I need some help. I am running to 80mm vantec stealth fans for intake, 2 28db blue led fans for outtake, turbolink 420 watt psu, a 36 gig hd, and a asus p4b533 mobo with volcano 7+. the fans are quiet, the volcano 7+ is only spinngin 3100 rpm, hd is barely noticable. Hmmm, whats loud in my case? could it be the mobo. its like a high pitch hummin noise..thanks for any help.
