You can put the two 2Pac miners in the 2.4A USB Hub ports (there are four total data ports) and you can plug the fan into one of the other non-data ports.
It's not cheap, but then his current ports that also pass data are kind of odd and are scarce.
Only .5A a port is pretty bad, to my experience I have run these miners just fine on 3.0 hubs. They cost a little more than 2.0 hubs but they're necessary for real OCing. As for the brand, ORICO is a decently good manufacturer of hubs. Never had issues with them, just always make sure to check amps per port.
