DeepCool LS720 SE Digital specifications and in-depth review

DeepCool LS720 SE Digital

Manufacturer: DeepCool

The DeepCool LS720 SE Digital is a 360 mm all-in-one liquid cooler designed for desktop builds that require substantial thermal headroom. It ships with three fans and includes thermal paste, making it a straightforward installation for supported platforms. The unit features fluid dynamic bearing fans, which generally contribute to smoother operation across varying speeds, and incorporates RGB lighting for those who want visual customization in their setup.

On the technical side, the fans reach a maximum of 2250 rpm with a peak airflow rating of 85.85 CFM, while audible noise spans from 19 dB at the low end to 32.9 dB at full load. The pump tops out at 3100 rpm. The radiator measures 402 mm in length and 27 mm in thickness, with the water block coming in at 55 mm tall, 73 mm wide, and 85 mm deep. Total assembly weight is 1694 g. CPU socket compatibility covers Intel LGA 1851, 1700, 1200, 1151, 1150, and 1155, as well as AMD AM4 and AM5. The product carries a one-year warranty.

Pros
  • Supports a wide range of both Intel and AMD sockets, including LGA 1851, LGA 1700, AM4, and AM5, covering most current desktop platforms
  • Three fans deliver a combined maximum airflow of 85.85 CFM, providing strong airflow across the 360 mm radiator surface
  • Fluid dynamic bearings on the fans contribute to smoother rotation and reduced mechanical noise over time
  • RGB lighting is built in, allowing integration with illuminated builds without needing additional hardware
  • Thermal paste is included in the box, so installation can proceed without sourcing a separate compound
  • Minimum noise level of 19 dB indicates the system can operate quietly under light thermal loads
Cons
  • The warranty period is only one year, which is relatively short for an AIO liquid cooler
  • At 1694 g, the total assembly weight is considerable and may add stress to the motherboard during transport or in certain orientations
  • The cooler does not include an integrated display on the pump head, which some users in this category expect for monitoring or customization
  • The 360 mm radiator requires a case with adequate mounting space, limiting compatibility with smaller or mid-tower enclosures that lack sufficient room
Who is this for?

This cooler suits users running high-thermal-load desktop builds who need a 360 mm radiator to manage heat across extended workloads. The broad socket support spanning Intel LGA 1851 through LGA 1155 and AMD AM4 and AM5 makes it a practical fit for anyone building or upgrading on current or recent platforms without worrying about mounting compatibility. Those who prioritize a quiet baseline operation at 19 dB will also find it appropriate for noise-sensitive environments, and users who want RGB integration in an illuminated setup will appreciate that the lighting is built in without requiring additional accessories.

Who is this NOT for?

This unit is not well suited for compact or mid-tower cases that lack the clearance to mount a 360 mm radiator, as the 402 mm radiator length demands adequate internal space that smaller enclosures typically cannot provide. Users who expect an integrated pump-head display for real-time monitoring or aesthetic customization will find this model lacking, as no such display is included. Additionally, the 1694 g total weight makes it a poor match for anyone who frequently transports their system, since the assembly mass can place considerable strain on the motherboard and mounting hardware during movement.

Cooling:

Cooling type AIO liquid
Max fan RPM 2250 rpm
Max pump RPM 3100 rpm
Max airflow 85.85 CFM
Number of fans 3

The LS720 SE Digital uses an AIO liquid cooling setup and draws on three fans to move air through the system, each capable of spinning up to 2250 rpm for a combined maximum airflow of 85.85 CFM. The pump runs independently of the fans and reaches a peak speed of 3100 rpm, allowing thermal output to be managed across two separate axes of control.

Dimensions:

Heatsink/water block height 55 mm
Heatsink/water block width 73 mm
Heatsink/water block depth 85 mm
Radiator size 360 mm
Radiator height 27 mm
Radiator length 402 mm
Radiator width 120 mm

The water block measures 55 mm tall, 73 mm wide, and 85 mm deep, keeping its footprint compact over the CPU socket. The 360 mm radiator extends to 402 mm in length and 120 mm in width, with a thickness of 27 mm, which is a relevant consideration when assessing clearance inside a chassis.

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 1694 g
warranty period 1 years

The cooler is compatible with a broad range of sockets, covering Intel LGA 1851, 1700, 1200, 1151, 1150, and 1155 alongside AMD AM4 and AM5, making it usable across a wide range of current and recent platforms. Audible noise ranges from 19 dB at its quietest to 32.9 dB under full load, and the complete assembly weighs 1694 g. The product is backed by a one-year warranty.

Features:

Fan bearings Fluid dynamic bearings
has RGB lighting ✓
Thermal paste Included
Has a display ✕

The fans use fluid dynamic bearings, and the unit includes RGB lighting for visual customization within a build. Thermal paste comes included in the package, removing the need for a separate purchase before installation. The cooler does not feature an integrated display on the pump head or elsewhere on the unit.

Final Verdict

The DeepCool LS720 SE Digital positions itself as a capable 360 mm AIO liquid cooler with genuinely broad platform compatibility, covering the full range of current Intel and AMD sockets, and a noise floor that keeps operation unobtrusive under lighter loads. Its three-fan, 360 mm radiator configuration gives it the thermal surface area needed for demanding desktop workloads, while fluid dynamic bearings and included thermal paste reflect a thoughtful approach to out-of-box usability. The absence of a pump-head display and the one-year warranty are worth noting for buyers who prioritize those aspects, and the radiator dimensions mean case compatibility requires careful verification beforehand. Overall, the LS720 SE Digital is a well-specified AIO for users who need wide socket support, solid airflow, and RGB integration in a large-radiator format.
