Review: These are 100% actual heat pipes, not just copper tubes! - The heat travels down these heat pipes unbelievably fast! These are so cool to have on hand for demonstrations and experimenting with.
Review: Heat Pipe experiments! Wee! - I wanted to work on designing my own Raspberry Pi heat sink while designing my own RPi NAS case. To avoid all the clutter with hats interfering in that space I decided the best method would be to heat pipe the therms away from the processor to someone else in the case i could calmly (and quietly) dissipate it from. Somewhere where I could safely mount a big 120 mm fan... This pack let me experiment. The heat pipes worked great and with the help of a guide, i was able to bend them a bit and mount them on a head spreader on one end and a series of fins on the other. It worked out nicely and I recommend these to anyone wanting to experiment with heat pipes.

## Features

- It is suitable for the transformation and cooling of CPU, power supply, graphics card, etc.
- Replace the old copper pipes that come with the radiator to improve the heat dissipation performance.
- Size: 3x8x300mm/0.11x0.31x11.81inch

### ⭐⭐⭐⭐⭐ Copper pipes that makes it all cool!
*by M***R on July 2, 2025*

Why did you pick this product vs others?: I decided on this because I wanted better cooling for my system however I should have looked at how copper was ran first and did not. I can not replace what I have I just have to add to it. Build quality: These flat copper heat pipes are the real deal they absorb the heat really well. Functionality: They function as they should and dissipate the heat really well. I have also used then to keep hard drives cool too!
