GPU CPU Backplate Copper Heatsink Round Pipe 5mm x 280mm - Fanless

In this review the GPU CPU Backplate Copper Heatsink Round Pipe from Bopaodao is evaluated as a small, serviceable passive cooling option for specific DIY fixes and upgrades. Its single biggest selling point is simple: a 5mm copper tube filled with thermal fluid that conducts and transfers heat efficiently without a fan. For users seeking a compact, fanless heat spreader to augment graphics card backplates, chipset cooling, or laptop IC hotspots, this heatsink tube offers a direct, low-profile way to move heat to an external radiator or larger dissipation area.

Key Features

• Material and construction: Copper body with thermal fluid provides strong heat conduction and fast thermal responsiveness for targeted cooling.
• Size: 280mm length and 5mm diameter make it long enough for many backplate or radiator runs while remaining discreet in small builds.
• Passive operation: Works without a fan, making it useful for silent setups and areas where airflow is limited.
• Custom processing: The seller offers bending and flattening services so the tube can be shaped to fit specific layouts and contact points.
• Versatile application: Designed for GPU/CPU backplates, laptop IC chipsets and high-heat LED modules where space is tight.
• Sharp-to-smooth ends: Narrow end designed to contact heat source and smooth end intended for heat dissipation into a radiator or plate.

Who It's For

This product is for tinkerers, system builders, and repair technicians who need a thin, passive thermal tube to bridge a hotspot to a heatsink, backplate, or external radiator. It is especially appropriate when silence matters or where small-profile cooling is required inside laptops, compact PCs, or LED assemblies.

It is not targeted at users who expect a complete cooling kit or plug-and-play air coolers; those needing large-scale active cooling or full compatibility guarantees for every board should look for integrated heatsink assemblies instead.

Pros & Cons

Pros

• Highly conductive copper with thermal fluid offers fast heat transfer for a compact tube.
• Long 280mm length provides flexibility in routing and contacting multiple dissipation areas.
• Custom bending and flattening service allows fitting to nonstandard layouts.
• Fanless design supports quiet operation in noise-sensitive builds.

Cons

• Limited diameter of 5mm may restrict raw heat capacity compared with larger heat pipes or full heatsinks.
• Requires user skill to install and pair with a radiator or backplate for effective dissipation.

Specifications

Our Verdict

The Bopaodao copper heatsink tube is a practical, low-profile solution for targeted passive cooling where space and noise are constraints. It delivers good thermal responsiveness for its size and the customization option makes it adaptable to odd layouts. Buyers who need higher capacity cooling or a full active cooler should consider larger alternatives, but for silent, bespoke routing to a radiator this tube is good value.

Frequently Asked Questions

Can this tube be bent to fit my board?
Yes, the seller offers bending and flattening processing by request to match specific layouts.

Is this a complete cooling kit?
No, it is a passive copper tube intended to be connected to a radiator or backplate; it does not include mounting brackets or fans.

Will it work in a laptop?
It can be used for laptop IC chipsets where space allows, but careful installation is required to ensure proper contact and routing.
