Is there any official information on the power requirements/limits for the fan headers on the blades? I know fans dont take too much power but it seems like the blades can already take quite a bit of power in just for running them.

Just didnt know if it would be beneficial to run the fans through the blades rather than the same power rail from the PSU. (currently have my 4 blades running the fans from 1 power rail and each blade from its own power rail). just trying to think about expandabiltity.
