What current did you set them to? Nema 17 is the face plate size the length can vary a lot. Your steppers should have a current rating as well. You can do it by trial and error but things are much easier and safer if you find a data sheet.

If you can’t find the proper info start by turning the current down until they are pretty much silent while idle.
