DEEPCOOL LT720 360mm AIO Liquid Cooler - High Performance Cooling

In this review of the DEEPCOOL LT720 360mm AIO liquid cooler, the bottom line is simple: builders who need strong sustained CPU cooling and eye-catching RGB should consider this unit. The reviewer found the 4th generation dual-chamber pump and thickened copper base deliver markedly improved heat transfer and mounting stability, while the included FK120 fans push high airflow for meaningful temperature drops under load. For anyone assembling a high-TDP gaming or workstation build the LT720 offers tangible performance and visual flair in a single package.

Key Features

• 4th Gen Dual-Chamber Pump: The redesigned pump and water channel increase heat transfer efficiency and help maintain consistent cooling under extended loads.
• High Pump Speed: The strong three-phase inner loop motor spins up to 3100 RPM, improving coolant circulation for faster heat removal from the CPU.
• Thickened Copper Base: A larger copper contact area provides a more stable, secure interface with the CPU for better thermal conductivity.
• FK120 Fans: Three included 120 mm fans deliver high airflow and pressure while keeping noise controlled, allowing aggressive cooling without excessive sound.
• Anti-Leak Tech: A pressure relief device integrated into the radiator helps prevent leakage risk after long-term thermal cycling.
• ARGB Lighting: Addressable RGB on the pump block supports motherboard sync for coordinated lighting effects in RGB software.

Who It's For

The LT720 is best for PC builders who plan to run high-TDP CPUs in sustained workloads or want a strong all-in-one cooler for gaming rigs and content creation systems. Its 280 W TDP cooling capability and powerful pump make it suitable for overclockers and users replacing stock cooler solutions.

It is less appropriate for ultra-compact cases that cannot accommodate a 360 mm radiator or for users seeking a completely silent passive solution; those users should look at smaller AIOs or low-noise air coolers instead.

Pros & Cons

Pros

• Very efficient heat dissipation thanks to the high-density radiator and 4th generation pump design.
• Strong pump and FK120 fans deliver high airflow and solid pressure for consistent cooling performance.
• Sturdy thickened copper base gives reliable contact and better heat transfer at the CPU surface.
• ARGB pump block offers attractive customizable lighting that syncs with mainstream motherboards.

Cons

• 360 mm radiator size requires a roomy case and will not fit many compact enclosures.
• High pump speeds and fan RPM under full load can produce noticeable noise compared with low-speed air coolers.

Our Verdict

The LT720 is a convincing choice for builders who need robust cooling and integrated ARGB in one package; its 4th generation pump, thick copper base, and aggressive FK120 fans deliver high thermal capacity for demanding CPUs. If you have the case space and want a performance-focused AIO with synchronized lighting, this cooler represents good value compared with separate custom-loop components.

Frequently Asked Questions

Will the LT720 fit my case?
Check for support of a 360 mm radiator at the top, front, or roof of your case; the radiator measures 402 x 120 x 27 mm so a roomy mid-tower or larger is typically required.

Does it support motherboard RGB sync?
Yes, the addressable RGB pump block uses a 3-pin +5V-D-G connector and supports mainstream motherboard RGB synchronization.

Is leakage a common concern?
The LT720 includes an anti-leak pressure relief device in the radiator designed to reduce leakage risk after prolonged thermal cycling, though normal installation care is still advised.
