@Boot_WB:
OMG... :-( You should have asked if you weren't sure dude. :pissed:
The original fan is a 5V fan, hence you can only feed as much as +5V to the same connector. Like with any other electronic device, if you feed too much power than what's originally rated...you know what happens...
It is printed on the fan itself that it's a 5V fan.
