i got an old 120mm 120vac rotron whisper fan from a BIG server. the thing i love about this fan is it pushes 70 to 80 cfm with just 34-37 decebles. I was wondering how to get power to it and than it dawned on me. my PSU has a moniter power output and i have a seperate cable for my moniter so it sat useless. i just put the ends of the wire into the holes and i instantly have power and the best thing is it works on the main switch so when i turn my comp off it goes off too. NO SEPERATE SWITCHES OR RELAYS!!!! i hope this helps someone.
