It all started when I was using my pc as normal, My pc froze up on me and I wasn't able to do anything. I resorted to shutting down my pc via the power button. When I turned my pc back on, none of my 10 fans were recognized. I made sure everything was plugged in tightly, and still nothing... I had another fan controller laying around, so I hooked it up and it worked perfectly with no problems at all. So now I'm wondering, is it possible that the fan controllers have gotten damaged or corrupted in some way? And if so, is it possible for me to fix it? The controllers do not seem to be available for individual purchase, so it would go a long way if I was able to get any help at all with this.
