- Smart mode seems to be problematic. I don't think the fan hub changes fan rpm as fast as Fan Xpert needs the changes for "Smart Mode" to function properly.
- Have you tried changing the curve temp/speed low or high setting a little to see if that will stop the fan changing speed? That is what I had to do on my system. Seems the temp was increasing slightly causing fan to speed up slightly causing temp to drop slightly, causing fan to slow down, causing heat to rise, causing fan to speed up, etc.

I have the PWM cable from the fan hub plugged into my CPU_FAN header. The only true PWM header on my motherboard, just as the manual specifies. When I plug the sata power in, all fans ramp up speed to near 100. Right now, I just have the 4pin fan hub cable plugged into the motherboard and I get range from 30-100%.
It only monitors the speed of the fan in position #1 on the fan hub.
I am not using smart mode, I use RPM mode. I said that I tried smart mode to see if that fixed the problem, it does not. I use RPM mode and the fan speed bounced up and down from my set speed.
None of that applied because I don't use smart mode.
