I am new to building a pc, making my second one now I have a question on a fan controler.

Ok making my second PC. First PC I didn't use fan controller this time I am. So my question is. Do I connect fans to molex connector then also to the 3pins to Fan controller, or do I not connect molex connector to the fans and only connect the 3 pin to the fan controller?
tyvm for help.

When it comes to the fan controller, only connect the 3-pin wire to the fan controller. Do not connect the molex connector on fans to the PSU. Also, fan controller itself has molex/SATA power connector from where fans get the needed power.

In other words:
Fan 3-pin wire - connect it
Fan molex wire - do not connect it
Fan controller molex/SATA - connect it
