Anyone make their own heatsink before?

Ok, I currently dont have a job but my CPU needs a new cooler. What I do have is a soldering gun, solder, and a whole lot of Aluminum and copper(I scrap metal on the side).

I was wondering if anyone has made their own Heatsinks and if they could dive me any tips.



Would it be more effective if I soldered some Copper pipes to my current Ruby Orb heatsink that has a 80mm fan on it?

... if you have a whole lot of copper then you have enough to sell and buy a factory heat sink with heat pipes that will far surpass anything you could hope to build without a financially backed R&D dept or a huge fricken brain.

Well I got to pay Auto Insurance with most of that money, lol. I can take some of it out though as a pound or two wont make a difference.

Also, making one will give me something to do.

It is pretty tough to make your own air cooled heatsink that is effective, unless you have access to and know how to work with heatpipes. The reason is that heat doesn't travel through metal very efficiently, and thus the typical thin aluminum/copper fins lose much of their effectiveness after an inch or two. You can put fins closer together, but would need a more powerful fan to push air through. Make fins longer and you need heatpipes or another method of moving heat farther along the fins.

So this basically means that I would have to make up for the lack of heatpipes with a larger number of short fins if I were to make one?


If I need to I might be able to desolder 1 or 2 heatpipes of an old outdated heatsink.

sure you can do it.

the main thing is, the heat-sink surface next to the CPU lid needs to -
* be flat
* make a good pressure contact with the top of the CPU.

i've designed a lot of wierd heatsinks & had them fabbed, but not for a PC.
