Budget no issue - Be Quiet Silent Wings 3, engineered for the best compromise between noise and performance.
Best Fanboy option - Noctua, they make the best fans full stop
Necro I know, but another Phanteks fan has developed the noise problem the OP has. I bought 2 X 120MP and 2 X 140MP (for 2 builds). So for me, it's 1 X120 and 1X140 with the issue
Oddly, I bought them exactly 1 year ago, 1st Feb 2020.
