The Deepcool LS720 WH is a 360mm CLC cooling solution. It has a 360mm radiator with three FC120 WHITE A-RGB fans.


The radiator size is 402 x 120 x 27mm with a thickness of 27mm. Adding 25mm fans increases the overall thickness to 53mm. It has a 22 FPI count and a 105mm gap between fan mounting holes. Deepcool designed it using lightweight aluminium.

The radiator has a unique design with rectangular end blocks and a dense fin stack. It features 12 channels for water flow and a DeepCool logo on the tube side. No protective sheets are over the fins, so use the supplied long screws to avoid damage during fan installation.

The radiator’s right side has a pressure-release valve, and an elastic-based pressure-released bag is on the outlet side. This bag helps maintain internal pressure, reducing the risk of leakage in the AIO.

The far head of the radiator has a non-Asetek design sticker. The cooler has E-shaped fins for a good finish. It uses two barbed fittings with metallic covers, white colour tube holders, and a full-length white tube made from anti-explosion rubber material with mesh sleeves for a clean look. The tube is approximately 410mm long.


This cooler features a compact water block with pump housing, changing the overall design from the Castle series. The block is 85x74x57mm, smaller than the Castle V2 series (91x79x47mm). It has a reflective glass top with a removable cover showcasing the DeepCool logo.

The picture displays a block with the lid off, revealing the PCB. Users can rotate the logo or use a cover plate for custom logos. Tubes on the block’s base can be rotated to the left or right. Two cables emerge from the pump housing.

The pump has a 3-pin power cable and a proprietary 6-pin A-RGB connector. The 6-pin cable is the same as on FC White edition fans, using a daisy-chain concept. The pump housing is black with no branding on the left, right, and front sides. The pump’s rated speed is 3100±RPM at 12VDC, consuming 5.64 Watts with a noise level of 19 dB(A). The base is 53x53mm with pre-applied thermal paste and 4 bracket mounting holes.


The LS720 WH includes 3 FC120 WH A-RGB fans with a square frame for a bold look. Each fan has 9 translucent blades and A-RGB LEDs in the centre. Sturdy frame with anti-vibration pads; arrows indicate blade spin and airflow direction. The 5-pin header allows fans to be daisy-chained, simplifying cable connections.

Looking at the back of the fan, we can see a 4-arms assembly holding the blades and the centre. The fans are made in China. One of the arms has a widened body carrying the power cable. We have a white colour flat cable with a proprietary 6-pin connector.

DeepCool has provided two cables in the accessory box. One cable extends the length of the cable coming from the daisy-chained fans, whereas the other connects the solution with the 4-pin PWM header and a standard 3-pin 5V header on the motherboard. It is SATA powered.

PRO TIP: When installing the DeepCool LS720 WH AIO cooler, consider mounting it at 6 o’clock orientation with the tube side facing the PCIe slot for optimal heat transfer.

A-RGB Lighting

There is no dedicated A-RGB controller provided with the cooler. There is no hub provided with the cooler either. The terminal connectors are 4-pin PWM and 3-pin, 5V, A-RGB ones.

The A-RGB lighting is compatible with:


If the fans and the block are not connected to the light source, the cooler features Auto RGB, in which the rainbow mode is activated by default and cycles through the pre-defined modes. Here are some pictures for your eye’s pleasure.


The installation is simple and convenient.

  • You need 11 components for the mounting hardware.
  • DeepCool suggests better performance when mounting at 6 o’clock with the tube side facing the PCIe slot, especially on Intel 12th gen.
  • This aligns the jet plate with the cores for maximum heat transfer.
  • We verified this claim by testing at 3 o’clock with the tube facing the DIMM slot.


The cooler is an AIO with no clearance issue for the RAM and PCIe slot. However, make sure that your case supports 360mm AIO. The dimension of the radiator without fans is 402x120x27mm (LxWxH).

Stress tests may give different results because of factors like pressure, thermal paste, and temperature. Also, silicon variations in similar chips play a role. So, it’s important to state the testing method and details.


At 3’o clock orientation, the LS720 WH matches the Fractal Design Lumen S36 RGB cooler in our tests. When we installed the LS720 WH at 6’o clock orientation, there was a 2°C improvement over the 3’o clock orientation and the Fractal cooler. Moreover, in the 6’o clock orientation, the LS720 WH showed more than a 4°C improvement in thermal performance compared to the DeepCool Castle 360EX WH A-RGB cooler. This positions the LS720 WH as our new top performer.

We are not measuring the noise level now due to environmental noise beyond our control. The fans are loud at full speed, and I would suggest PWM Auto control or a custom fan curve.
