or something like it? My friend wants to have an extremely quiet computer and was thinking about replacing his four case fans with the Papst 12dB fans. I have no idea what the CFM is for those fans, but he wanted to know if anyone has done this before and what the results were. He owns a Lian-Li PC-65 case. If anyone has done this, or something close to it, let me know what you think. Thanks.
