Maximum PC

Hi
This is my first time on this forum and my first PC build. I have an ASUS P8Z77-V LX LGA 1155 Intel Z77 Motherboard. My case is a Corsair Obsidian 550D mid-tower. This case came with 3 120mm fans, 2 in the front and 1 in the rear.

The fan headers on the Motherboard are labeled CPU Fan (4pin) - Chassis fan 1 (4pin) - Chassis fan 2 (4pin) - Power fan (3pin). I know where the CPU fan get connected to so my question is: What are considered the Chassis fans and what is the Power fan on my case?

Thank you
Andrew

All the fans of your chassis (case) are Chassis fans. Where you plug what fan into is of your own knowledge. You have 3 fans...plug 'em in as you see fit.

I have several versions of the P8Z77-V board, but not the LX. You shouldn't have a "PWR" header these days. That is meant for PSU's that needed/had externally regulated fans so we can control them from the MOBO settings in the BIOS. I haven't seen that in a very long time. But you can still connect a case fan to it if you have one and still control it from the BIOS. Just know it's not your PSU and is so-and-so fan you hooked it to.

Quickly, they're just labels and act no differently. When you hook a fan to one of them, you'll know what fan it is to tweak in the BIOS. The CPU, yeah it'll be different and speaks for itself.

Thank you Chumly for your help. I basically already hooked the fans up like you said just using common sense and everything worked out perfect. The fan wires of 2 of the 3 fans that came with the with the chassis just barely made it to the headers on my motherboard. I put fan wire extensions on them just to have some slack on those wires.

I already have 3 Dell PC's but I had to build a PC just to see if I could do it. I have to admit it was a small challenge but a lot of fun and I'll do it again when I have to.

Thanks again for your help
