Why not? There is absolutely no reason why a cpu must be under max cool constantly. It's more wear on the fan, motherboard and ears. No reason why software cannot be used to lower fan speeds and still keep respectable limits. Most of the time the cpu is barely running over idle anyways, only under heavy usage does it really need max cooling. Even running bios presets is still software. It's why ppl attach fans to the mobo in the first place. If you are not going to use any software, may as well hook through fans directly to the psu via sata/molex and have done.
