can i use Sunbeam 20W Rheosmart PCI Slot Smart Fan Controller to connect 3 SP120 High Performance Edition fans from my rad to the cpu fan header on the mobo (ASUS MAXIMUS VI FORMULA LGA 1150 Intel Z87 ) so they can be ran by the mobo

so the Sunbeam 20W Rheosmart PCI Slot Smart Fan Controller can handle 20 watts so does that mean i can plug in 20 watts worth of fans on it even though it is getting pluged into the mobo cpu header i was planning on just using the rheosmart pcb with the fans and taking everything else off and running in pwm all the time and hiding the pcb somewhere

That means the fan controller can handle 20W, but the power is still limited by the MoBo header, since there is no other power input. If the fan header can only supply 1A (12W), the maximum power is 12W then. Every board should make this, I'm not sure if the high end boards can do more, but with 1A you're on the safe side. If you're eager to do a bit handicraft work, you can connect a...

One fan needs 0,18A, so three of them need 0,54A or 6,48W. I've read somewhere the high-end mainboards can deliver up to 2A and the fan controller has a maximum at 20W, so that'll be good.
But you have to use one Y-cable, since the fan controller has only two fan headers.

if i use one for every header on the mobo and have them all on pwm will they all ramp up and down togeather

i was also looking at Sunbeam 30W Rheosmart 6 Channel Smart Fan Controller but on here http://www.overclockersclub.com/reviews/sunbeamtech_rheosmart_6/5.htm (using the automatic Smart Cooling System with the supplied PWM cable connected does not vary any of the fans' speed based on temperature. Instead, automatic mode runs the selected fan(s) at the maximum 12v power.) the way i read this is u can only have 1 channel run on pwm in auto and the rest run full speed

sorry for all the ? im building my first computer and also first water cooled computer

If you're eager to do a bit handicraft work, you can connect a 12V cable in parallel from another fan header, then it can supply twice the power. It's limited by the 20W from the controller though.

From other reviews I've read it works with the PWM speed. I don't know which one to believe, sorry. You can read them and look what happens in the most cases:

But they all agree upon one fact, this controller can connect 30W to each header.
