How to choose the right one
-
Match your component type
You must verify the compatible device before purchasing. These heatsinks are designed for GPUs, laptops, and RAM modules, not standard CPU sockets. The Bopaodao 140mm Copper Heat Pipe works well for extending heat from VRAM or chipsets. Ensure the base fits your specific component shape. Using a passive pipe on a standard CPU socket will not provide adequate cooling. You need a dedicated fan and proper mounting for these specialized parts.
-
Prioritize copper material
Both options in this guide use copper construction. Copper conducts heat more effectively than aluminum alternatives. This material choice helps spread thermal energy from hot spots to a larger surface area. You benefit from faster heat transfer rates with copper pipes. The Bopaodao model leverages this property to move heat away from sensitive electronics. If you need efficient passive cooling, copper is the superior material choice for your setup.
-
Plan for fan integration
These products are passive cooling solutions. They do not include fans. You must attach your own 140mm fan to complete the cooling setup. This gives you control over airflow and noise levels. Ensure your case has space for a 140mm fan. The heatsink relies on your fan to move air across the copper pipes. Without active airflow, the passive design cannot dissipate heat effectively. Check your case compatibility before buying.
-
Consider size constraints
The Bopaodao 140mm Copper Heat Pipe measures 140mm in length. This dimension determines how much surface area you have for heat dissipation. The diameter is 8mm, which targets specific hot spots. You need enough clearance in your system to accommodate this length. Larger sizes spread heat over a wider area. Smaller diameters focus heat transfer on precise components like VRAM. Measure your available space before selecting a size.
-
Evaluate targeted cooling needs
Determine if you need general heat spreading or targeted cooling. The Bopaodao model excels at extending heat from small components like GPUs or chipsets. If you have hot spots on a motherboard or graphics card, this passive pipe helps. It moves thermal energy away from the source. You do not need this for entire CPU cooling. Use it where specific components generate concentrated heat. This specialized approach complements your main cooling system.
Frequently asked questions
Do these heatsinks come with a fan included?
No, these units are passive copper pipes. You must attach your own 140mm fan to complete the cooling setup. The products listed are designed solely for heat extension. They rely on external airflow to dissipate heat effectively. This allows you to choose a fan that matches your specific noise and performance needs.
Are these compatible with standard CPU sockets?
No, these heatsinks are not designed for standard CPU sockets. They are compatible with GPUs, laptops, and RAM modules. Their purpose is to extend heat spread from hot components to a larger area. You should verify the compatible device type before purchasing to ensure proper fit and function for your specific hardware.
What material are these heat pipes made of?
Both listed options use copper construction. Copper conducts heat more effectively than aluminum, making it ideal for moving thermal energy away from hot components. This material choice ensures efficient heat transfer from sources like VRAM or chipsets to the area where your 140mm fan will provide airflow.
How long are the copper heat pipes?
The primary model features a length of 140mm. This dimension allows for significant heat spread from the source component to a cooler area. The diameter is 8mm, providing a compact profile for targeted cooling. This size helps fit within various chassis layouts while extending thermal dissipation effectively.
Can I use these for VRAM cooling?
Yes, these are suitable for targeted VRAM cooling. They are designed to extend heat dissipation from small components like VRAM or chipsets to a cooler area. By attaching a 140mm fan, you can actively cool the extended copper pipe, helping to maintain lower temperatures for your memory modules during intensive tasks.
What is the difference between the two models?
The first model is rated as the best overall for general heat spread extension. The second is labeled as also great for targeted VRAM or chipset cooling. Both share the same 140mm length and 8mm diameter. The distinction lies in their recommended application focus, though the physical specifications remain consistent across both options.
