RGB VS Addressable RGB Question

[Jas99]

Hey, 

I understand that's plug a 5 v rgb strip into a 12v connector will fry the strip but what about the reverse? If I plug a 12 v fan into a 5 volt connector? Then what?

It won't hurt it. You can always try and see what happens. It will probably just spin slowly.

Assuming the fan has low enough resistance: It'll spin extremely slowly assuming the 5v is actually outputting the full 5v at the moment. Otherwise, it'll just sit there getting hot from electrical resistance

I have it plugged into the correct power header but I'm talking about the rgb connector

Depending on which way the fan was plugged into the header either

A) The fan would spin extremely slowly backwards and put a marginal voltage to your Data line on the RGB header
B) Not spin but hot from too much resistance and put a marginal voltage to your Data line on the RGB header
C) Nothing at all since pin 3 reports fan speed and pin 4 controls fan speed
