I got my 360 on ebay first of all so why its like this I have no idea. The part on the bottom of my motherboard directly under the white thing you plug the fan into had a wire on the taped to it to some part on the other side. http://img36.imageshack.us/img36/887/pict0148lt.jpg http://img169.imageshack.us/img169/3980/pict0149.jpg http://img202.imageshack.us/img202/271/pict0147rt.jpg http://img8.imageshack.us/img8/1148/pict0145vf.jpg I did the oven reflow on my 360 and didn't even give the wire any thought which caused it to melt in places, particularly the pointy spot directly under the fan socket. When I turned my 360 on the fans I noticed that it was really quiet but I didn't think much of it till it red ringed again after about a week. Turns out that the fans weren't spinning because the electrical tape that held that wire there melted and the wire came loose. The ends of the wire had melted and I had no idea how it was originally connected to the board. I tried getting it to touch various spots on the motherboard and manage to get "1" fan to spin(the cpu fan) but the other didn't. I tried playing for a while like that and after about 6 hours it overheated. So I took it apart again and tried to bend and maneuver the wire. I couldn't get it to touch all for points so I tore all of the plastic off so all of the metal was exposed. I tried wrapping it around the 4 pointy things and eventually I managed to get the one fan working again but not the other. I kept working with and now I can't get either fan to come on with it. What I want to know is why exactly was that wire there to begin with (I've looked at a bunch of motherboard and fan related 360 pictures/tutorials and I've never seen a picture with a wire there like that) and how to get my fan to work again. What is it like right there on the bottom of a 360 naturally?
Hi, it looks like someone has tried to increase their fan speed by changing the power source but has failed and they put it on ebay. To fix perhaps buy a talismoon fan and hope it was the fan that was broken but from the looks it isn't. Maybe try to return the fan power to normal by resoldering the port with images of the net. My advice is probably to contact the person you bought it from and demand your money back. Moten
I bought this 360 over a year ago and it had no problems till I did the over re-flow and melted the wire. The 360 itself is fine, I just need to know how to get the fan back to its natural state since I have no idea what was changed to begin with. I wouldn't know what to start soldering or where. Maybe if possible to get a new wire and put it there in place of the one that melted. Of course I'm not even sure what kind of wire that is.
The best advice I can give you without actually seeing the motherboard in front of me is test the fans outside of the chassis, by themselves and make sure your fans are actually working (may require a bit of surgery). If it happens to be bad fans, replace them. If they work, then I would recommend removing the wire entirely, cleaning the board up (lightly use toothbrush with alcohol) where the tape was and also check for whiskers (tin whiskers that may short circuits), and maybe try using this guide for reference to start that mod from scratch.
The fans are fine. They stopped working when the wire connecting the 4 points under the fan socket melted. I saw that guide before I came here but it doesn't show the bottom of the board so I couldn't use it. What I wanted to know is how to restore it to the way its supposed to be or where I can get another wire to replace the one that melted.
So if you take the wire completely off the fans dont run at all? I guess that'd be what the wire was for (instead of the 12v mod, just providing power to them for whatever reason). That wire either wasnt (or shouldnt) have been connecting all 4 points though because 2 are ground so if you connect the power directly to ground then you have a short circuit. If it doesnt run at all without the wire I'd just go ahead and do the regular 12v fan mod with solder not tape (you definitely do not want wires coming loose and touching anything in there). Any kind of similar gauge stranded wire should be fine
Now thats the kind of reply I was looking for. Do you know where I can find a diagram of which wire are power and which are ground? Also, if I just took the wire off completely will it start working again since it wasn't supposed to be there or would I have to solder and unsolder some stuff?
If the fan doesnt work and you say it's connected to all 4 points on the fan connector I would take it off immediately If there is a short circuit then power bypasses the fans and runs straight to ground so your fans wont spin. If the fans still dont spin without the wire llama has a good guide for the 12v mod (though I would do both positive wires, not just the one): http://www.llamma.com/xbox360/mods/360-12V-fan-Mod.htm
The fan works. Well one of them. When I touch the wire to the two point near where the DVD drive power socket is like it was before the tape melted one of the fans comes on the. The reason for this is because the other end of the wire is soldered to one of the point under the fan socket. I need to figure out which other point is need to get both fans working and I need to get a new wire to connect the two because there was a small seperate wire there before and I lost it. That why I need a diagram of how the it looks under the board normally where the fan socket is. I need to know what I need connected.
Can someone make a picture or something that shows which one of the other 3 points I need to connect to get power to both fans?
