If you're getting those temps then I think it's your case and airflow that are the issue. not necessarily the fans.
I use ML120s, ML140s, and Silent Wings 3 120's in a totally silent build at idle and quiet at load. I never run my ML's higher than about 50%, granted only a 9600K at 4.8ghz but I'm idling at 29C in the Summer doing office work and browsing internet. Silent Wings 3 are quieter but honestly not by much, ML120 go ultra high RPM compared to most fans so they are very noisy at that level but I never ever need the 2500RPM they max at, I never run over 1000RPM at max or so.
I wouldn't put with 50c idle at all. I think there's something's wrong with your case and airflow, you could get much better temps and noise with just air cooling with a good mesh front case.
