My Gotway/Begode EUC fan is pulsing?

On certain revisions of wheels, such as the MTen3 and MCM5 v2, Gotway/Begode has chosen to implement this fan behavior on purpose.

When the temperature is high enough, the fan will spin constantly, so there is no need for concern. In more recent batches, the fan behavior is updated such that the fans won't pulse at lower temperatures.
