My Phanteks P500A case fans exhibit odd fan behaviour.

I have a Super Flower Leadex III 850w on the way to replace my seven-year-old Corsair HX750. But I'm unsure if that will change anything.
I RMAed the fans twice and ruled out the case fans being an issue.


A few questions:

  1. Will replacing the PSU fix the issue and make the fans spin more consistently?
  2. Is the Super Flower PSU quiet? I'm looking to budget some of my money to make the PC even more silent.

Cheers!
