## Description

Product description Flat Heat Pipe Computer Tube 0.3x0.8x8cm Copper Sink CPU Tube Retrofit

Review: Seem to work - I dont really have the tools to check how well they conduct heat, but they seem to be working as expected for me
Review: Small straight copper heat pipes, interesting to experiment with - I was given a sample of these heat pipes to review. I build hot air engines as a hobby, and I haven't yet figured out how to employ one there, but I'm certainly interested in thinking about the possibilities. In the meantime it's fun to experiment with these, even bringing near to a candle (while holding in pliers of course), and measuring an end with a non-contact digital thermometer. Or with an ice cube, and noting the difference in performance. The speed of heat transfer is remarkable. These demonstrate well why heat pipes are used in space vehicle and computer cooling. They are reasonable enough in price to experiment with. They have a small straight form factor useful for a model experiment. They appear to be pure copper, mine were not adhesive backed like a computer IC cooler, so they do need a mechanical support. Never try to hold one if you are doing a heat experiment, and stay within the temperature limits of water vapor filled heat pipe (I assume), if you are going to experiment.

## Features

- Size:8x0.8x0.3cm/3.14x0.31x0.11Inch(LxWxT)
- Material:Made of copper material,provide good quality for long time service.
- Easy application,ideal part for Electronic computer accessory part. The sharp end of the heat pipe is in contact with the heat source, and the smooth end is the heat dissipation end
- Good to retrofit for CPU Heatsink,Power South Bridge North Bridge ,MOS Tube Heatsink and Graphics Card.
- Can be connected to the phone computer graphics card CPU GPU radiator to improve the phone computer’s heat dissipation capacity

### ⭐⭐ Contains lead
*by D***N on November 20, 2024*

Works well. I tested it for lead and it came out positive. Not a big deal if you're gonna put it in your computer as a heat sink. But if you want to play with it, especially if you're letting kids play with it or using it to cool down food, get a different brand.
