>> Does the difference in Amps matter or will either of these be OK?
Both are so close as to make no practical difference. It's the CFM that matters most, and of course the volts. Get the higher amps for more flow. Noise hardly matters in a SB controller.
Other considerations: Hole position and diameter. You can pretty much tie wrap a fan to the case if you can't get the right hole pattern.
