Hi!
I own a Gigabyte B450M DS3H motherboard and a case with x4 fans (with 3pin and molex connectors). My question is, can I plug all the fans throught Molex in each other, then take one 3pin connector, put it in MB and have control on all the fans?

No, that config could very well end up back feeding and damaging the motherboard. With fans that have 2 power options you only use 1 or the other not both.

If you want to control multiple fans from 1 header you need a fan controller.
