The 3 Amps might be a problem the controller on the S5 cant turn it the rest will be fine if the controller turns it , i know with one of the delta fans you need external power to power it. if you want to use it with the  S5 I think  it's at 3 amps id have to go look at that fan. just looked at the fan  its at 3.9 amps so I'm not sure with your fan if it will or won't . IF you just want to add a second fan to the stock fan that's even more noise + you won't need but one fan if you stick with the stock fan .
