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).
