I was thinking of ONE psu, that can also be fitted into a case, not 3 or 4 in series. Your example is not fine-adjustable to get the best performance for your pelt setup, either. And it's not exactly user-friendly
I'm aware that people in this forum are the most pro guys in pelt cooling, I was expecting the most resistance here because you people know how to help yourselves, and that's great. I thought I would post the link here anyway. It's fun
