It does that yes, but no, you can't change it easily. It's a self-test function performed by the on-board MCU, so the firmware has to be changed for that to happen.A daughterboard that circumvents this problem would be quite ambitious. While the fan is indeed connected by a header, it's a 4pin one, so you would first have to fake the feedback signal that the MCU uses to read the actual RPM of the fan. Not something I'd want to dip my toes in, to be quite honest.
