Hi I got a Markbass mini CMD 151 combo and I got a noisy cooling fan problem too, I went on Noctua site and found a lots of fan but most of them have 3 or 4 pins connecters, the fan in my amp works with 2 wire 1 red and 1 black do you think that there's a model that would do the job in my amp, going via Markbass is really not a good way to have a problem solve... I know I could replace it, but I don't know witch one to choose. Thank you
