I just finished my new build in an Nzxt tempest and all the case fans have male and female 4-pin molex and a 3-pin connector. Is it ok to connect the case fans to the power supply and the motherboard both or should i just let them be powered off the 3-pin on the motherboard so it can control the speed of them, or should i just hook up the molex and let them run 100%(not counting the cpu fan which is hooked up to the motherboard).

I dont mind the noise really and i am planing on getting a fan controller at some point, but you did not answer my question, if i have the fans plugged into the motherboard do they not need the molex connection plugged in or should i just plug in the molex and leave them off the motherboard?
 
You only plug the fans into one source, either the MB or directly into the PSU.

You probably want them all at 100%. Having a fan or two connected to the MB while the rest are not would not make much sense, and I doubt your MB has headers for all your fans.
