I have a simmilar Problem, 2 Noctua NF-F12 iPPC-3000 PWM Fans with a y-splitter already killed 3 of my Fan headers. I thought the first one was just a bad one, the second one died shortly after that and the third died within a day, the fans are rated at 0.3A, so it shouldn't be a Problem, my other Fans on it are 3 NF-A14 PWMs, which are rated at 0.14, so no problem there. I really like the commander pro, and my mobo doesn't support Speedfan.
