CrowPi2 RPi overheat ‘lightning bolt’
I get the overheat lightning bolt often, even though the CPU sensor never reads over 44C, until I remove the keyboard, then it is fine.
so thought I would add some low profile 5mm copper hearsinks, just in case.
There is no clearance to the fan holder.
Would it be OK if I (remove all electronics from case and) cut some of this plastic away to fit the heatsinks?
Looks like plenty of distance to the fan, just the housing in the way.

I guess the ‘Lightning bolt’ is actually the under voltage warning on the R Pi4. Not sure what to do about that at the 5 volt power on the CrowPi2 comes off the 24 watt 12 volt power supply.
Maybe something wrong with the internal voltage regulator in the CrowPi2?
Finally found my answer in the CrowPi2 FAQs: normal.
