I have a Corsair A70 in the Sig rig below & im wondering this. This morning I turned on my Rig wich has been running Great for Months since I built it. Now the way its installed is this.

Heatsink
2 120mm Fans
a Y splitter on the 4 Pin CPU_fan 1 (The corsair is all 3 pin so I hooked it up they way it should be)
2 inline Resistors or something to slow the fans down to 1600RPM
Then the fans plugged in

Im wondering this Is this way 2 much Power for the single 4 pin CPU_fan1. When I booted up my PC this morning the fans did not Power up but When I restarted they worked fine.

I took out the Inline Resistors or whatever you want to call them that keeps it steady @ 1600RPM & did & manual set in the BIOS. In the BIOS it was always set on 3 pin & Performance

This time its set to 3 PIN / Manual. I did notice a big difference in Air increase after removing the Inline's. It isnt really any louder then before. So is it fine hooked up this way

Y splitter & both fans plugged into the 4 Pin or Should they be seperated One on the CPU_fan 1 & one on the SYS_Fan1

If im understanding this right, the problem might be because the CPU_fan is normally set to change voltage to control the fan speed but with the resisters in there and the cpu at idle it might be too little of draw for it or something? Dont take it like i know what im talking about... but did you try it with the resistors in and the cup_fan set to max speed all the time so the resistor can lower it appropriately?
The cup_fan is capable of providing the same voltage as any of the other sys_fan headers so idk.
 
Yeah I know my post was Confusing.

How I had it hooked up was

Y cable (CPU_fan header)
Inline Resistors Cables (to slow the RPM down to 1600RPM)
then the fans connected to the Resistors

Now looking online its perfectly fine for the fans to be connected to the CPU_Fan Header. Im just now wondering maybe the Inline Resistors to speed the fan down to 1600RPM maybe causing the issue?

Like I said I removed them & it does seem to be giving me better air performance now. CPU is idling at 25C. Im just wondering maybe with them hooked up it was going lower then 1600RPM causing the fans not to spin fast enough to start them?

Im not sure this is the first time i had the problem so I didnt know If i should of been concerned or not.
