GPU CPU Backplate Copper Heatsink Round Pipe 4mm x 70mm - Passive

In this review of the GPU CPU Backplate Copper Heatsink Round Pipe, the bottom line is simple: it is a compact, passive cooling accessory best suited for hobbyists and system builders who need a targeted thermal bridge for small hotspots. The reviewer finds the single 70mm copper heat pipe useful where space is limited and active fans are not desirable. Installation is straightforward for anyone comfortable working inside a desktop or laptop, and the product's combination of copper and thermal fluid delivers quicker heat transfer than simple metal rods, making it a practical choice for modest cooling upgrades.

Key Features

• Copper construction: Solid copper body provides reliable thermal conduction from a heat source to a dissipation point.
• Thermal fluid core: The internal thermal fluid increases heat exchange responsiveness for faster hotspot reduction than plain metal alone.
• Compact size: At 70mm long and 4mm diameter the tube fits in tight spaces on GPUs, CPUs, laptop ICs, and LED modules where larger heatsinks cannot.
• Custom processing available: The seller offers bending and flattening on request, allowing the tube to be shaped for custom placements and contact surfaces.
• Passive operation: It works without fans, so it reduces moving parts and noise when paired with an appropriate radiator or backplate.

Who It's For

This copper heat pipe is aimed at PC builders, laptop repairers, and electronics hobbyists who need a simple, passive thermal bridge to move heat from a chip to a nearby heatsink or backplate. It is useful for targeted VRAM, RAM, or chipset cooling where adding a fan is impractical.

It is not a complete cooling system on its own and is less suitable for extreme overclocking or high-TDP CPUs and GPUs that require large vapor chambers or active cooling. Users who need full case airflow solutions or turnkey coolers should look elsewhere.

Pros & Cons

Pros

• Good thermal responsiveness from the combination of copper and thermal fluid for quicker heat transfer.
• Compact 4mm diameter and 70mm length fit into constrained spaces inside laptops and small desktops.
• Custom bending and flattening service allows tailored installation for a better contact surface.

Cons

• One-piece, passive design is not a standalone cooling solution for high-power CPUs or GPUs with heavy sustained loads.
• Limited length in the standard offering means multiple pipes or custom sizes may be needed for larger setups.

Our Verdict

The Bopaodao copper heat pipe is a practical, low-cost component for targeted passive cooling projects and small form-factor builds. It offers notably better heat transfer than plain copper bars because of the thermal fluid core and its small size and customization options make it good value for hobbyists and technicians who need a compact thermal bridge rather than a full active cooler.

Frequently Asked Questions

Can this pipe be bent to fit my layout?
Yes, the seller provides bending and flattening services if you message them with your requirements.

Is one piece enough for a GPU or CPU?
One 70mm pipe is suitable for small hotspot bridging but is not a replacement for a full active cooler on high-power CPUs or GPUs.

What is the main cooling advantage?
The combination of copper and thermal fluid improves thermal responsiveness and heat exchange compared with solid metal rods.
