Fan Airflow and Static Pressure Dynamics
Liquid cooling efficiency relies heavily on the ability of radiator fans to force air through tightly spaced aluminum cooling fins. The DeepCool LT720 delivers documented airflow metrics designed specifically to conquer high-density fin resistance. Its three 120mm hydrodynamic bearing fans generate an impressive DeepCool LT720 airflow CFM rating of 85.85 CFM alongside 3.27 mmAq of static pressure at 2250 RPM. This substantial pressure ensures that fresh air penetrates completely through the radiator channels rather than deflecting backward, providing rapid heat dissipation under sustained rendering or compute tasks. Similar high-resistance dynamics are explored in our breakdown of the arctic liquid freezer iii 360 vs deepcool lt720.
In contrast, the manufacturer listing for the Galahad II 360 Trinity SL-Inf does not publish explicit CFM or static pressure measurements. While Lian Li equips this model with its renowned SL-Infinity fan design, the absence of verified flow specifications leaves performance metrics to real-world observation rather than manufacturer-guaranteed tolerances. The Galahad II relies on its high-end Trinity radiator pairing to keep desktop processors within safe operating temperatures, but buyers focusing strictly on Lian Li Galahad II 360 cooling performance must weigh aesthetic prestige against the lack of official airflow data sheets.
When dealing with high-wattage desktop processors, documented static pressure creates predictable thermal margins. The 3.27 mmAq rating of the LT720 represents exceptional force for an all-in-one liquid cooler fan, allowing it to exhaust trapped heat far more aggressively than general-purpose case fans running at identical rotations.
Edge: DeepCool LT720 because its documented 85.85 CFM airflow and 3.27 mmAq static pressure provide guaranteed air penetration across dense radiator fins.
Pump Velocity and Liquid Circulation Mechanics
Coolant velocity within an all-in-one loop dictates how quickly heat transfers from the CPU integrated heat spreader to the radiator core. The DeepCool LT720 features an internal motor operating at 3100 RPM while drawing 4.56W of power at 0.38A across a 3-pin motherboard header. This elevated rotational speed accelerates liquid flow through the copper base plate micro-channels, preventing thermal saturation when a multi-core processor spikes under sudden computational workloads. Liquid displacement is further complemented by a compact 94 x 80 x 68 mm pump housing that minimizes footprint around motherboard VRM heatsinks.
For the Galahad II 360 Trinity SL-Inf, the official product listing omits the exact pump impeller speed, electrical draw, and dimensional parameters. The cooler incorporates Lian Li Trinity pump cap architecture, engineered to offer interchangeable visual styles directly over the CPU block. While this provides unrivaled visual customization at the center of the motherboard, builders cannot verify the mechanical circulation rate from the listing specifications alone. Those interested in seeing how alternative liquid coolers handle high-draw pump circulation can compare the corsair icue h150i elite vs lian li galahad ii 360.
The operational benefit of the LT720 pump design lies in combining high liquid velocity with an acoustic rating of only 19 dB(A). Maintaining 3100 RPM while keeping motor hum below ambient room sound ensures steady liquid transfer without introducing high-pitched mechanical whine into your chassis.
Edge: DeepCool LT720 due to its verified 3100 RPM liquid circulation speed and exceptionally quiet 19 dB(A) pump motor rating.
Acoustic Profile and Noise Suppression
System acoustics determine daily computing comfort, particularly when a cooling loop ramps up under heavy gaming or video export duties. Examining the DeepCool LT720 noise level reveals a dual-mode acoustic profile. At unrestricted operation, the 120mm hydrodynamic bearing fans spin up to 2250 RPM, generating a peak noise level of 32.9 dB(A). However, DeepCool integrates a low-speed noise reduction line directly into the package. Connecting this hardware adapter caps fan speeds between 500 and 1600 RPM, reducing maximum airflow to 60.85 CFM and dropping acoustic output to a remarkably quiet 28.2 dB(A).
The product data for the Lian Li Galahad II 360 noise level does not specify baseline or maximum decibel outputs. The Trinity SL-Inf configuration utilizes fluid dynamic bearings within its specialized fan casing, which typically suppress motor resonance, but tuning acoustic boundaries requires manual PWM adjustment inside your motherboard BIOS or software suite rather than relying on manufacturer-supplied inline adapters.

Having dedicated speed reduction hardware gives the LT720 a distinct advantage for silence-oriented builders. Users who prefer not to tinker with custom fan software can simply plug in the reduction line to ensure their desktop never crosses the 29 dB threshold under heavy thermal loads.
Edge: DeepCool LT720 because the included hardware reduction lines lower operational fan noise down to 28.2 dB(A) alongside an ultra-quiet 19 dB(A) pump.
Aesthetic Design and Cable Management
Chassis presentation is where the balance between these two liquid coolers shifts decisively. In any thorough Lian Li Galahad II 360 review, the central highlight is Lian Li Trinity SL-Infinity ecosystem. The Galahad II 360 integrates interlocking fan frames that slide and lock together, passing power, PWM control, and addressable RGB illumination through pin-to-pin contacts. This modular architecture eliminates the mess of separate fan cables, leaving only a single unified connection running behind the motherboard tray. Paired with infinity mirror accents along the fan edges and a multi-layered ARGB pump cap, the cooler serves as a dramatic centerpiece for panoramic tempered glass cases.
The DeepCool LT720 takes a different design approach, centered on a geometric multidimensional infinity mirror block that draws 3.15W via a standard 3-pin 5V addressable RGB header. While the pump block provides a modern, crystalline lighting effect, its three cooling fans use standard individual frame structures. Managing the wiring requires routing traditional 4-pin PWM and lighting splitters through chassis grommets, requiring more effort during system assembly to achieve a tidy appearance.
