v-core 4 500 pla prints horrible

I just finished my v-core 4 500 hybrid. I decided to use orca slicer for the v-core (usually a prusaslicer person) and I went with the ratrig generic PLA profile.
The material used was a role of PLA which I still had on hand. (eryone silk silver)
I printed tons of that material on a voron with 205 degrees on the nozzle so the default value in the profile seemed fine to me.
So I sliced a small print and started the printer.
My problems began.

1. CoolingHaving the fan on 100% cooling was not an option. It led to "spaghetti", the filament cooling down right after exiting the nozzle.So I turned the fan down to 60%
2. print qualityThe resulting print is literally one of the worst I have ever produced. Holes (rectraction?), missing parts due to them not sticking, bad overhangs (probably due to insufficient cooling) etc.I really don't even know where to start with this, there is just so much wrong with it.

Hence this post.
What settings do I need to look at?
I used the v-core as a reason to get back into the hobby after a 1 1/2 years break (only ran my tuned in voron from time to time for small prints) so my troubleshooting skills are quite rusty.
Any help is greatly appreciated.
