That seems to be the case here, as the smbus probe for your board shows no sensors IC's attached. I have an asus M8N-SLI Deluxe which has an adt7475 and sensors-detect detects that just fine, so either you don't have an adt7475, or Asus has multiplexed the smbus, hiding the sensors in that way. If you really want to know how the additional headers are hooked up you will need to go and look for hwmon IC's, and yes that means you might need to take the cooler of the motherboard. Are they actually all monitored, maybe some of them will drive a fan but do not monitor it? How many fans does windows allow you to monitor?. Refards, Hans
