Hi all, I just installed two new cooler master blue led 120mm fans into my phantom 410 rig, and when i switched it on, it's all fine. But when I turned the fan controller up then down, the fans completely stopped working momenteraly, I had to switch it to high then down again to get the fans back into working order. Should I be concerned? Fans don't draw massive amounts of power. Do they? So tht shouldn't be my psu?
