GPU CPU Backplate Copper Heatsink Round Pipe 4mm x 170mm - Passive

In this review of the GPU CPU Backplate Copper Heatsink Round Pipe, the bottom line is simple: this single 170mm copper heat pipe is best for hobbyists and technicians who need a compact, passive cooling solution for graphics cards, CPUs, laptop ICs or LED modules. The reviewer found the product stands out because its copper construction combined with a high-performance thermal fluid promises rapid heat transfer without a fan, making it a practical option when space or noise constraints rule out active cooling. It is not a full cooler but a focused thermal bridge for targeted heat dissipation.

Key Features

• Pure copper construction: Copper body gives reliable conductive heat transfer and durable contact with hot components.
• Thermal fluid inside: The internal thermal fluid acts as a heat exchange medium to move heat away from the source faster than metal conduction alone.
• 170mm length, 4mm diameter: The compact 170mm length and slim 4mm diameter make it suitable for tight spaces in laptops and compact PC builds.
• Bend and flatten service: Custom bending and flattening services allow modification to fit nonstandard layouts or to increase contact surface area.
• Passive, fanless operation: Designed to work without active fans, it reduces noise and adds cooling where conventional heatsinks are impractical.
• Sharp-to-smooth design: The pointed contact end concentrates heat pickup while the smooth end improves heat dissipation to attached radiators.

Who It's For

Technicians, modders and system builders who need a targeted passive heatsink or a heat bridge for a graphics card, CPU backplate, laptop IC chipset or LED module will find this product useful. Its small diameter and long length suit cramped layouts and custom routing where a full heat pipe assembly would not fit.

Users seeking an out-of-the-box complete cooling system, a replacement for a full-size cooler, or plug-and-play compatibility with a specific consumer laptop model should look elsewhere. This is a single heat pipe intended as a component for custom cooling work rather than a finished cooling assembly.

Pros & Cons

Pros

• Compact copper tube carries heat effectively and fits into narrow gaps where larger heatsinks cannot.
• Internal thermal fluid boosts heat transport beyond simple metal conduction for quicker response to temperature changes.
• Customization services for bending and flattening let installers form the pipe to match unusual layouts.
• Fanless operation reduces noise and adds a passive cooling option for silent builds.

Cons

• Sold as a single pipe rather than a complete cooler, it requires user skill to integrate with existing radiators or backplates.
• Fixed diameter and length choices mean users may need custom processing for some applications.

Our Verdict

For DIY builders and repair technicians this 4mm x 170mm copper heat pipe offers a compact, effective passive cooling option that improves targeted heat transfer without added noise. It is good value as a component for custom cooling projects thanks to its thermal fluid core and available bending services, but it is not a substitute for a complete cooling assembly.

Frequently Asked Questions

Can this pipe be bent to fit my layout?
Yes, the seller offers bending and flattening processing services to shape the pipe to your requirements if you request custom work.

Is this a complete cooler or a single component?
This item is a single copper heat pipe intended as a component to connect to radiators or backplates, not a full, standalone cooling system.

What sizes are available?
Diameters range from 4mm to 50mm and lengths range from 50mm to 520mm according to the product options and custom offerings.
