Right, I've aquiredan 120mm NMB 4715kl-04w-b39 fan from work, its out of a compaq proliant server. I've searched the net and all i can find is a weird pdf stating that it pushes 160cfm (true or untrue???). I was planning on mounting it somewhere in my case so i tested it first out of my machine and as soon as i booted the fan took off accross my desk. Me thinks hehe, this should be nice for cooling, however it really isn't the quietest if you know what i mean. is there similar fans on the market that push as much air but are quieter? Sorry i cannot find the dB of this fan anywhere on the net.
