I have ordered fans that allow me to use a molex instead of the motherboard for powering the fan.
Does it matter which one is used?
Plugging a fan to motherboard vs a molex connection

If the fans need much power (say, over 3W/0.25A) You can burn out the motherboard connector.
If You use S1 power save mode (stand-by), usually fans attached to the motherboard will stop, but fans connected to a molex connector will continue to run, as the PSU is still on.
RPM monitoring requires a connection to the motherboard's header. The power can still come from the molex, just the sense wire needs to be attached.
