So I have an ASRock Z77 Pro4 (http://www.asrock.com/mb/Intel/Z77%20Pro4/) motherboard and I'm trying to hook up my fans. I have the CPU in CPU_FAN1. Here are my remain slots:
CPU_FAN2 - 3-pin Empty.
CHA_FAN1 - 4-pin connector, all of my fans are 3-pin.
CHA_FAN2 - 3-pin connector. I have a splitter so I can at least plug two of my four fans into here.
PWR_FAN1 - 3-pin Empty.
Here are my questions:
1. I'm trying to let the motherboard control the fan speed automatically, not with PWM as I don't have PWM fans, but just with the standard motherboard auto controls using 3-pins which according to my research will work. I understand that CHA_FAN will have this functionality, but even though they're case fans and not CPU fans, can PWR_FAN and CPU_FAN have automatically controlled speeds by the motherboard and work correctly?
2. If I need to use the 4-pin CHA_FAN1 can I plug a 3-pin into it without any negative impact?
3. I accidentally bought a PWM splitter that I could presumably use if #2 is OK?
Any other advice? I want to get my PC up and running tonight and want the fans controlled, but I need to find a slot for my last two fans somewhere between CHA_FAN2, PWR_FAN1, and CPU_FAN2. I don't have another adapter and they don't appear to be sold locally so I'd prefer to work with what I've got. Thank you!
