3 pin fan splitter?

[Guitarman0]

I want to run 2 3 pin fans for my CPU heatsink at the same RPM but with the RPM of the fans being upped as the temperature rises. I currently have this working with one fan but I am forced to run the other on another header which runs at a different RPM so the 2 fans are running at different speeds. The RPM from the CPU header is being controlled via voltage (set in the bios) and I am wondering if THIS would run the 2 fans at the same speed while also giving my mobo the RPM information of 1 of the fans (the 2 fans are the same) so my mobo can adjust the rpm accordingly?

I hope this makes sense
Thanks

That should do exactly what you want, it'll read the speed of one of the fans but send both the same voltage. Then simply set the fan to pwm/silent (whatever setting it is in the bios) and the mobo will speed up the fans as temps increase.
