I needed a cheap heatsink for my Raspberry Pi 3 that I use as a music player/server. To maximize performance, I wanted to overclock the computer for faster searching and handling of all my music. I’ve managed to overclock my central Stratum-1 NTP server to 1350MHz without any problems, but the dinky little aluminum heatsink was way to anemic, so I found a very cheap DIY solution to my problem. With this heatsink, I can run the Raspberry Pi 3 at 1.5GHz all day at full tilt without any issues!
