I tried 190, 210 and 220°C, all with the same result.
The viscosity seems perfectly alright at 190° already, so I doubt printing even hotter than 220°C would make a difference.
I have a very weak fan, probably about half as strong as the original one. I can try printing witout the fan, it's a very simple part without overhangs.
With every other PLA, I never had problems like these - I always print PLA with 100% fan on and I got very strong prints from it (with ProtoParadigm PLA).
But as I need the part asap I had to switch to another PLA by now (UM black, I hope it's worth something...).

Did you try to print it with higher temperatures than standard PLA? What if you switch off the fan completely?
