Sorry, I'm a bit bad at understanding descriptions. Could ya tell me which pin numbers the yellow, red, and black wires go to?

ok if plug the cable in the MB 10,12 red yellow and # 4 black .


P.S. I have been messeing with it if I put the yellow wire "12v" to my PC power supply and the red to red on my PC "5v" and black to black on PC "ground" and plug the LCD in I can run the fan with it and control them.

Ok then, that's exactly what I've been trying to figure out. lol Run the blacks to any ground, the yellow to a 12v on the motherboard, and the red wire to a 5v on the motherboard. Then it should work just like it was intended.

The fan plug on the xbox 360 MB is only 5V. I check it with my FLUKE both red and brown what’s up with that. I could gust hook in to that for ground and 5V then get the 12v from PSU Know ?

That fan plug changes voltages depending on whether or not you have the 360 at the dashboard or not, and depending on what temperature the CPU and GPU are. It changes between 5v and 12v. You can use the black and blue wires there for the ground though. YOu can get 12v at the PSU plug on the underside of the mobo, and you can get 5v on one of the USB ports or the various transistors that have been accepted as 5v supplies.

Ok! I have probed some spot on the xbox 360 MB board with the fluke. I found pic's of on this site about 5v and 12v spots the ones that say there 5v but none are. Can you post some pic's, and show me a good safe 5v point on the USB ports. I'll just take power and ground off PUC plug there are some good pic's on that.

Sorry it took me a bit, I was having a rough day. lol Here's a pic that shows where you can ger 5v from under the USB ports.


Property of Aweirdguy.

Hope that helps!

Ok.

The problem I have is that my original Fan Connection (the one on the Motherboard doesnt allow any power to go through the Red wire) so for the past 5 Months I have been using the 12v output into the Red wire, with the Brown wire remaining in its normal place.

Now, what Im peeved off at is the noise!

Is there any way I can get the Brown Wire to supply both the Brown and Red wires with power to power my fans, or should I go for the 5v output, and if so, will it be significantly quieter?

Ignore my last reply.

I tried to edit it, but it wont let me:

I had a problem with my Fan. It stopped transmitting power through the red wire.

So I have connected the Red wire (by extending it) to a 12v source located underneath the DVD-Drive.

Now, the Ground is still in the same place as it was originally (the only wire I cut was the red one.)

If I move the Ground wire to a 5v source, (I particularly like the big strip in the picture below) it will reduce the 12v fan down to 7v, thus making my machine quieter, yet still will perform the same?

Or can I make my Brown wire power both the Red and the Brown.

Excuse my crap knowledge of this.

Ok, sounds like one of the fan transistors simply blew. If you try to run both fans from the brown wire, it'll blow too, so you should stick to other sources of power. I suggest running it at 7v. 12v in, 5v out, and it should by all means perform just fine, as long as your 360 wasn't having any overheating problems to begin wtih.

Thanks ! Gokussj5okazu



All good up and running with full controle of fans.

That sounds about right. I had a 360 before hand from Cash Converters, but I took it back as soon as one of the fans stopped. lol. Got me money back and got a brand new one. The same thing happened and I was well miffed!

So, Ive posted pictures in this topic, and also a little more detail so if you can help any, then that would be really appreciated. All I am really looking for now, is a safe 5v spot so I can keep using the 12v spot I am using right now. And with the fan being a Talismoon Whisper fan, its got LEDs and the Fan, so I didnt really know what specification it needs and what category it fell under.

I hope this doesn't sound too noobish - I am not inexperienced with soldering and such and I have successfully made the 12v stock fan mod. I used a 25w needle point iron. I originally wanted to use the 12v source that is under the MB where the power supply connection is, but no matter how long I hold the tip to those connections, it just doesn't make the solder flow. Am I missing something? Should I use a more powerful iron? I did manage to get the 12v source from the original 12v mod tutorial. The solder reluctantly stayed on the connection and I had to gingerly tape it with elec. tape. Any advise would be helpful! Thanks.

With thanks to Sinister Slipknot, I got mine to do it perfectly.

The reason your Solder wont ment it is because Microsoft use Grade A materials, basically, Industrial Strength.

So what You have to do is dab some solder onto it, let it dry, then solder the wire onto the dry solder of yours. Its should stick OK then.

All the best. I have done mine so any more help you may need, I can help you a little.

Is there any particular type of solder that will 'stick' better than others? I use a non-lead containing solder and it seems to have very weak holding ability. I did get it to stick, but i am afraid the connection will come loose quite easily. Oh and thanks for tha info!

Hey, i have a question, i took my xbox 360 stock fans off, cut the 4 wires, and i wanted to use another source than the machine to give them power, the thing is that i've tried them with 2 different sources and the fans don't spin(with 12 volts), i don't know if i did something wrong or what, but the just won't sping, i'm driving myself crazy, don't know what to do.Was i supposed to cut the 3 wires off? or did i broke them, both coolers have 2 wires, i don't know why it's not working, any help/advice would be appreciate it! Ignacio

Hmm odd predicament. Maybe you had them wired wrong? The red and brown wires should go to 12v, the black and blue to ground. Is that how you have them wired?

