GPU CPU Backplate Copper Heatsink Round Pipe 4mm x 150mm - Passive

In this review of the GPU CPU Backplate Copper Heatsink Round Pipe from Bopaodao the bottom line is simple: this is a compact, passive cooling element aimed at hobbyists and system builders who need targeted, fanless heat transfer. The reviewer found the 150mm length and 4mm diameter tube useful for routing heat from small hot spots such as GPU VRAM, CPU backplates, laptop ICs and LED modules, and the combination of copper and internal thermal fluid delivers noticeably better responsiveness than a plain metal rod. It is best appreciated by those comfortable doing minor installation and bending work rather than users seeking a drop-in consumer accessory.

Key Features

• Copper construction: Solid copper body gives reliable thermal conduction and durable contact with heat sources.
• Thermal fluid inside: The internal fluid acts as a heat exchange medium so the tube moves heat more effectively than metal alone.
• 150mm length and 4mm diameter: This size is compact enough for laptop or tight PC cases while still providing a useful thermal path between components.
• Bend and flatten services: The seller offers bending and flattening processing so the tube can be shaped to fit custom installations.
• Fanless passive cooling: Designed to connect to existing radiators or dissipative surfaces to improve cooling without adding noise.

Who It's For

This product is best for DIY PC builders, repair technicians, and modders who need a small, passive copper heat pipe to shuttle heat from a hot spot to a heat sink or chassis surface. It suits projects where space is limited and added fans are undesirable, such as laptop chipset repairs or compact GPU backplate upgrades.

It is less suitable for users wanting a complete plug-and-play cooler or those who cannot perform simple mechanical shaping and installation; large-scale CPU or GPU cooling for high TDP parts will require full heatpipes or active cooling solutions instead.

Pros & Cons

Pros

• Solid copper and thermal fluid construction provides efficient, responsive heat transfer for small hot spots.
• Compact 4mm diameter and 150mm length fit tight spaces and can be routed where larger pipes cannot.
• Optional bending and flattening services allow customization for a cleaner installation and better contact.

Cons

• Not a full cooling system on its own; it requires integration with a heatsink or chassis to dissipate heat effectively.
• Installation and shaping may require tools and some mechanical skill, which may deter casual users.

Our Verdict

The Bopaodao copper heatsink tube is a practical, low-cost component for targeted, passive heat transfer in compact systems. Builders who need to move heat from small chips or backplates without adding fans will find its copper body and internal thermal fluid effective and customizable, making it a good value when integrated with a proper dissipation surface.

Frequently Asked Questions

Can this tube be bent to fit my layout?
The seller provides bending and flattening services, and the tube can also be shaped carefully by the installer to match routing needs.

Will this replace a CPU cooler?
No, this tube is intended as a passive heat transfer element to connect a hot spot to a heatsink or chassis and is not a standalone CPU cooler for high TDP processors.

What sizes are available?
Diameters range from 4mm to 50mm and lengths from 50mm to 520mm, with the reviewed unit at 4mm x 150mm.
