Flat Heat Pipe 3.5mm x 11mm x 200mm Copper Heatsink Pipe - Thin

In this review the focus is on a single-purpose thermal component intended for DIY cooling projects and compact electronics. The Flat Heat Pipe from Bopaodao is a simple, thin copper tube designed to move heat away from chips in laptops, phones, GPUs and RAM modules; the single biggest reason to buy is its high copper content and long, flat profile which make it useful where space is limited and a fanless solution is preferred. The review explains where this pipe fits in a cooling mod and what to expect during fitting and use.

Key Features

• Pure copper construction: Made of 99% pure copper to provide good thermal conductivity and more efficient heat transfer than plated or alloy alternatives.
• Thin, flat profile: At about 3.5mm thick and 11mm wide the pipe can slip into tight gaps between components for low-profile, fanless cooling setups.
• Long length: The 200mm length allows routing from a heat source to a distant radiator or backplate, enabling flexible layouts in laptops and custom rigs.
• Customizable shape: The seller offers bending and flattening services so the pipe can be shaped to fit a specific chassis or component layout.
• Tolerances noted: Thickness may vary by around 0.2mm and length by about 0.5mm, so installers should allow for small dimensional variance during fitting.

Who It's For

This product is for hobbyists and technicians who build or modify compact cooling systems for notebooks, small form factor PCs, or mobile device prototypes and who need a thin, long, high-conductivity thermal path. It is particularly useful when space prevents the use of bulkier heat pipes or when a passive, fanless approach is desired.

It is not aimed at casual users who want a plug-and-play cooler; installation requires basic soldering or mechanical mounting skills and an understanding of thermal routing. If you need active cooling with integrated fans, or a drop-in cooler with mounting brackets for a specific CPU socket, look elsewhere.

Pros & Cons

Pros

• Very high copper content provides effective heat dispersion for small hot spots.
• Low-profile flat shape fits narrow spaces inside laptops and slim enclosures.
• Long 200mm length gives flexibility in routing to backplates or external radiators.
• Seller customization options for bending and flattening help fit unusual layouts.

Cons

• Requires manual fitting and thermal interface work; not a drop-in consumer product.
• Small dimensional deviations are possible, so precise fits may need adjustment.

Our Verdict

For DIYers and technicians needing a compact, high-conductivity thermal bridge, this flat copper heat pipe is a practical and cost-effective choice. Its thin profile and 200mm reach make it particularly valuable in laptop and small PC modding where space is tight, and the available shaping service adds real installation flexibility. Expect to invest a little time in fitting, but the material and length deliver solid passive cooling value.

Frequently Asked Questions

Can this be bent to fit a custom layout?
Yes, the seller offers bending and flattening services and can process the pipe to shape if you request it before purchase.

Is the copper pure and suitable for heat transfer?
Yes, the pipe is described as made of about 99% pure copper to provide effective heat dispersion for chips.

Will it replace a fan-based cooler?
No, this is best used as a passive thermal bridge or part of a hybrid system; it does not provide active airflow and may not be sufficient alone for high-power CPUs or GPUs.
