633 fan 4 stuck on full.


New member
I have a 633 USB, and fan 4 suddenly jumped from off to full speed. I have stopped the 633 service and tried wintest, but no matter where I set the speed, any fan on 4 is full speed.

Does this sound like something that could easily be fixed? If not, is there a way to get one of the other ports to handle more current? Ie. 3x .76a 84cfm vantec fans.
