Double-check:
* on the fan, red wire is positive.
* on the power brick, white-striped wire is positive.
Yeah?

Either of those power supplies will work. The maximum current your fan
will draw is 0.24 amps or 240 milliamps. The current numbers listed for
the power supplies you show are the maximum amount they will put out and
they are definitely not under-powered for what you are trying to do.
