GPU CPU Backplate Copper Heatsink Round Pipe 4mm x 80mm - Passive

In this review the reviewer examines a single-piece copper heat pipe intended for GPU and CPU backplate cooling, and recommends it to users who need a compact, passive thermal solution. The main reason to consider this item is its combination of pure copper construction and a thermal fluid core that claims much higher thermal conductivity than copper alone, making it useful where active fans are impractical. The reviewer installed and inspected the tube for fit and finish, and finds it best suited for targeted cooling of VRAM, RAM, chipset, and LED modules in tight spaces.

Key Features

• Material and build: Solid copper with a thermal fluid core gives improved heat transfer and a sturdy feel for reliable contact with small chips and modules.
• Compact size: The 4mm diameter and 80mm length make the tube easy to route inside laptops or compact PC builds where clearance is limited.
• Passive cooling: Designed to work without a fan, it provides quieter heat spread and can supplement existing heatsinks or backplates.
• Custom processing: The seller offers bending and flattening services so the pipe can be shaped to fit specific board layouts or radiator contacts.
• Versatile contact ends: The sharp end is intended for direct contact with a heat source while the smooth end transfers heat to a dissipation area or radiator connection.

Who It's For

This product is aimed at hobbyists and system builders who need a small, passive heat-transfer tube to improve thermal contact on VRAM, RAM, or chipset areas where space prevents larger solutions. It is also useful for repairs or custom cooling runs inside laptops and compact desktops where quiet operation and compact form are priorities.

Those who should look elsewhere include users expecting a full closed-loop liquid cooler performance or large-scale CPU/GPU cooling for extreme overclocking, since this single 4mm x 80mm tube is best used as a targeted thermal bridge rather than a primary cooler for high-wattage components.

Pros & Cons

Pros

• High thermal responsiveness from the thermal fluid core helps move heat quickly from small hotspots to a dissipation area.
• Compact 4mm diameter and 80mm length fit into cramped spaces and behind backplates with minimal modification.
• Custom bending and flattening services allow tailored installation for irregular layouts.
• Pure copper construction offers durable contact and good long-term corrosion resistance when used appropriately.

Cons

• As a single passive tube it provides limited total heat capacity and is not a replacement for full-size radiators in high-power systems.
• Installation requires careful contact and mounting; users may need thermal adhesive or clamps not included with the tube.

Our Verdict

The Bopaodao copper heat pipe is a practical, low-profile option for targeted passive cooling in tight builds; buy it if you need a durable 4mm x 80mm thermal bridge or a custom-shaped tube to transfer heat away from VRAM or chipset areas. It offers good value as a supplement to existing cooling, though it should not be relied on as the only cooler for high-wattage CPU or GPU loads.

Frequently Asked Questions

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

Is this intended to replace a fan or radiator?
No, it is a passive thermal tube meant to supplement cooling or bridge heat to a dissipation area; it is not a substitute for large radiators in high-power systems.

What surfaces should the sharp end contact?
The sharp end is designed for direct contact with small heat sources such as ICs, VRAM, or chipset pads while the smooth end transfers heat to a backplate or radiator connection.
