4 pin PWM fans...

OK so just built a custom loop for Titan sli cards, nothing else in the loop. I have a 360 rad with 3 fans all with 4pin PWM connectors, and also the EK pump/res combo has a 4pin PWM fan connector. My motherboard only has 3 x 4pin sys fan connectors available. But it does also have a second CPUfan header on there currently unused. I could stick all 3 of the 360 fans into the sysfan headers, but am I right in thinking that if I plug in the pumps PWM fan into the cpu header it'll be the temperature of the cpu that dictates of the speed of the pump? Or does the pump just have a constant speed to it?

MSI x99A Mpower. Splitters sound like a good idea, best to have the rad fans running all at same speed. I really thought the cpu fan was connected to monitor the socket temperature!

Cheers Frank, seems like I've read some bum info on the interwebz then Just bought some splitters as that looks like the best solution for my case. Thanks for the help, happy new year!
