LED Fan Wire Fried and Melted

LED Fan Wire Fried and Melted
Just when you think you know what you are doing, you are quickly reminded how easy it is to mess it all up.

First off, I really liked this site with all the helpful and useful information and how reliable it is on buying quality parts. Thanks. So I decided to use the Mainstream Gaming PC article to build my very first desktop computer. I went to Micro Center and got everything I need and spent 5 hours putting it all together. The moment of truth came as I pressed the power button and watched my hard work come to life. Everything worked perfectly. I have been using it for about a little over a month and no problems.

Then I remembered about the LED fan light, something I just should have forgotten about and learned to live without it. I was so excited and proud that my PC came on and nothing bad happened that I forgot to check out the awesome red LED lights glow in my desktop case. I chose the Cooler Master HAF 922 for my case. I couldn't quite figure out how to get the LED light to turn on so I went online for an answer as I am doing right now. I found a forum and the same question and they said look for a red and black wire in the back of the case. I found the wire on mine and noticed it was way too small to reach the motherboard or power supply so I figured there must be an extension or something in the box that came with it tied up inside the case. I took it out, found 3 extensions, I took one of them and connected it to the other. This wire has a red black and yellow wire with 4 pins sticking out the end in a sort of clear plastic casing surrounding the pins. There was another one on the same wire too. Hopefully, someone will know what I am talking about. I noticed that there is still something missing. I then looked in the power supply pouch to find a cord that looked like it would fit that had the same colored wires. I connected it and plugged it into the power supply. I turned on the PC and it booted up normally like always. Then I pushed the LED Fan light button and watched happily as the red lights came on and then in horror as a bunch of smoke came out of the desktop shortly after. I immediately unplugged everything and switched the power supply off and took a few minutes to open my back door to and grab a towel and blow the smoke out. After that was over, I found the LED Fan (black and red) wire was fried and the plastic over the wire had melted. I am alright. I did not get hurt. A little bit shaky though and there was no fire.

I consider myself an electronics expert. I take precautions and usually am very careful when I am handling something expensive or fragile. I am able to fix certain problems my family can't when they ask for my help. I am saying this so you know that I wasn't careless when I did this if I unknowingly did something wrong without realizing it. So can someone please tell me, what happened and what possibly went wrong? Nothing else seems to be damaged in any way.
It is extremely appreciated of any help you can give me. Thank you very much.

I turned on my computer and everything seems to be working. My friend told me that I did plug in everything correctly but I may had too much current running through the wire and that I need to strengthen the wire to allow for the change. I don't know how to do that and I am in no hurry to find out, plus I need an entire new wire to connect it. From now on, I am just going to live without the LED. Nothing is fried or appears to be damaged. The only thing that seems to not be working is the port I use to connect my keyboard. I can get into the Windows start screen but I kind of need my keyboard to put in my password. I can't check out anything else until that is done. So I am off to the store to buy another keyboard that has a USB instead of the other one. That is all for now. Thanks for reading!
