Hello,

Does implementing the fan curve (in 3D Fan Zone) as piece-wise linear as opposed to linear increase the computational time? User guide does not mention anything about it.

Regards,
Yanki

Not really. The difference is negligible.

It just takes more time for a human to setup.


In rare instances you can run into stability or divergence problems, but that's not directly related to computational cost.
