Since noodles don't take that long they are normally not cooked in a pressure cooker. Even those recipes that use a pressure cooker puts the noodles in at the end and keeps the cooker uncovered.
It would be quickest just to bring your water to a boil in a pot, salt your water, add your noodles, and cook al dente.
I hope this helps.
