GPU CPU Backplate Copper Heatsink Round Pipe 5mm x 140mm - Fanless

In this review of the GPU CPU Backplate Copper Heatsink Round Pipe from Bopaodao, the bottom line is straightforward: this single 140mm copper heat pipe is best for DIY system builders or laptop repair techs who need a compact, passive cooling upgrade. The reviewer found it most valuable where space is limited and noisy fans are undesirable, because the copper tube combines metal conduction with a thermal fluid core that improves responsiveness and carries heat away from small ICs and VRAM more effectively than a bare metal rod.

Key Features

• Material and construction: Solid copper shell with a thermal fluid core offers better heat exchange than plain metal and speeds thermal response when mounted on hotspots.
• Compact size: At 140mm length and 5mm diameter the tube fits tight spaces inside laptops, GPUs, and small PC builds where larger heatsinks cannot be used.
• Passive cooling: The design allows fanless operation or augmentation of existing radiators, reducing noise while improving heat spread to a connected radiator or backplate.
• Customizable shape: The seller offers bending and flattening services so the pipe can be formed to match uncommon mounting paths and improve contact with chips.
• Versatile application: Useful for GPU backplates, CPU deltas, VRAM, chipset modules and LED assemblies that need targeted thermal management.

Who It's For

This component is aimed at experienced hobbyists, small-system integrators, and repair technicians who want a compact, passive heat transport solution for tight electronics assemblies. It is especially useful when replacing or supplementing cramped laptop cooling runs or when creating a custom heat spreader for a graphics card backplate.

It is not a turnkey cooler for users who want an out-of-box mounting bracket or a complete fan/heatsink assembly; novices who need plug-and-play GPU coolers or thermal pads only should look for full kits with mounting hardware instead.

Pros & Cons

Pros

• Excellent thermal responsiveness from a thermal fluid core that enhances heat transfer compared with a plain copper rod.
• Thin, long form factor fits into narrow channels and along backplates without obstructing other components.
• Available bending and flattening services let buyers adapt the pipe to specific mounting geometries.

Cons

• Sold as a single tube without mounting clips or pads, so some DIY skill and additional materials are required for installation.
• Not a full cooling solution by itself; it needs to be connected to a radiator or conductive backplate for effective dissipation.

Our Verdict

The Bopaodao copper heat pipe is a compact, cost-effective component for builders who need passive heat transport in tight assemblies. It offers improved thermal responsiveness over plain copper rods and useful customization options, making it a good value for technicians and modders who can provide their own mounting hardware and pair it with a radiator or backplate.

Frequently Asked Questions

Can this tube be bent to fit my layout?
Yes, the seller provides bending and flattening services; contact them with your requirements before ordering.

Will it cool a GPU by itself?
No, the pipe moves heat but needs to be connected to a radiator, backplate, or other dissipation surface to be effective.

Is the material suitable for laptop ICs?
Yes, the copper shell and thermal fluid core are intended for hotspots like laptop IC chipsets, VRAM, and LED modules where compact passive cooling is required.
