Something you should know, the decibles aren't everything. If it is high pitched it will drive you nuts!

True, but won't that mainly be caused by air resistance?

sometimes. Other fans just have a damn whine due to rpm.

My case was full of those "stamped" fan grills in its chassis. I have cut out (with small cutters) five of them (2 rear, 2 mobo side, 1 front) and sound levels have dropped considerably (though it is still loud due to the amount of fans I have) I now run three at low power (for hdd cooling) and the remainder at high power...

One of my cases has one of those stamped grills which probably blocks half of the air that is supposed to go through it. One of these days, I should cut that grill out and use one of those wire ones instead. That case is fairly flimsy, though; what would be the best method to go about cutting out the old grill?

I used a small pair of snips - (ones that have broad cutting blades that taper to a point), and just chomped out all the sections between grill at its outermost edge, then sanded and placed a chrome fan grill over the hole.

(An edit to my last post: all low voltage fans are now running at full steam again so noise is back up a bit once more)

If anyone's still wondering, 1dB is barely noticed; 10dB equals 10 times the sound pressure but sounds twice as loud; doubling sound sources makes about a 3dB difference.
