Since it sounds like modifying the existing internals is less than desirable, how about modifying the environment?

Scythe Bay Cooler or the CoolerMaster 4-3 device. I finally bought one. It's a product of solid construction. The 12cm fan it ships with is reasonably quiet, for me, even at +12V. It won't spin up at all at +5V, but probably will at some higher voltages. It has a dust filter in behind the swiss che...

the Cooler Master fans in 6 packs. http://www.newegg.com/Product/Product.asp?Item=N82E16811999084 are quite at 7 volts. Awesome. Exactly what I'm looking for! I'm going to pick up a pack tonight.

I'm not seeking the perfect solution. I'm just looking for a reasonably priced solution to reduce the noise to a more acceptable level.

Yes, that's generally FRAID. If there are only Windows drivers that's usually a good indication that it's FRAID. Or just Google. FRAID is not an official term. Even, if you google for FRAID, you won't get any links pointing to any kind of reference or links to RAID with the first 10 pages. (I stopp...

120mm 5.25 bay cooler enclosure?

Is there a decent bay cooloer solution? My six 5.25" bay beast has, well, five 5.25" bays available at the moment and I'd like to dedicate two or three of them to a 12cm fan in some capacity so I can provide some additional cooling at 5V for my six not drives.

Thanks!

It's more like a humming sound. Also I have the computer on a big wooden table, which is probably helping amplify this noise.
