Which one should you choose?
Choose Bopaodao 120mm Flat Copper Heat Pipe if
- You need a longer heat spreader at 120mm to cover a wider area.
- You require a flat surface for direct contact with a backplate or chip.
- You prefer a component made entirely of pure copper without internal fluids.
Choose Bopaodao 5mm x 90mm Copper Heat Pipe if
- You have space constraints requiring a shorter 90mm component.
- You need a round tube shape to fit into specific cylindrical mounts or gaps.
- You want a design that utilizes thermal fluid for heat exchange.
Verdict: Choose the flat copper heat pipe if you need a larger surface area and a flat profile for broad contact. Select the round copper pipe if your installation requires a smaller diameter and a shorter length. Your choice depends entirely on the physical space available around your heat source.
Flat vs Round Copper Pipes
Physical Dimensions
The Bopaodao 120mm Flat Copper Heat Pipe measures 120mm in length, 5.5mm in width, and 2mm in thickness. This flat profile offers a broad surface area for contact. The Bopaodao 5mm x 90mm Copper Heat Pipe is a round tube with a 5mm diameter and a 90mm length. The flat pipe is significantly longer and wider, making it suitable for larger backplates or wider heat spreaders. The round pipe is shorter and narrower, fitting into tighter spaces or specific cylindrical heat sources. You must choose the shape that matches your hardware geometry.
Material Composition
Both products rely on copper for thermal conductivity. The Bopaodao 120mm Flat Copper Heat Pipe is made from 99% pure copper. This high purity ensures consistent heat transfer across the flat surface. The Bopaodao 5mm x 90mm Copper Heat Pipe is described as containing copper and thermal fluid. The listing claims the thermal fluid has a conductivity 200 times that of copper. This suggests a heat pipe mechanism rather than a solid rod. If you need simple conductive mass, the pure copper flat pipe is straightforward. If you need rapid heat transport via fluid, the round pipe offers that feature.
Compatible Devices
Both products list compatibility with laptops, CPUs, and GPUs. The Bopaodao 120mm Flat Copper Heat Pipe also mentions mobile phones and DIY cooling systems. Its flat shape is ideal for covering larger chips or backplates on these devices. The Bopaodao 5mm x 90mm Copper Heat Pipe explicitly lists VRAM and RAM in its compatible devices. This makes it a better choice if you need to cool memory modules on a motherboard or graphics card. The round shape allows for targeted contact with smaller, specific components like memory chips. Check your specific cooling target before deciding.
Heat Dissipation Method
Both items use a passive cooling method, meaning they do not have fans. They rely on natural convection and conduction. The Bopaodao 120mm Flat Copper Heat Pipe disperses heat across its 120mm length and 5.5mm width. This large surface area helps dissipate heat into the surrounding air. The Bopaodao 5mm x 90mm Copper Heat Pipe uses thermal fluid to move heat from the sharp end to the smooth dissipation end. This is efficient for moving heat away from a source quickly. The flat pipe spreads heat out; the round pipe moves it along its length. Both are passive, but their mechanisms differ.
Customization Options
Both manufacturers offer bending and flattening services upon request via Amazon message. The Bopaodao 120mm Flat Copper Heat Pipe has variations in length up to 150mm and various thicknesses. This allows you to select a size closer to your needs before purchase. The Bopaodao 5mm x 90mm Copper Heat Pipe has variations in diameter up to 10mm and lengths up to 280mm. This gives you more options for diameter and length combinations. If you need a specific non-standard size, both can be customized. The round pipe offers more variation in diameter, while the flat pipe offers more in thickness.
Choose your Bopaodao copper pipe
You need longer reach for heat spread
The 120mm length provides more distance for heat to travel from the source. The flat 2mm by 5.5mm profile increases surface area. This design helps dissipate heat more effectively across a wider area. You get a pure copper construction that is ideal for passive cooling applications on laptops and GPUs.
You prefer standard round pipe dimensions
This model features a classic 5mm diameter round tube. The 90mm length suits compact builds where space is limited. It uses copper with thermal fluid for rapid heat exchange. The round shape allows for easy bending and routing. This makes it a practical choice for connecting components in tight spaces.
You want maximum surface contact area
The flat geometry offers a broad contact surface compared to round pipes. This 120mm pipe measures 5.5mm wide and 2mm thick. The increased surface area improves passive heat dissipation. Pure copper ensures efficient thermal transfer. This is the better option when you need to spread heat over a larger backplate or surface.

Frequently asked questions
Is the Bopaodao 120mm flat copper heat pipe better than the 5mm round one?
It depends on your specific cooling needs. The 120mm flat pipe offers a wider surface area due to its 5.5mm width and 2mm thickness. This design is ideal for spreading heat across larger components like GPUs or laptops. The 5mm x 90mm round pipe is better for targeted cooling in tight spaces where a flat profile will not fit.
What components are compatible with these Bopaodao copper heat pipes?
Both models are compatible with GPUs, laptops, and RAM. They function as passive cooling elements for these devices. You can use them to manually extend heat dissipation paths. This makes them suitable for DIY builds where standard cooling solutions are insufficient or do not fit the available space.
Does the Bopaodao 120mm flat copper heat pipe use active cooling?
No, it uses a passive cooling method. It relies on the thermal conductivity of copper to move heat away from the source. There are no fans or moving parts involved. This makes it silent and reliable for components that generate significant heat but lack integrated active cooling solutions.
How long is the Bopaodao 5mm x 90mm copper heat pipe?
The length is 90mm, which is approximately 3.54 inches. It has a diameter of 5mm, or 0.2 inches. This compact size allows for placement in confined areas within laptops or mini-PCs. It is designed to bridge small gaps between heat sources and dissipation points.
What material are these Bopaodao cooling pipes made from?
Both products are made from pure copper. Copper is chosen for its high thermal conductivity, which efficiently transfers heat away from hot spots. This material ensures that heat is moved quickly from the component to the surrounding air or heatsink without significant resistance.
Which Bopaodao model is best for a laptop GPU?
The Bopaodao 120mm Flat Copper Heat Pipe is often preferred for laptops. Its 120mm length provides more distance for heat to travel. The flat profile increases surface area for better dissipation. However, if space is extremely limited, the 5mm x 90mm model may fit where the larger pipe cannot.
