So i got a Nzxt Grid+ v2 today because i wanted to control my noisy fans and make them quieter. I plugged my 4 fans in, plugged the USB cable to the motherboard and plugged the molex cable into the power supply. I then downloaded the Cam software. I went to the tuning tab and selected my first fan, i selected silent mode. The 'save changes' box was greyed out and i couldn't click it. This is the same for all the other fans. However when i click the 'select all fans' button the 'save changes' button is green but when i press it nothing seems to happen, my fans are still the same speed. Any help? (The fans im trying to control are the stock NZXT h440 fans)
