Component Differences and Specs
Material construction
The greenDracaena 120mm Copper Radiator uses copper fins and tubes for superior thermal conductivity. Brass headers provide corrosion resistance, while stainless steel side panels add structural rigidity. This combination is engineered for optimal heat transfer and long-term durability. In contrast, the greenDracaena D-pump 650L/H PC Water does not specify its internal material composition in the provided data. You get detailed metallurgy for the radiator, but the pump’s internal build materials remain undefined. If material transparency matters for your loop’s longevity, the radiator offers clear advantages here.
Size and fit
The greenDracaena 120mm Copper Radiator measures 120mm by 120mm by 29mm. It weighs 13.6 ounces and mounts a single 120mm fan. This compact footprint is ideal for small form factor and ITX builds where space is tight. The greenDracaena D-pump 650L/H PC Water is taller, standing 4.5 inches high with a 50mm outer diameter. It includes a 65ml reservoir. While the radiator is a flat panel for airflow, the pump is a vertical unit. You need different mounting strategies for each component based on their distinct physical dimensions.
Flow performance
The greenDracaena D-pump 650L/H PC Water delivers a 650L/H flow rate at a 3.5m pump head. It runs at 12W on DC 12V, providing reliable coolant circulation for full custom loops. This performance supports CPU blocks, GPU blocks, and multiple radiators. The greenDracaena 120mm Copper Radiator does not list flow specifications. It is a passive cooling component that relies on the pump for movement. You cannot compare flow rates directly, as the radiator facilitates cooling while the pump drives the liquid. The pump provides the active performance metric here.
Lighting features
The greenDracaena D-pump 650L/H PC Water includes a 10-color RGB status indicator. This LED cycles through colors to confirm pump operation at a glance. It adds visual appeal to open-frame or windowed builds. The greenDracaena 120mm Copper Radiator has no lighting features listed. It features a black oxidation finish but does not emit light. If you want visible status feedback and aesthetic lighting in your loop, the pump is the clear choice. The radiator remains a purely functional component without illumination options.
Protection features
The greenDracaena D-pump 650L/H PC Water integrates multi-level protection. It covers over-voltage, dry-run, and locked-rotor conditions for safe long-term operation. This safeguards the system during sustained gaming or overclocking loads. The greenDracaena 120mm Copper Radiator does not list electronic protection features. It is a passive metal component. You rely on the pump’s sensors and circuitry for loop safety. If operational protection is a priority, the pump provides essential safeguards that the radiator cannot offer.

The radiator measures 6.05 inches in length, 4.76 inches in width, and 1.1 inches in height. It has a profile thickness of 29mm. This compact footprint allows it to fit into tight spaces within small form factor cases where larger cooling units would not fit.
How much does the greenDracaena 120mm Copper Radiator weigh?
The unit weighs 13.6 ounces. This light weight is due to its copper construction and stainless steel side panels. The manageable mass makes it easy to mount in compact ITX builds without adding excessive strain to the case structure.
What is the flow rate of the greenDracaena D-pump?
The pump provides a flow rate of 650 liters per hour. This specification indicates the volume of coolant it can move through your loop. It is designed to provide reliable circulation for small custom loops, particularly in space-constrained SFF systems.
What are the physical dimensions of the greenDracaena D-pump?
The pump measures 2.6 inches in width, 4.5 inches in height, and 2.6 inches in length. Its small cubic shape allows it to be mounted in very confined areas. This size makes it suitable for builders who need to maximize internal case space.
Is the greenDracaena 120mm Copper Radiator suitable for high-end overclocking?
No, it is not designed for high-end overclocking. The verdict states it is best for low-to-mid TDP processors in compact builds. If you plan to push a CPU to its thermal limits, this radiator may not provide sufficient cooling capacity for your needs.
Does the greenDracaena D-pump offer speed control features?
You should avoid this pump if you need speed control. The product description explicitly advises against it for users requiring adjustable flow rates. It is intended for builders who prioritize a small form factor and reliable, fixed-flow performance over adjustable settings.
What material is used for the fins in the greenDracaena 120mm Copper Radiator?
The radiator uses copper for its fins and tubes. Copper is chosen for its superior thermal conductivity compared to aluminum. This material choice helps transfer heat away from your CPU block more efficiently, which is critical for maintaining stable temperatures in small cases.
What thread standard do these components use?
Both components share the G1/4 BSP thread standard. This is the industry standard for custom water cooling fittings and connectors. You can easily attach standard tubing, fittings, and blocks to both the radiator headers and the pump without needing special adapters.
