I recently purchased a "View 71 RGB" chassis. Everything looks fine, however, the fans does not seems to power on. All the other components work, the RAM, CPU, Graphics card. Just that I don't think the Thermaltake controller is getting power. I have connected the fans and the 4 pin cable as instructed in the manual, but no luck. I've tried multiple Fan controller 4-pins (12W) on the motherboard, still the same issue. Have I got defective controller?
