GPU CPU Backplate Copper Heatsink Round Pipe 5mm x 160mm - Passive

Our review of the GPU CPU Backplate Copper Heatsink Round Pipe looks at a single 160mm copper heat pipe aimed at DIY PC and laptop cooling tasks. The bottom line: this is for builders who need a compact, passive thermal conductor to move heat from a small IC or memory module to a larger radiator or chassis area. It stands out because the tube combines solid copper with a thermal fluid core, offering rapid thermal response and higher effective conductivity than plain metal, making it useful where a thin, fanless solution is required.

Key Features

• Material: Solid copper body with an internal thermal fluid provides strong heat conduction and responsiveness for small heat sources.
• Dimensions: A 160mm length and 5mm diameter make the tube easy to route in tight spaces inside laptops or compact desktops.
• Passive operation: Works without a fan, enabling quieter builds and supporting passive heat transfer from GPU, CPU backplates, or VRAM chips.
• Custom processing: The maker can bend or flatten the pipe to match contact surfaces, which helps adapt the tube to nonstandard layouts.
• Versatile applications: Designed to link chipsets, LED modules, or small radiators to improve overall heat dissipation capacity.
• Sharp-to-smooth ends: The narrow contact end provides precise thermal pickup while the smooth end helps spread heat to a dissipation area.

Who It's For

This copper heat pipe suits PC enthusiasts, repair technicians, and DIY laptop modders who need a small, passive thermal solution to move heat from a localized hotspot to a chassis or secondary heatsink. It is particularly useful when space prevents larger heatsink assemblies and when silent operation is important.

It is not aimed at users who need a complete cooling kit with mounting hardware or those who require active cooling performance for high-TDP processors; in such cases a full fan-cooled heatsink or liquid loop is a better choice.

Pros & Cons

Pros

• High thermal responsiveness from the combination of copper and thermal fluid improves heat transfer over plain metal in tight applications.
• Compact 5mm diameter and 160mm length make it easy to route through tight chassis or under backplates.
• Manufacturer offers bending and flattening services, so the pipe can be adapted to specific contact profiles.
• Passive, fanless operation reduces noise and can be used in silent or low-airflow systems.

Cons

• Sold as a single pipe without mounting brackets or thermal pads, so additional hardware or modification is required for many installations.
• Not a complete cooling solution for high-power CPUs or GPUs that need active cooling to maintain safe temperatures.

Our Verdict

The Bopaodao 5mm x 160mm copper heat pipe is a good-value component for builders needing a compact, passive thermal conductor to move heat from chips to a radiator or chassis. It is most useful when customized shaping is required and where silent, low-profile cooling is preferred over high-capacity active systems.

Frequently Asked Questions

Can this pipe be bent to fit a custom layout?
Yes, the seller offers bending and flattening processing services so the tube can be matched to specific installation shapes.

Is this product a complete cooling kit?
No, it is a single passive heat pipe sold without mounting hardware or thermal pads; additional components are needed for a finished installation.

Will it cool a high-power CPU or GPU on its own?
Not likely; this pipe helps move heat but is intended for supplementing radiators or improving dissipation for smaller hotspots rather than replacing active cooling for high-TDP parts.
