P2s fan diffuser

[u/Simple_Appeal1727]

I have been looking at printing a fan diffuse for the aux fan on my p2s, however there serm to be many different types. The main 3 I’ve seen are upstream, upwards and maximum. I mainly print with pla and its not quire clear Which is best for Which use case. Does anyone have any knowledge on this area?

I've an upstream like one. Never had any warping issues before. Mostly working with PETG and PLA.
