Quick question for Mr. Teal.

I noticed the board has several 4 pin fan clusters.  How much power is available at each of these for fans.  I have a few 3.3A 12V server fans.  Can I power these off the board or should I just use  dedicated power from the supply?  Also how much power is available for the pins labeled pump, since I'm thinking of cutting my H100i SATA power cable and making it fit a 4 pin fan connector.

thanks
