My case, a ThermalTake Soprano ATX (piano black), has three case fans included. My motherboard, an MSI P965, has a total of three fan connectors on it - one for the CPU fan, one called ''SYS_FAN1", and another called "NB_FAN1". The manual offers no explanation as to what the difference is between these two. Now the case fans all have three plugs on the end. Two power plugs (4-pin, male and female) and one small 3-pin plug. It would fit in the fan connectors on the motherboard. My question is, how do I go about connecting all three? Do I use both the motherboard and PSU connectors on two fans, and just the PSU on the other?
I'd be grateful if you can offer any input on what these motherboard plugs may be for and how I should go about connecting the three fans. I'll post a picture below.
This picture shows, from top to bottom, NB_FAN1, the motherboard connector on one of the fans, SYS_FAN1 (to the right), and one of the PSU connectors on a fan cable (larger and closest to the mottom).
Thank you very much in advance!
I just had a thought. Would it be correct to plug in one of the fans to the motherboard (SYS_FAN1) via the small plug, plug that into the power supply, and then chain the other two fans from the female plug on the fan? That makes a lot of sense to me, because it seems a fan must be connected to the motherboard so that it can be controlled - and if they're all connected to the first one in circuit, would the motherboard not then be able to control all three?
