DeepCool LS720 SE 360mm ARGB Liquid Cooler - Quiet High Performance

In this review of the DeepCool LS720 SE the bottom line is simple: this 360mm all-in-one liquid cooler is aimed at builders who want strong thermal performance with a striking ARGB infinity mirror block. The review finds the LS720 SE best for users upgrading mid to high-end CPUs who value a quieter pump and fans along with a polished aesthetic. The 4th generation pump and thick copper cold plate deliver efficient heat transfer, while the included ARGB fans and mirror-plated top give the build a premium look without complicated custom loops.

Key Features

• 4th Gen Dual-Chamber Pump: The microchannel design and three-phase brushless motor optimize coolant flow and support sustained cooling under load.
• High RPM Capability: The pump is rated up to 3100 RPM to help manage heat during heavy CPU use while still allowing quieter operation with the low-speed adapter.
• Thick Copper Plate: A pure copper cold plate maximizes thermal conductivity for consistent and efficient CPU heat transfer.
• ARGB Infinity Mirror Block: A mirror-plated top cover with 16 LEDs and a narrow frame creates a deep infinite reflection to coordinate visually with system lighting.
• 120mm ARGB PWM Fans: Fans provide strong static pressure and airflow for radiator efficiency, and a low-speed adapter can reduce maximum noise by up to 10dB.
• Anti-Leak Technology: The patented internal valve regulates and purges excess pressure to extend the unit's usable life.

Who It's For

The DeepCool LS720 SE is well suited for PC enthusiasts and gamers building or upgrading a mid-range to high-end desktop who want a 360mm radiator for better thermal headroom. It is also a good match for users who place value on appearance, since the infinity mirror and ARGB fans provide a noticeable visual upgrade to many builds.

Those who need ultra-compact solutions for small form factor cases should look elsewhere, as a 360mm radiator requires a compatible case with space for three 120mm fans. Slot-in users who prefer passive or air-only cooling for simplicity may also find a large AIO more than they need.

Pros & Cons

Pros

• Strong cooling components, including a 4th generation pump and a thick copper plate, support sustained thermal performance.
• ARGB infinity mirror and smooth aluminum housing give a premium visual finish and easy color coordination.
• Included low-speed adapter and PWM fans let builders balance noise and cooling power effectively.
• Patented Anti-Leak Technology addresses long-term reliability concerns with built-in pressure regulation.

Cons

• 360mm radiator size limits compatibility to larger cases, so it is not ideal for small form factor builds.
• High maximum pump RPM may produce measurable noise if run at top speed without the low-speed adapter.

Frequently Asked Questions

Does this cooler fit all CPU sockets?
The LS720 SE includes sturdy mounting brackets for both Intel and AMD sockets and is designed for common modern CPU platforms.

How does the Anti-Leak Technology help?
The internal valve regulates and purges pressure when it rises above atmospheric pressure, which helps protect the loop and prolong the unit's useful life.

Can it be quiet during light use?
Yes, the included low-speed adapter reduces maximum fan noise by up to 10dB and the pump supports lower speeds for quieter operation.
