Unbelievably loud These are totally unusable for any sound level sensitive applications. I measured the decibel level directly in front of this unit at 86dB, which falls somewhere between a vacuum cleaner and a truck engine! Even working near this thing in a server room would be brutal and probably require earplugs. Buyer beware. I give it two stars only because I'm sure it works fine, but not for my or any other situation that requires quiet operation. August 29, 2012
