specs are here... looks like it's fairly quiet and a good amount of cfm...
Tho.. Kinda wondering about replacements. Would be interesting to see the cost of a new fan. Nice design tho. I think it's over kill and who knows if the case is decent. After being spoiled with a full tower quality aluminum I don't think I could ever go back to a crap case again. Tho, if the fan is the only thing your interested in then by all means! Good Deal!
