My current solution for the CM5. I wired a waveshare heatsink and fan to the the spare usb pinout of the sdr board. I also added a switch so i can control when it runs. It brings it back down to 33-35 in about a minute. I had to cut open the back for heat sink clearance.

That’s a nifty solution. How does it affect battery life? I guess if you’re only switching the fan on when needed, not so much?
Love the hexbolts!!
I wish the uConsole could run on an M2 rather than SD card. The 2230 you have installed is interesting. Is that something you built yourself or was the internal USB port part of the expansion board?
Sorry, loads of questions 
The 2230 board is this one from Amazon. You will need a usb-c extension or the board interferes with the back panel.
As far as power… the switch helps it be a minimal draw. I could see if there wasn’t a switch it would be noticeable on its battery life consumption.

Great idea to use this, thanks for the link.
Oh wow I like this so much better than trying to mount a blower fan next to the heat sink!
Where did you get that switch if you don’t mind sharing?
I got them from Amazon.

Awesome thanks ordered!
You’ll need to ream out the antenna hole slightly and bend the switch pins to clear the board.
Thanks for the heads up. I have a dremel so should be fine.
Without the adapter board between the main board and the carrier board for the cm5, what is the displacement distance between Cm5 and the inside of the metal back panel?
This probably isn’t the answer you’re looking for, but this aluminum block from @lululvlv covers the gap between a CM4 or CM5 and the back plate without a gap. You might try asking Lulu if they can send you the measurements.
