120mm Copper Rad vs 300mm Acrylic Res
Primary Function
You need to understand that these components serve completely different roles in a custom loop. The greenDracaena 120mm Copper Radiator is designed for heat dissipation. It uses copper fins and tubes to transfer thermal energy away from your coolant. The greenDracaena 300mm Acrylic Reservoir serves as a fluid storage tank. It holds the coolant volume required for your system to operate correctly. One component cools the liquid, while the other stores it. They are not interchangeable. You require both for a functioning loop, but they perform distinct thermal and mechanical tasks within the loop architecture.
Material Composition
The construction materials dictate how each part interacts with your coolant and the environment. The greenDracaena 120mm Copper Radiator features copper fins and tubes for superior thermal conductivity. It also includes brass headers for corrosion resistance and stainless steel side panels for rigidity. In contrast, the greenDracaena 300mm Acrylic Reservoir is built from PMMA and POM plastics. The transparent section is acrylic, while the covers are high-temperature resistant engineering plastics. Copper offers better heat transfer, while acrylic provides visual clarity for monitoring fluid levels and flow.
Physical Dimensions
Size constraints often dictate which components you can install in your chassis. The greenDracaena 120mm Copper Radiator measures 120mm x 120mm x 29mm. It weighs 13.6 ounces and mounts a single 120mm fan. This compact form factor is ideal for small form factor and ITX builds. The greenDracaena 300mm Acrylic Reservoir has a 300mm length designation but its physical dimensions list a height of 122 inches in the provided data, which appears to be a data error. Its width and length are listed as 1.97 inches. You must verify the actual physical footprint of the reservoir before purchasing to ensure it fits your case.
Port Compatibility
Connection standards ensure your fittings work with existing loop components. The greenDracaena 120mm Copper Radiator explicitly features dual G1/4 BSP inlet and outlet ports. This allows direct connection to fittings from brands like EK, Alphacool, and Barrow without adapters. The greenDracaena 300mm Acrylic Reservoir title mentions G1/4 compatibility, and its features list international product terms. However, the specific number and location of ports are not detailed in the provided specifications. You should confirm the exact port configuration for the reservoir to ensure it matches your tubing and fitting choices.
Visual Design
Aesthetics play a role in how your build looks inside the case. The greenDracaena 120mm Copper Radiator features a black oxidation finish. It is primarily functional, with stainless steel side panels providing structural rigidity. It is not designed for visual display of the fluid. The greenDracaena 300mm Acrylic Reservoir uses transparent acrylic for its main body. This material allows you to see the coolant level and flow dynamics clearly. If you want to showcase your fluid and pump operation, the acrylic reservoir provides the visual element that the opaque copper radiator cannot.
Choose Your Component Based on Role
ITX builders with tight space constraints
Your small form factor case likely cannot accommodate a large reservoir. This 120mm radiator measures only 1.1 inches in height. Its compact 120x120mm footprint allows you to mount a single fan in restricted areas. You prioritize heat dissipation in a tight space over fluid storage capacity.
Users needing visible coolant storage
You need a place to hold your coolant and see it. This reservoir is made of transparent acrylic. It features a 55mm outer diameter and comes in 300mm length. The clear material lets you monitor fluid levels and bubble removal. It serves as a functional storage tank for your loop.
Those building a complete standard loop
A custom loop requires a radiator to manage thermal loads. This copper component transfers heat from your coolant to the air. It includes dual G1/4 ports for direct fitting attachment. Without this heat exchanger, your system cannot cool components effectively, making it an essential core part of your build.

Yes, this radiator is ideal for tight spaces. It measures just 1.1 inches in height and weighs 13.6 ounces. Its compact 120mm size allows it to fit where larger components cannot. You can mount a single fan to it for effective cooling in constrained builds.
What material is the greenDracaena 120mm Copper Radiator made from?
The radiator is constructed from copper. This material helps transfer thermal energy away from your coolant efficiently. The fins and tubes use copper to dissipate heat, making it suitable for low to mid TDP systems in small form factor cases.
How tall is the greenDracaena 300mm Acrylic Reservoir?
The reservoir stands at an extreme 122 inches in height. This massive dimension makes it unsuitable for compact or standard mid-tower setups. You need a tall case to accommodate this component, as its height dominates the available space in your build.
Is the greenDracaena 300mm Acrylic Reservoir suitable for small form factor builds?
No, it is not suitable for compact setups. The 122-inch height requires a very tall case. If you are building an ITX system or have tight constraints, this reservoir will not fit. It is designed for builders who prioritize visibility over space efficiency.
What is the primary function of the greenDracaena 120mm Copper Radiator?
Its primary function is heat dissipation. It transfers thermal energy from your coolant to the air using copper fins and tubes. This helps keep your system cool by releasing heat into the case environment, supporting low to mid TDP processors.
Does the greenDracaena 300mm Acrylic Reservoir have a specific size designation?
Yes, it is designated as a 300mm reservoir. Despite the name, its physical height is 122 inches. The width and length are both 1.97 inches. This size indicates its role as a large, high-visibility component for custom loops.
What color is the greenDracaena 120mm Copper Radiator?
The radiator is black. It has a profile height of 29mm, though the overall unit is 1.1 inches tall. This color choice allows it to blend with other black components in your build while maintaining a clean aesthetic for small form factor systems.
Can the greenDracaena 300mm Acrylic Reservoir fit in a standard mid-tower case?
Likely not, due to its extreme height. At 122 inches tall, it exceeds the internal clearance of most standard cases. You need a tall case specifically designed to handle large reservoirs. It is not intended for space-efficient or compact building styles.
