thanks for the detailed explanation, I run DXP4800 PRO (which uses the same Super IO ITE8613E) and saw this comment which upset me initially. But I then decided to try the ITE IT87 DRIVER and FanCtrl Plus, turns out, both work great in my setup. Not only I can see the new dashboard panel with the fan speed and reason for it, FanCtrl actually does control the fan. I first tried the "fan discovery" which was able to max-spin both the CPU fan and Rear fan (Noctua in my case) and then I tried changing the Fan speed percentage to see if those would make a change and they did.
