Asus dual 1070 fan speed spikes

The fans are most likely dc controlled and don't get enough voltage below 30% to start up properly.

 

If you want a 0 rpm mode I suggest setting the second "point" in the curve to 36c and set the temp hysteresis to 3c.

I got a gtx 1070. i have configured fan curve to start the fans at 35c. After the temperature hits 35c, the fan speed starts at 1%.

But instead of fans spinning at constant speed, they turn off and on continuously(temperature is still above 35c here.)

These drops happen till fan reaches its 30% speed, and after that there is there is no drop in the fan speeds.

 

Any idea why this happens?

Thanks, now the curve looks something like this.
