Help printing Prusament PLA Blend

I've been trying to print a Benchy for my Benchy collection, but i cannot figure this filament out.

I've tried temperatures ranging from 190 to 225 and i can barely even tell them apart, because the overhangs look crappy on all of them.

Does anyone have print settings for this type of filament?

225°:

215°:

205°:

190°:

215° 0.1mm 50% Speed:

Galaxy Silver 215°:

Temp Tower:

The Benchy bow is intended to highlight cooling issues. Be sure you part cooling fan is aligned to blow cooling air on the print properly. Possibly reduce temps a bit, at least to test the bow. Some filaments just won't print good overhangs. Silk filaments can be tricky.

The Galaxy Silver one prints just fine.

So i think my cooling should be enough?

I did change the cooling shroud with the delta-p one:

I did not think of testing the old shroud, so i dont actually know of this one is better. I trusted the comments saying that it is good.

I will try installing the default one again and see if it makes a difference.

The Delta-P fan duct is hot garbage.

The default fan shroud fixed it.

Now i only have a small corner on the backside that does not look nice, bit it is only minor.
