Cool Down Your Raspberry Pi With an Old Computer Fan
The Raspberry Pi usually runs pretty cool and you don’t need a fan, but if you’re overclocking it or running something particularly intense, it’s useful. Don’t look for any specialized fan, however, as YouTuber NetHacker points out, any old computer fan will do.
NetHacker pulled the fan out of the unneeded computer, plugged it into the Pi’s GPIO, and it was up and running right away. If you have an older computer, it probably has a fan that will do the job just fine. If not, you can usually buy it for a couple of dollars.
