Description

Description

The DeepCool LS720 SE is an all-in-one CPU cooler that provides reliable and high-performance cooling, based on a new water pump design for optimal results. 

You can synchronize it with the rest of your system, as it features a large and bright ARGB (Addressable RGB) cover on the top surface of the CPU block and fans with ARGB support.

A new era of DeepCool based on the design of the 4th generation high-performance water pump that maximizes cooling efficiency with

  • Optimized microchannels that ensure efficient coolant flow.
  • Powerful three-phase motor operation up to 3100 RPM.
  • Thick solid copper frame provides a flawless fit without gaps.

Radiant Reflections

A mirrored cap with a narrow frame offers a unique reflection from the 16 RGB LEDs. The sleek aluminum casing adds a premium feel and a radiant shine.

Efficiency at its Finest

Maintain your computer's cooling with the 120mm ARGB PWM fans, which combat heat with maximum static pressure and strong airflow. The included low-speed adapter reduces maximum noise by up to 10dB for absolute quiet.

  • 500~2250 RPM Dynamic PWM Range
  • 85.85 CFM Supreme Airflow
  • 3.27 mmAq Air Pressure
  • ≤32.9 dB(A) Full Load Noise

Adjust the lighting as you wish

Easily control and synchronize the RGB lighting effects of your cooler through compatible motherboards and controllers for full customization.

Quick and easy installation

Durable mounting brackets are included for both Intel and AMD sockets, which are simple and easy to install.

Tube Length
410 mm

Tube Length

The Tubing Length (mm) indicates how long the tubes connecting the pump to the radiator of the liquid cooling system are, and it directly affects the ease of installation inside the case. A longer length offers more flexibility in radiator placement (e.g., in large cases or in different positions such as the top or front), while a shorter length results in a more “compact” setup but with limited placement options.
Radiator Material

Technical Specifications

Fan Speed (max)
2250 rpm

Fan Speed (max)

The fan speed determines how fast it spins, affecting airflow and noise level.

  • Low (500-1000 RPM): Quiet operation, ideal for low-noise builds, but with less airflow.
  • Medium (1000-1800 RPM): Balanced performance between cooling and noise.
  • High (1800+ RPM): Maximum airflow, suitable for demanding conditions or overclocking, with increased noise.
Fan Noise Level (Full Load)
32.9 dB

Fan Noise Level (Full Load)

The Fan Noise Level (Full Load) indicates how much noise the liquid cooler’s fans produce when operating at maximum speed, that is, under full load. It is measured in dB(A), and the lower the value, the quieter the operation. This is an important feature for those who want a quiet system, especially in demanding uses such as gaming or rendering where the fans run at maximum.
Air Flow
60.85 cfm

Air Flow

Airflow (CFM) indicates the volume of air that the fan moves per minute (Cubic Feet per Minute) and directly affects the cooling performance of the radiator. The higher the value, the more air passes through the radiator, contributing to better heat dissipation, although it is usually accompanied by increased noise.
Air Pressure
3.27 mmH₂O: millimeters of water

Air Pressure

Air Pressure (mmAq) indicates the force with which the fan pushes air through obstacles such as the radiator and is measured in mm of water column. The higher the value, the better the fan can penetrate the dense fins of the radiator, making it more efficient for water cooling compared to regular case fans.
Bearing Type
Hydraulic

Bearing Type

Hydraulic
Hydraulic bearings use a special pressurized lubricant system for smooth rotation, offering low noise, good durability, and balanced performance for everyday use.

    Amazing CPU cooler, it keeps my processor (Ryzen 7 9800x3d) always below 65 degrees Celsius regardless of the load.

    This review is about colour: Black, lighting: RGB

    Very good AIO but be careful because the radiator is big and it didn't fit on top so I had to put it in the front and still lost 1 case fan below because it doesn't fit. The case is the Barrett No8.

    Ryzen 5 3600 reached up to 67C in Cinebench with a boost of 4.1ghz.
    Idle ~40C depends on the fan curve and how much noise you want
