I recently upgraded my Home Assistant Yellow from a CM4 to a CM5 (It's remarkably easy), but I found it was difficult to keep it cool enough. Since I didn't find an existing design that met my needs, I decided to make one.

⚠ Warning about the fan: I used a 12v fan since I had CRJ headers laying around. You could just as easily use a 5v fan and the existing headers on the board (see the attached photos). Detailed board schematics can be found on HA's github. I used kicanvas to make verifying the files easier (link)

Hardware required

  • M3 x D5 x L4 heat set inserts (qty: 8)
  • M3 x 6 mm countersunk screws (qty: 4)
  • A 40 mm x 10 mm fan
  • PC fan screws (qty: 4)

Step and Fusion 360 files included. I printed my case in PCCF just for fun. PLA or PETG would probably be fine.
