It can't because RP1 will be switched off, the GPIO will therefore no longer driven and low causes the fan to run at max-RPM if 5V is applied.
(Also replying to @dp11) — can someone confirm that setting POWER_OFF_ON_HALT=0 works for them? I have tried this on two IO Boards with two CM5, and in no case does the fan stay off—it always goes to 100% on power off, tested with multiple cycles. Am I insane, or does it just not work?
