This is a very good budget case which support many fan placements, unfortunately, the front panel has a design flaw that keep irritating me. Noise. I'm using the default 120mm front intake fan which produce louder noise when front panel is installed. Inside the front panel, there are small grills on the side of the inner part where the air sucked in inside. Picture link

These grills are the problem, either they are too narrow or badly designed,, air went inside produce noise. I detach the front panel for testing sake and it is true, the noise is significantly reduced. The problem is confirmed located on these grills. I tried swapping the fan on the upper slot, still the same.

Anyone has ideas for modding the grills ? Cutting it would be permanent so I think I should ask first. Or is there any other solution related to modding this case to achieve quieter noise ? I need both fans on front intake to cool a lot of HDD in my nas box (most of it are 4TB drives, which are very thick in height, so slower fans/quiet fans are not an option as the machine will run 24/7).

Thanks

@corroded, @terry4536 : by default, my fans are actually quiet at expected level, it is only, when the front panel is detached. The temperature level of the HDDs are also at the safe zone using the current RPM. Slowing it down might increase the temperature so I will consider it as last alternative
 
ok... then do like terry suggests... get quieter fans. I had to on one of my cases... the stock 140mm was a helicopter in the room... I replaced it and... tada barely a whisper.

also look at the drive placements in the carriages if you are worried about heat on the HD's, keep an empty slot between them to improve air flow.

Thanks :), I look at a local store and fortunately they sells it here as well. I also found someone have the same problem as mine and attempt to mod the case here. Could use better color combination (damn it noctua, why brown) but, oh well, its a nas box after all, make ups are not important.

@corroded
Thanks, I might look for more reviews for those fans. Correct me if I'm wrong, is the stock fan of 210 is the NZXT silent series ? Because, if it is, then any other fans with the 15-20db will not make any difference unless I do something about the grills.
