Simple Extensible backplate replacement

[bored99]

Finally put my pondering into action….
With the new AIO and expansions board by @vileer , i have decided to take the plunge to upgrade to a CM5. To accommodate the heat sink i am planning to install, i’ve come up with a single plate cut-out design with access to the battery compartment.
The battery cover will be plastic with magnetic attachments so as to have quick access as well as better wireless signal penetration over the back plate. Especially when a wireless module is used on the USB-C internal connector. IMHO, this method is low cost and effective.

Current testing with CM4 seems to suggest that temperature can remain between 40-60 degC once i attach a heat sink in place.

Got my CM5 and heat sink. Printed up a cover to test. Seems to be working pretty well. As I haven’t recieved the new board from vileer, I’m powering the active fan externally for now.

normal workload has the unit going at about 40-51deg. It has not gone more than 55deg yet. My ambient temperature is 32-36deg so that’s pretty good.

rear enclosure is 3D printed PLA. Not great, but works for now. Have a better nylon print in the way with better temperature characteristics.

Will share more as I get more set up.
