I've seen reports that the rpi3B cannot go beyond 600Mhz without
heatsinks because of thermal throttling. I've ordered a case kit (with
heat sinks) to test this for myself.
I'm actually kind of impressed - the board is absolutely stable with
no additional trappings, and at 600Mhz essentially runs like the XO-1.
Add heat syncs, and (according to these reports from people running
Fedora 29), clock jumps to 1.4Ghz on demand (and power consumption jumps
as well) and dnf no longer feels like molasses. That is true hardware
flexibility.
