Grilles can really increase the decibel level alright. Had a 200mm at the front of that Corsair 600T. Lots of owners cut out the mesh grille but I didn't want to do that. Instead I mounted the fan on stand off bolts putting 1cm between the fan and the grille. Ran a strip of plastic around the 1cm gap. Turbulence and noise problem solved without hacking the case.
Free space on both sides of fans makes a huge difference in noise .. be it the fan interacting with grill, HDD cage. filter, and etc. Generally speaking the less restrictive the grill and / or filter is, the quieter the airflow and fan will be. Silverstone and Puget Systems both have done good articles about grill noise and airflow.. Both are in my "Ways to Better Cooling" thread.
