A dozen 2018 Airs all overheat and reboot attempting internet recovery

Hey All!
So this is a weird one -- recently acquired from recycler a dozen 2018 Airs. All great shape, all power on, all wiped. However, when they attempt Internet Recovery, they sit there forever, and after an hour they overheat and reboot. I have also tried connecting to ethernet, and multiple Internet sources, so I know weak connection is not the problem.
These are not locked, but they have the default security utility setting for a 2018 which disallows booting from an external drive, so that is not an option. I have tried wiping in DFU mode, and that did not change anything.
Anyone have ideas? I keep thinking GPU issue, but very odd that a dozen machine would have exact same symptoms.
Also, look at this picture -- the progress bar looks weird. Never seen it like that, and they all look like that.
Thanks!
John
