels in this area.²³

• Radiant Reflections: The CPU water block features a unique infinity mirror design on its top cover.²⁴ This design creates a mesmerizing visual effect of two light loops extending into infinity, providing a stunning centerpiece for your PC build.

   

• Addressable RGB (ARGB) Lighting: Both the pump and the two fans are equipped with vibrant ARGB LEDs.²⁵ The lighting can be easily controlled and synchronized with your motherboard’s software, including popular platforms like ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light, and ASRock Polychrome.²⁶ This allows for full customization of colors, patterns, and effects, enabling you to create a truly personalized lighting scheme.

   

Simple Installation and Broad Compatibility

The DEEPCOOL LS520 SE is designed for a hassle-free installation process.²⁷ The included mounting hardware is sturdy and easy to work with, ensuring a secure and proper fit on a wide range of CPU sockets.²⁸ It offers broad compatibility with the latest Intel and AMD platforms, including LGA 1700, LGA 1200, AM5, and AM4, as well as previous generations.²⁹ The pre-applied thermal paste on the cold plate is a thoughtful addition that simplifies the installation even further, getting you up and running quickly.

Quiet and Efficient Operation

Noise can be a significant issue for high-performance components, but the DEEPCOOL LS520 SE is engineered to be as quiet as possible.³⁰ The low-noise pump operates at just 19 dB(A), while the fans, even at their maximum speed, are capped at ≤32.9 dB(A).³¹ For users who prioritize silence, the included low-speed adapter is a game-changer, allowing for a significant reduction in fan noise without a drastic drop in cooling performance.³² This makes the cooler a great choice for both silent home theater PCs and high-performance gaming rigs.
