I took a Pi3 and put it into the official case. Nothing special about that, except they get hot, very hot. First thing was to add a copper heatsink which was enough for the Pi2. Unfortunately not so for a Pi3 running flat out. Time to add a fan.
I used a 40mm Noctua as they are only 17dB. You can hardly hear it running. Its a BOINC number cruncher running 24/7 so I wanted something reliable.
If you want to see how it got to this point there are more pictures at http://markjatboinc.blogspot.com.au/201 ... -case.html
