Flat Heat Pipe Copper 3.5mm x 11mm x 50mm GPU CPU Heatsink - Thin

Our review finds the Flat Heat Pipe from Bopaodao is a simple, low-profile thermal solution best suited for DIY cooling projects and tight laptop or small-form PC spaces where a thin, passive component is needed. In this review the biggest reason to consider it is its nearly pure copper construction which gives it strong thermal conductivity in a compact 1.97in length and 0.14in thickness, so it can shuttle heat from a chip to a backplate or heatsink without adding a fan or much bulk. It is a component part rather than a complete cooler, intended for modders and technicians who need a reliable thermal tube.

Key Features

• Compact dimensions: The 3.5mm x 11mm x 50mm size fits narrow gaps inside laptops and small PCs where larger heat pipes will not.
• High copper content: Made from 99% pure copper to provide effective heat dispersion from CPU, GPU, VRAM or RAM to an external sink.
• Thin profile: At about 0.14in thick this heat pipe is suited for fanless and low-clearance builds that require minimal added height.
• DIY friendly: It is intended to be connected to existing radiators or backplates to improve overall heat dissipation in a custom cooling setup.
• Custom shaping available: The seller offers bending and flattening services on request so it can be adjusted to specific routing or contact requirements.

Who It's For

This component is ideal for technicians, hobbyist modders, and users repairing or upgrading laptop and small PC cooling who need a short, flat copper heat pipe to bridge a hotspot to a heatsink or backplate. It works well when a passive, low-profile solution is preferred and there is room to attach or mate it to an existing radiator.

It is not a complete cooling system, so casual users looking for a drop-in fan or full replacement cooler should look elsewhere. Also, those who require precision-manufactured, pre-bent heat pipes for mass production may prefer factory-formed assemblies rather than ordering a single piece.

Pros & Cons

Pros

• High-purity copper gives efficient thermal transfer for short conduction runs.
• Very thin and compact, suitable for tight internal spaces and fanless designs.
• Custom bending and flattening service allows adaptation to specific layouts.

Cons

• Sold as a single piece component, so additional parts or mounting hardware are required to complete a cooling solution.
• Small dimensional deviations are possible in thickness and length, which can affect very tight tolerances.

Specifications

Our Verdict

The Flat Heat Pipe is a practical, low-cost component for anyone building or repairing compact cooling systems where space is limited. Its near-pure copper construction and thin profile make it good value for targeted heat bridging, provided the buyer understands they are purchasing a single part that must be integrated into a larger cooling solution.

Frequently Asked Questions

Can this heat pipe be bent to fit my layout?
Yes, the seller offers bending and flattening services; contact them with your requirements so they can process the part accordingly.

Will this replace a laptop fan?
No, this is a passive heat pipe component meant to conduct heat to a heatsink or backplate and is not a full fan replacement on its own.

Are the dimensions exact?
Dimensions are nominal with stated tolerances: thickness may vary by about 0.2mm and length by about 0.5mm, so allow for small deviations.
