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

You'll probably be limited more by the connector on a single fan than anything else, but you should try and keep the total for fans/pumps under 4A or so. The fans are fed from the merging of the four 12V rails through some 5A low-drop diodes. You'll likely get some current sharing between the diodes, but due to the way diodes work at high temperatures it's best to assume a worst case that all the current would go through a single one of the diodes. 50W of cooling should be enough for any normal situation.

If you want to hook up six 250cfm screamers in push-pull across a triple radiator, pumped by a 1/3HP 3300GPH sump pump, you should hook that up direct to the power supply. Wink

Also, I want pictures.
