lol wow. thats stupid bobo, you can get a REALLY good fan controller for $20 on newegg... like 4 channels (i only use two for all 6 fans) personally, i decrease fan speed to minimum normally... doesnt even effect load temps ive tested.
there might be a setting in your bios under like pc health or something like that. try looking for it. mine calls it "full-on" versus "smart-fan"
thats it if you want it, definitely worth the money to me http://www.newegg.com/Product/Product.asp?Item=N82E16813999505
i keep my fans 25% extra than the lowest while im playing music and such, and all the way down (doesnt turn them off) while im sleeping.
i keep my northbridge fan plugged into the motherboard on the setting "full-on"
