Well, my ECS K7S5A does not say anything about fan control on it yet I can hear my fans changing speeds as my comp gets hotter (I have the enermax 350 watt w/FC) I just plugged that little 3 prong plug that comes of the PSU into my motherboard where the HSF is supposed to plug in and plugged my HSF into one of the main power lines. This has seemed to work, though it does not give me any fan speed readings. sometimes it is annoying as I will be playing RTCW online test and in the middle I keep hearing my fan noise change pitch. Oh well, it is worth it for the extra air flow. Hope that helped
