Did you use the gx12 and meanwell power supply...?I'm not sure what has happened your case, but something blew in my GTX 970 mini a month ago or so. The fan ran at what I guess would be close to 100%. Could not control RPM at all. I pulled off the shroud and stuck a 92mm Noctua fan on it and it was way more quiet. I still can't control the RPM (this model doesn't have PWM), but it still keeps it pretty cool for gaming and everyday use. I'm in the same boat where I'm just waiting for the 11 line to come out.
