Rosewill CHALLENGER Black Gaming ATX Mid Tower

This is a first time build and so I am a little unsure as to what I need to connect the three case fans. Will I daisy chain them to the one chasis fan input of the motherboard, or do I connect one fan to the motherboard and the other two to the PSU? I am not sure what pin configurations and cable type I need for these fan connections. I just want to make sure I have everything I will need when I submit my order. I am sure this is not complicated and though I tried to look up all of the specs for these parts I am still a little confused.
 
Hello JR2112;

According to the NewEgg customer comments on that Rosewill CHALLENGER case the front and top fans have just the molex 4 pin power connectors directly off your PSU. I guess that means the rear case fan can use a motherboard fan header.

Normally you only connect one fan to each fan connection on the motherboard. Each fan connection on the motherboard should be identified in the owner's manual that comes with the motherboard. There may even be a diagram in the manual.

Make sure you connect the cpu heatsink fan to the cpu fan connection on the motherboard. That is a mandatory requirement for pc operation.

Normally the cpu heatsink fan and the case fans are pre-wired. I took a look at the photos of the case you selected. I could clearly see the 120mm fan on the rear panel was pre-wired and had a standard fan cable connector. You should not need any cables or connectors. It should be a simple plug and play.

WR2 - Thanks for catching that! I didn't see it in the photos.
