Thank you!
1) solved indeed I forgot I mixed 2 different types of fans. So now fixed.
2) ok currently i have hooked 3 front fans and 3 radiator fans to it which I want to change independently. So to do so I need to only use 1-3 for radiator and replug the 3 front fans?
one other unrelated question, for my GPU I had to take another brand as Corsair was not supporting my GPU. Is there a way I can connect my AlphaCool block to the commander pro?
