Just looking at the 38mm Ultra Kaze fan which I take it is similar to what you are referring to. It draws 0.6amps which is not a substantial amount. I wouldn't have thought that this motherboard would have a problem with that.
I'm not sure if 0.6A is the continuous operating current or the starting current. For example, the advertised operating current of Akasa Apache is 330mA, but when I did a test on the fan (supplied it with 12V and monitored the current) the continuous operating current is only 90mA!
