If the fan was pulling extra juice and also plugged into Port 1 or Port D it might have messed up the power going to the hub chip. Any other ports should be pretty much bulletproof.
If you plug the hub in and run 'lsusb' it should read out a Terminus FE2.1 7-port USB hub on the bus.
It does now which is weird. It didn't when the fan was in port 1.
