Thank you for all you for all your help, unfortunately, there would be no way to return them, but I think I got them working ok now. Just needed to give it a bit more voltage to get it order the start stop function. But If I do need to get new fans, ill look into those Corsairs

hmm ok, is there any way to overcome the Start-Stop function of the EK-Vardar EVO 120ER Black (2200rpm) https://www.ekwb.com/shop/ek-vardar-evo-120er-black ? As I have 32 of them that I need to control with the Aquaro and a bunch of Splitty9's.

I just received my Aquaero 6 Pro and I updated the firmware. Have connected USB and power to the Aquaero.The red LED next to Aquabus Hight keeps blinking. I am using a Splitty9 and all the fans are performing ver erradicly, none of them are staying a consistent speed. They are the EK Vardar 2200 RPM PWM Fans. Any help would be appreciated.
