Should I be doing PID auto-tuning with my fan at 100% (Anet A8)

You should run the fan at what you expect it to be at the majority of the time it is printing. If you tune at 100% fan and never use a fan then it will be too aggressive, if you tune at 0% fan and ...

Why does my part-cooling fan cause stringing?

Prior to a move the print cooling fan causes the filament to cool on the outside while the nozzle is still hot, when it then moves it causes a strings to form that will be cooled instantly. This means ...

Why does my part-cooling fan cause stringing?

The fans are allowing the strings to harden instead of break. Maybe you should use more retraction or wipe before crossing perimeters to reduce material ooze during moves.
