I'm a newbie to Norco cases bu wanted a cheap'n'cheerful backup server so been spending the weekend standing one up. It's a 3U 3216 badged as a Logic Case SC-316 that takes standard 2U PSUs and has a fan wall of 3x120mm.
I've replaced the fans with Noctua NF-F12 PWMs which are exceedingly quiet and provide good static pressure; however I've noticed they run at full pelt (~1500rpm) which isn't entirely surprising given that the hot-plug backplan they're running from is just plugged into a 4-pin molex and there's no connection to the motherboard.
However, I notice that, nestled right in the corner behind the molex, is a 6-pin plug (in a 2x3 configuration); I'm guessing that this might be to be some sort of PWM connection for the whole backplane - is anyone else her familiar with this and can anyone give any explanation of what this is and if there are any cables/splitter available to hook this up to the motherboard PWM header(s)?
(Server in the middle of a RAID rebuild at the moment but I'll take a snap of the backplane and header when I can - you can't see the connector from the pics on their website since it's down right at the bottom between the drive cages and the fan wall)
