GPU CPU Backplate Copper Heatsink Round Pipe 4mm x 300mm - Passive

In this review of the Bopaodao copper heatsink tube, the bottom line is simple: this is a compact, passive cooling component aimed at DIY system builders and repair technicians who need a slim, highly conductive heat transfer element. The review finds the product most useful for routing heat away from small hotspots on graphics cards, CPUs, laptop IC chipsets and LED modules where active fans are impractical. Its combination of solid copper and internal thermal fluid gives it a responsiveness and thermal conductivity advantage, making it a sensible choice when a thin, fanless solution is required.

Key Features

• Material: Solid copper with internal thermal fluid provides excellent heat conduction and rapid thermal response when attached to a hotspot.
• Dimensions: At 300mm length and 4mm diameter, it is long and thin enough to route in tight internal spaces and reach a remote heatsink or backplate.
• Passive operation: Works without additional power or fans, so it adds no noise and suits fanless or low-noise builds.
• Custom processing: The manufacturer offers bending and flattening services, enabling custom shapes to match specific mounting layouts.
• Versatile use: Designed to pair with graphics card radiators, CPU backplates, laptop IC chipsets and LED modules needing localized heat spread.

Who It's For

The heatsink tube is best for hobbyists, system builders and repair technicians who need a discreet, passive thermal link to move heat from a concentrated source to an existing radiator or backplate. It is also useful for laptop repairs where space is tight and a thin, bendable tube can redirect heat away from sensitive components.

Users who want an all-in-one active cooler or who need large-scale cooling for high-TDP desktop CPUs or GPUs should look elsewhere; this component is a targeted thermal bridge rather than a full replacement for large air or liquid coolers.

Pros & Cons

Pros

• High thermal responsiveness due to copper construction and internal thermal fluid, improving heat transfer from hotspots.
• Thin 4mm diameter and 300mm length make it flexible to route inside compact builds or laptops.
• Passive, fanless operation keeps systems silent and requires no power or controls.
• Custom bending and flattening options let you fit unusual layouts or specific installation needs.

Cons

• Not a complete cooling solution for high-TDP components; best used as a supplemental heat pipe to an existing radiator.
• Installation requires careful contact at the sharp heat source end and secure mounting to the dissipation end for effective performance.

Our Verdict

The Bopaodao 4mm x 300mm copper heatsink tube is a practical, low-cost option for routing heat in cramped builds or repairing laptop thermal paths. It delivers excellent passive heat transfer for targeted hotspots and is good value when used as a supplemental heat bridge to an existing radiator or backplate.

Frequently Asked Questions

Can this tube be bent to fit a custom layout?
Yes, the seller offers bending and flattening processing; contact them with your requirements for custom shaping.

Will this replace a CPU or GPU fan cooler?
No, this tube is intended as a passive heat transfer element to assist a radiator or backplate, not as a full active cooling replacement for high-TDP cooling needs.

Is it suitable for laptop chipset cooling?
Yes, its thin 4mm profile and passive operation make it suitable for directing heat away from laptop IC chipsets and tight component zones.
