Thanks, people keep calling it RNG when it's actually the literal opposite of random.
The fan moves at a predictable and reliable speed. It's a constant. Just like the bars.
The only random things on this level are which platforms will fall, and the actions of other players. Both of these things have always been in this level.
Timing out is not supposed to be how finals end. That was just added to ensure that matches don't continue for ridiculous amounts of time.
If people were timing out often - it means that the round was too easy.
