if i have limited 3pin for cpu fan connector on mobo how to connect the rest of the fan?
1) use a FAN hub
2) use a molex splitter + PWM fan connector
3) use a Y splitter to your mobo fan headers. 2 x fans should be relatively safe. I've seen people use 3 before. Just make sure total ampere does not exceeed 1A.
4) molex to molex passive power output connectors ---- be mindful this will cause your fans to run full speed.
that's about it really....
