Was playing Battlefield 4, eventually restarted my computer, and up come the black screen with a message that read "CPU Fan Error. Press F1 to go to SETUP." I went into the BIOS and CHASSIS FAN 1 is N/A while 2, 3, and 4 are displaying their RPM. It reads the following:
CPU Fan Speed: N/A
CPU Opt Fan Speed: N/A
CHASSIS FAN 1 Speed: N/A
CHASSIS FAN 2 Speed: #### rpm
CHASSIS FAN 3 Speed: #### rpm
CHASSIS FAN 4 Speed: #### rpm
I'm not really sure what just happened or how to fix this, but all the fans appear to be working just fine and everything is cleanly connected, but somehow this message won't get out of my way. I have been trying to see what kind of fans I have and all I've come up with is that they are Corsair ones. I can provide pictures if needed.
Any ideas what I need to do to fix this? I'm a PC noob so 1st grade english is a must.

You can disable the warning somewhere in the BIOS (at least it's like that on all boards I've seen).
But make sure that fan is really running! I mean, actually look at that fan and see it moving. It's the one on the CPU cooler. That one is important. The message was not about any of the case fan connectors.

You mean the large fan on the side? That one is running just fine, as with all the smaller ones. Where can I disable the warning?

Large fan on the side? If you have a Corsair Hydro than maybe your pump failed?

I don't know what that means. As stated in the OP, plain english is a must for me when it comes to computer rigs because I am clueless about them for the most part. All I know is that all fans are working just fine (they appear to be), all cords are connected properly, but when restarting or hard-restarting, it gives me the CPU Fan Error message again.
I tried disabling the Show 'F1' key when error part. It loaded up properly and now i'm back to the desktop but the fact the error screen even came up means something could potentially be wrong.
EDIT: It still displays a CPU Fan Error screen, but after a few seconds it closes it and loads up to the desktop.

In the first post, you mentioned the error message you see is saying something about "CPU fan". Then you mention you can see something about several chassis fans and the first one shows no RPM.
As far as the software is concerned, it names a fan after the header/connection on the board. It does not know anything about how the fans are arranged in reality. On your board, you will have one or two CPU fan headers, and you will have two or three or four system fan headers.
So if you see somewhere, chassis fan number one is not running, the software talks about what is connected to a fan header named SYS_FAN1 or similar.
If you see that CPU fan warning, the software means the header that is named CPU_FAN or something similar.
You can see the names of the fan headers in the manual of your board.
Disabling the warning might be somewhere on the screen where you can see temperatures and set fan speeds. But do check all your fans! If the CPU fan is not running, that one has to be replaced. If you see it running, the error message might just be a mistake of the software.

When I first got the message I opened it up and the large fan on te side was somehow disconnected. Even after reconnecting it the error message still comes up despite all fans spinning. It probably is a software bug

This is out of your manual: http://i.imgur.com/3pg1gbm.png
You should check whatever is connected to the thingy where I scribbled "CPU" at the top. That's what the error message you mention refers to.

Very helpful, thank you for that. However, upon looking at it, there's actually nothing connected to the CPU_Fan socket, or the Opt one. So confusing :S

You're supposed to connect CPU fan to that slot, i spent 15 mins messing around once because my motherboard refused to reach bios without something plugged into it. The fan on the CPU heatsink is 10x more important than any others so make sure it's spinning. If it's on that slot, it'll be detected as cpu_fan

That would mean that you should plug one of the cooling(correlated to CPU temps)fans into that socket. The software isn't happy because you don't have a feedback controlled fan attached for it to adjust based on the CPU temperature. Doesn't necessarily have to be a 4pin, but that'd be better.

OK dumb question, which fan is the CPU fan...........................

The one that goes on the heatsink (block of metal) that sits ontop of the CPU.

Ok done. It's a small corsair box in the middle top. I put it from fan3 to CPU_fan and everything is working now. I'm not sure why it was on fan3 to begin with, or why it never gave me the error message for the whole previous year I've had this thing. That was how I originally received it and I had no issues with it whatsoever.

Is it something like this: http://content.hwigroup.net/images/products/xl/118110/corsair_hydro_series_h60.jpg ?
If yes, and there are two connectors, one for the block on top of the CPU itself and a second one for the fan on that box you mentioned, you will want to put both of those in the two CPU fan headers that your board has next to each other.

Yes that's exactly what it looks like. The small corsair box has one connector, which I put from fan3 to CPU_Fan. The fan itself (larger black box) might have 2 connectors actually, I can't tell because the cords hidden back there, but they're both in fan2 and fan4. Opt_Fan socket is empty.
EDIT: I looked again and there's actually 2 fans on the larger piece, not just one.
I took some pictures to show you my setup.
As you can see, there are 2 fans attached to the top of the CPU.

Zooming out, this is what it currently looks like:

Both fans on the black box (top left) are plugged into fan2 and 4, which I circled. OPT_Fan at the top is empty.

You don't need it to be plugged in. The only mandatory(highly recommended) fan port in the majority of systems is the CPU fan header.
IIRC, unless the other fan ports have controllers built in, most board treat them all simply as outputs and sends 5V to each. The reason the CPU_fan header is important is that it allows the board to respond to an increase in CPU heat by increasing the heat dissipation capacity of the heatsink, usually by increasing the correlated fan's speed.

So basically I'm good to go then.
