PET-CF Cooling

When printing PET-CF I know you should have the part cooling fan off, and at ₃₀% for overhangs. But should the Aux fan be off as well?

I'd turn off all fans for regular printing, but still use 100% for steep overhangs and bridging.

I generally run ₄₀ mm/s for infill and walls. Less for small features.
