A:AnswerHi,
The ELITE CAPELLIX fans are designed to be used with the cooler's included Commander CORE controller for optimal cooling. Connecting the iCUE 4000X RGB's fans to the Commander CORE is optional as you can still run the 4000X's Lighting Node CORE separately as long as you have the spare USB 2.0 header/SATA power connection. If you have any additional questions, please feel free to let us know: support.corsair.com

A:AnswerThree. You can buy fan header splitter cables to run two fans off of each header for a total of 6 fans on 3 headers. Each fan draws 0.3A. Your motherboard can likely can support at least two each but check first.

A:AnswerThis is just the box for a pc and if you want to put the parts from a hp desktop then you are most likely out of luck because they have custom parts that will not fit. This pc is only for PC builders that have the proper parts.
