DeepCool LS520 SE Digital

Manufacturer: DeepCool

The DeepCool LS520 SE Digital is a 240 mm all-in-one liquid CPU cooler that stands out from purely utilitarian designs by incorporating both RGB lighting and an LED-backlit display on the pump head. It ships with thermal paste included and supports a broad range of current and recent Intel and AMD sockets, from LGA 1150 through LGA 1851 on the Intel side and AM4 and AM5 for AMD. The unit weighs 1394 g and comes with a one-year warranty.

Two fans running on fluid dynamic bearings handle airflow, each reaching up to 2250 RPM for a combined maximum of 85.85 CFM. The pump operates at up to 3100 RPM, and noise output spans from 19 dB at low speeds to 32.9 dB under full load. The radiator measures 282 mm in length, 120 mm in width, and 27 mm in thickness, while the water block sits at 73 × 85 mm with a 55 mm height.

Pros
  • Includes an LED-backlit display on the pump head, adding visible status information to the build
  • RGB lighting is built in for users who want a visually coordinated system aesthetic
  • Supports a broad range of CPU sockets across both current Intel and AMD platforms, including LGA 1851 and AM5
  • Dual fans with fluid dynamic bearings deliver up to 85.85 CFM of airflow while supporting quieter long-term operation
  • Thermal paste is included, allowing installation without sourcing additional materials
  • Minimum noise level of 19 dB keeps the cooler relatively unobtrusive during light workloads
Cons
  • Total weight of 1394 g is relatively heavy for a 240 mm AIO
  • Maximum noise level of 32.9 dB at full fan speed may be noticeable in quiet environments
  • Warranty period is limited to one year
  • The 240 mm radiator size may not be compatible with all case configurations, particularly smaller builds
Who is this for?

The DeepCool LS520 SE Digital suits builders who want liquid cooling alongside visible aesthetics, thanks to its RGB lighting and LED-backlit pump-head display. Its broad socket coverage — spanning LGA 1150 through LGA 1851 and both AM4 and AM5 — makes it a practical fit for a wide range of current and recent Intel and AMD platform builds. The included thermal paste and dual fluid dynamic bearing fans also make it a solid pick for users who want a straightforward installation without sourcing extra components.

Who is this NOT for?

Users working within small form factor cases that lack a 240 mm radiator mount will find this cooler incompatible with their setup. At 1394 g, the overall weight is on the higher end, which may be a concern for builds where transport or case handling is frequent. Those who prefer a clean, understated build without lighting elements will also find the RGB and display features unnecessary additions they cannot opt out of.

Cooling:

Cooling type AIO liquid
Max fan RPM 2250 rpm
Max pump RPM 3100 rpm
Max airflow 85.85 CFM
Number of fans 2

This is an AIO liquid cooling setup driven by two fans that each reach a maximum of 2250 RPM, producing a combined airflow of 85.85 CFM. The pump runs at up to 3100 RPM, circulating coolant through the loop to support consistent heat transfer away from the CPU.

Dimensions:

Heatsink/water block height 55 mm
Heatsink/water block width 73 mm
Heatsink/water block depth 85 mm
Radiator size 240 mm
Radiator height 27 mm
Radiator length 282 mm
Radiator width 120 mm

The water block measures 73 mm wide, 85 mm deep, and 55 mm tall, keeping its motherboard footprint compact. The 240 mm radiator runs 282 mm in length and 120 mm in width, with a 27 mm thickness that fits standard slim radiator mounts without requiring extra case clearance.

General info:

CPU socket LGA 1851, LGA 1700, LGA 1200, LGA 1151, LGA 1150, LGA 1155, AM4, AM5
Audible noise (min) 19 dB
Audible noise (max) 32.9 dB
weight 1394 g
warranty period 1 years

The cooler supports a wide range of Intel and AMD sockets, spanning LGA 1150 through LGA 1851 on the Intel side and both AM4 and AM5 for AMD. Audible noise ranges from 19 dB at its quietest up to 32.9 dB at full load, and the total weight comes in at 1394 g. A one-year warranty is provided.

Features:

Fan bearings Fluid dynamic bearings
has RGB lighting ✓
Thermal paste Included
Has a display ✓
Display type LED-backlit

The fans run on fluid dynamic bearings, and the unit includes both RGB lighting and an LED-backlit display on the pump head, adding a visual element to the build. Thermal paste is included in the box, so no separate purchase is needed before installation.

Final Verdict

The DeepCool LS520 SE Digital is a 240 mm AIO liquid cooler that positions itself clearly for builders who want thermal performance alongside visual customization, combining RGB lighting and an LED-backlit pump-head display with dual fluid dynamic bearing fans and wide platform support across modern Intel and AMD sockets. The one-year warranty and overall weight are worth factoring in, and the fixed aesthetic elements mean it is not the right fit for minimalist builds. For users who want a feature-complete AIO that covers both cooling function and build presentation in a single package, the LS520 SE Digital delivers a coherent and well-specified solution.
