This is almost an accidental instructable - my son was taking apart a computer fan for a different project, my eye fell on the heatsink and I had a lightbulb moment...
Step 1: Materials & Tools
This candlestick is made from a retired PC fan, and that's all you really need in the way of materials.
The tools are almost as basic - all I used was my multi-tool. If you haven't got a multi-tool, then you'll need a small screwdriver (probably a cross-head) and a pair of pliers.
Step 2: Disassembly
This instructable is not so much a make as an unmake - most of the work is in disassembling the PC fan and the frame that holds the fan to the heatsink.
I started by unclipping the fan itself from the frame.
Four small screws released the frame from the heatsink, and then a quick wrench with the pliers removed the plastic widgets that presumably held the fan in place in the PC case.
This left me with a copper bowl, surrounded by aluminium vanes, and all atop four dinky little feet.
Step 3: Wash!
Once the heatsink was released from its bonds, it turned out to be full of fluff and dust.
A quick rinse in hot water fixed that, and once it was dry I could call the candlestick finished.
Step 4: Display
I actually had several identical PC fans, so I made a second candlestick, and I now have a pair, one at each end of the mantelpiece.
If you're not stopping to take photos, this whole project only takes a few minutes, so keep an eye on the tech scrap you collect in your stash - some of it is more decorative than you think!
