Here is a neat way of repurposing old CPU heatsinks from various broken, tired, or otherwise obsolete desktop PCs; using them as stands and holders for documents, leaflets, business cards, notes, stationery and other small items!
CPU heatsinks are typically designed in a way that maximises the surface area so that as much heat can be drawn away from the heatsink as possible. Due to that design, they come in quite handy for more than just drawing heat away from processors and therefore keeping them nice and cool.
I salvaged a total of three CPU heatsinks from some old desktop PCs that were kept in the store room, and cleaned them up by removing the old thermal compound from underneath the heatsinks and removing as much dust from in between the fins as possible. Two of the heatsinks are seen in the above photo taken during the Sheffield Community Toolbank relaunch event.
As you can see from the photo, the rectangular heatsink makes for quite a nice holder for forms, leaflets, notes, and other small documents, while the circular heatsink has a recess in the centre that makes it useful for holding pencils, pens and other small items of stationery. Chipset heatsinks can also be used for this purpose as well; their diminutive size makes them useful for smaller items like business cards, shopping lists, tags and labels.
So rather than simply discard the old heatsinks along with the rest of the parts inside the computers, why not take them out of the computers, clean them up, and use them as stands and holders? A computer part that gets reused and repurposed for something useful, means one less item meeting its end in landfill!
