Iirc the way they got around the rules with the fan car was by directing more than 50% of the fan’s airflow into cooling, therefore the fan’s predominate use was for cooling and any aero advantages it gave was just an ‘unintended’ consequence.
Still moveable aero. At the risk of going off subject, that car was originally designed to have surface mount radiators. When it was found that bad math had been used and this was impossible, Gordon Murray under a time crunch, put the fan on. But, he knew full well what it would do to ground effects.
