Question about fan splitters and case fan connectors?

Nope, the PSU still supplies it with a 12v connection, the motherboard connection just makes the fanspeed adjustable.

So i have a fan splitter that connects two of my fan cases in my s340 case and is also connected to my power supply and motherboard. A weird thing I realize while cleaning my pc was that the fans would still work even when the fan splitter no longer connects to the motherboard after i have removed it for cleaning up my pc. Shouldn't they stop working after they have been plugged out of the motherboard?

Don't call me a nerd, it makes me look slightly smarter than you

since the splitter is also connected to your PSU i think what happens is they just lose their PWM signal and keep running at the speed they where running at since they are getting their power from the PSU.
