GPU CPU Backplate Copper Heatsink Round Pipe 5mm x 130mm - Passive

In this review the reviewer examines a single-piece copper heat pipe intended for improving passive cooling on graphics cards, CPUs and compact electronics. The bottom line: this compact 5mm x 130mm copper tube is for DIY modders and technicians who need a simple, high-conductivity thermal path without fans. It excels when added to a backplate, small radiator or hotspot on a laptop IC because the construction uses copper plus a thermal fluid to move heat away quickly, and the tube can be bent or flattened to match the contact surface.

Key Features

• Material and construction: Solid copper with an internal thermal fluid provides a combination of conduction and phase-change heat transfer for faster response to temperature spikes.
• Size: The 130mm length and 5mm diameter make it easy to route inside desktops and some laptop service areas without crowding other components.
• Passive operation: It is a fanless solution that reduces noise while supplementing existing cooling by transporting heat to a dedicated dissipation area.
• Customizable shape: The seller offers bending and flattening services so the tube can be formed to match a GPU backplate, RAM heatsink or LED module for better contact.
• Versatile application: Usable with desktop GPU/CPU radiators, laptop IC chipsets and LED modules where extra thermal capacity is required.
• Thermal responsiveness: The combination of copper and thermal fluid is designed for rapid heat exchange, improving transient cooling behavior compared with plain metal alone.

Who It's For

This part is best for DIY system builders, repair technicians and modders who are comfortable modifying internal components and who want a passive, low-noise way to move heat from a hotspot to an existing heat sink or backplate. It is also useful for small electronics projects where space is limited but extra thermal conductivity helps reliability.

It is not intended for users who expect a standalone cooling solution or complete thermal management without additional heatsinks or mounting hardware. If you need plug-and-play active cooling or a complete cooler assembly, look elsewhere for a finished product.

Pros & Cons

Pros

• High thermal responsiveness from the copper plus internal thermal fluid improves transient heat transfer.
• Compact 130mm length and 5mm diameter fit many tight internal layouts and allow discreet routing.
• Bending and flattening services let you tailor the tube to specific contact surfaces for better results.

Cons

• Requires additional heatsink surfaces or mounting to be effective; not a complete cooling assembly by itself.
• Installation requires care to ensure proper contact and avoid damage to surrounding components.

Our Verdict

This copper heat pipe is a practical, low-cost component for anyone wanting to boost passive cooling on GPUs, CPUs or tight laptop hotspots. It delivers good thermal responsiveness and is especially useful when you can customize the shape to improve contact; however, it must be integrated with existing heatsinks or radiators to be effective, so it suits modders and technicians rather than end users seeking turnkey coolers.

Frequently Asked Questions

Can this be mounted directly onto a GPU or CPU?
It can be used to link a hotspot to a heatsink or backplate, but you need proper thermal interface material and a secure mounting method; it is not a drop-in replacement for a full cooler.

Is the tube available in other sizes?
The seller notes diameters from 4mm to 50mm and lengths from 50mm to 520mm are offered for different needs.

Can the tube be bent to match my component?
Yes, bending and flattening services are available; contact the seller with your requirements before ordering for custom processing.
