try opening your 360 again and double check that it is plugged in right

it most certainly is i check and double checked and checked again its clipped down tight clicked and everything one side spins and the other doesnt..

if possible, can you try swapping where they plug in. you dont have to test it assembled, but that would rule out whether it if the fan or not

Are you running LEDs or something else off the fans power connector? That will blow one of the two Transistors for running the fans pretty quick. Read here for more info on that.

Did you make sure the 8 small black heatsink screws are tight?

As for the Red lights and the fan going full tilt, what did you have the 360 apart for exactly? The fans running full speed problem is pretty common with a bad solder joint, did you heat gun it or do some other type of mod on the heatsinks at all? add any more wiring or solder onto the motherboard?

That just about proves the things in worse shape now than it probably was before.

You can try heating it again and see what happens, but I would't hold my breath. As for the fan dying there's not much point in dealing with that problem if ya can't get the 360 to boot. If ya heat it again and get it to start working, then you can either try replacing that Transistor or just run the fans from some other voltage source in the 360.

The 8 small black screws that hold the heatsinks in place, you had to have taken them out to get the motherboard out of the chassis.

does that 'sore spot' have signs of damaged? what if you plug the suspect fan into the other port?

Heat gunning the thing has only made the problem worse, you have one or more connections somewhere that aren't making good, if any, contact at the CPU/GPU/RAM/Southbridge or something has been outright torched from the heat. You can forget about the dead fan causing the issues, it's the other way around.

You can part it out, or you can roll the dice and heat it again, but messing with the fan is just a waste of your time, it's not causing the problem you're having.

that sounds about right. id recommend a thorough visual inspection of the entire board. but id say you might have canned a few IC's

they must have already been like that when i got it because i even bought an expensive heat gun to make sure it didnt get too hot and that it cooled properly..i have no idea why the fan went haywire...

oh well my little brother will be devistated that i couldnt fix it...

expensive = more power = more heat = more damage

sorry bro

not really...i could tell how hot everything is and the cheaper ones heated up way higher than mine and i saw ppl still using them in the tutorials so my heat gun wasnt the problem...just the 360 was junk when i got it (plucked it outta the trash cuz the company i work for threw it out cuz it was broken) i was just going to trade it for some credit and buy me some new games

Don't be suprised if it up and dies again in a hour, or a couple weeks, the thing may even run for a couple months, but I'd be suprised if it lasted any longer.

You can't plug the fan in anywhere else. I've already told ya what to do about it, it's either the Transistor is bad and needs replaced or scrap that whole deal and run them off another source in the 360.

thats your best option
