what happens if i connect the fans to the directly to motherboard, will they run at max all the time, what i want is for them to automatically increase in speed as the cpu gets hotter and not the other temps just like the stock h80 fans
it draws power from the molex (meaning it'll run 100% all the time) and output the RPM info on the yellow wire you can plug into the mobo for RPM monitoring....
no known mobo header (except for maybe specially built server boards) can handle a delta (especially a 30 watt delta)
to achieve what YOU want it to do, you'd need a rheosmart controller and plug the fans into the controller and the rheosmart controller will take the PWM signal from your mobo and control the fans accordingly.
my personal recommendation is to go to youtube and look up some 240 CFM 120mm fan vid and listen to just how LOUD those fans will be.
