I'll try to make ask question as simple as possble. I've one 12cm 3pin fan plugged into sysfan1(4 pin)slot, and runs around 900rpm and silently. But whenever i plug 2nd fan(exact same 3pin fan) into sysfan2 (3pin) slot, it runs extremely loud(almost louder than everything in the case) and around 1600rpm, and pisses me off !. What can i do to lower the speed of second fan, or reduce that shitty noise ?
i couldn't manage to control it, since i im gonna connect more than one fan, i purchased fan controller so that i can control up to 6 3 or 4 pin fans. I'll be able to connect 2 more to up and one to front
