Hello Everyone, 
Amazing Octo, Leakshield and High FLow impressed me every times, controlling fans at ease. I will share the snap of PC soon. 
 
After a few weeks, One fan 4 acts in surprising way as RPM is going to increase at 10% and decrease at 90% :/. 
I tried to reset the controller, but it is still the same. Please have a look at 2 images. Is there any way to fix the solution? 
Please help!
