Yes, the utilities are the same and you are quite correct, you don't really need any of them. I never install these unless I am troubleshooting or checking things out.
Having now spent a few hours playing around this morning, I too am beginning to think there is an issue with the Fan Control Options on this motherboard. It isn't a problem for me but, that doesn't make it right. As Far as the System Fan Control goes, there is only the Option to Enable/Disable in BIOS but no actual parameters to adjust. I will install EasyTune6 to see if this offers any options and report back when I have done so.
