Each of those fans seem as if they can be plugged directly into a power supply and work fully because they have molex connectors. I don't know if they are just adapters that still require you to have 3/4 Pin connectors on your motherboard.

Can any/all those fans be plugged directly into a Power Supply and work with no attachment to the motherboard? My MB only has 1 4 Pin connector for Case Fans.

yea im pretty sure u can plug them directly into the power supply but if you do so, you don't get to control fan speed, i do it because i just want them to spin as fast as possible lol

If you can plug one or two of them into your motherboard you will be able to control the speed.

If you use the adapters and plug them in to molex they will run at full speed.

If you want to be able to adjust the speed and have lots of case fan you might want to look at getting a fan controller.