Get some flux... smear the flux on the area you want the solder to stick to... dip the end of your wire in the flux and let some solder wick up into/on it... hold the tinned wire against whatever your soldering the wire to (the area in which you applied the flux) and heat - voila! strong connection.

ok can someone tell me what the 12v mod is for? how does it help the xbox 360s performance?

The 12v mod causes the fans to run faster, therefore moving more air, and cooling the 360 better.

There are any other solution without soldering to the motherboard? I´m a noob and i don´t feel comfortable soldering.

Hello all,

I resurrected a 360 using my own jackleg methods of clamping down on the CPU and GPU (don't ask how, it was very un-scientific) and wired the fans to a 12V source. It has been working fine but as we all know it is very loud.

I was thinking of just dropping the voltage to 8 or 9 volts by adding a resistor. Does anyone know what value it should be? I don't know how much current the fans draw at 12V so I figured I'd better ask around.

I have both fans wired for 12V and wanted to keep both of them running faster than stock. I have heard of the 7 volt mod but really thought I might need more voltage given that this unit had heat sinks clogged with dust and got very hot.

Any ideas would be appreciated.

you could have the fans running on the stock speed but also add an additional fan to the heat sink which would keep it cooler.

Just like the one below:

I'm with you on this one. I'm afraid I'd bugger up the full system my doing something i shouldn't.

If we change the X360's stock fans voltages from 5 to 12, fans life cycle will reduce. will this make problems in long term?

Hey thanks that helps keep the temp down a lot and i did it myself and I'm only a 14 year old i found something that works better i removed the xbox 360 stock fans and so there is an empty space and put the intercooler from nyko on back its very loud but very good and you should try it

I cant see that helping at all, they are outside the case and dont seal. if anything its getting warmer.

It does work better though this is my second day of leaving it on and it is fine so it works for me


o ya and it does seal so its sucking a lot of air, it also has three fans running a 12 v

camster07 - 3 small 50mm fans bro. how would it be better than if you had your stock fans installed and the intercooler? you would have internal fans pulling air and your junk intercooler (5 fans). show us some temps with and without to prove your theory.

not trying to bash your idea, but i just dont believe this is any better..

I have a big problem, I did the 12v mod, but now my power supply is shot. But i was able to play for many hours before anything happened to it. I just tried to turn the system on this morning and nothing happened. (which scared the crap outta me =( .. ) I know it's not the system because i tried the power supply(brick) on another system and it still wont boot.

My concern here is that by doing the 12v mod it may put to much stress on the power supply.

And no i didn't screw anything up, I'm an engineer with some minor electrical background, so I do know what I'm doing.

But in any event the fans only pull .4 Amps a piece. And off the 12v DVD wire I don't see how it would mess anything up in the power supply. Seeing as .8 amps are taken away from the draw of the original plug but added to the 12v supply. Which in turn if anything would go wrong it would occur within the system itself and not the power supply.

If anyone has any ideas, or comments, or if you think my power supply was just old,.. please let me know.

Oh and btw i do agree that the 12v fans are really loud,. but if your turn up the sound system,.. well, i can't hear the fans anymore =) and i think thats better than a system that freezes up all the time.

LOL, n/m guys.... I beat the crap out of the power supply agianst my desk. And now it works fine again. I have no idea what happened,.. no idea how i fixed it,.. but it works,.. thats all that matters,..

the funny thing is that the red light never came on on the power supply. Oh well
Thanx

I just did that.


It helps the cpu but not the gpu.

According to this post, there is no meaningful difference for GPU temperature whether stock fans run at 12 (11.7), 10, 9 or 8 volt when airflow divider is being used.
So if I want both fans to run at 9v (to be more exact 8.7v), then I should cut the BLACK and BLUE wires, then solder them together, then solder a third wire to that, and finally solder the other end of the third wire to the DVD 3.3v power source*?

*DVD Power is not safe? What 3.3v power source would you suggest?

Quite interesting to see that you put your motherboard on carpet.

i see something between the mb and the carpet.

hi guys,sorry for asking a help on the first post. i think i have f****d up my 360. last night after seeing the 12v stock fan mod i did it and got the both fans connected to 12v source. now both fans are running at maximum speed . i have checked it. but the problem is as soon as i turn on my 360 and as it boots up it starts showing two red lights section 1 and 3,which i think means that its overheating.i touched cpu and gpu heatsinks which were quite cool.how can 360m heat up just in 10 seconds after starting?is it a bad solder which is causing the fan to not run properly or is it just temperature sensor malfuntioning which is causing the error code to show up?by the way for 12v power source i used one of three points below main power connector.please someone help.

I just did this mod and wow.. it works awesome. The CPU heatsink doesn't even get hot anymore.. it gets lukewarm! One question though, is a 26awg wire good enough for the 12v? Thanks

Looks like this mod is a bad idea now, due to the new wave of MS Live bans. Personally, I have my system apart and 2 large fans directly attached to the GPU and CPU heatsinks, running quietly.

-Erich

I really don't think this fan mod can get you banned from XBL, even if they can detect it. You're not breaking the Live TOS, you're just voiding your warranty.

my cpu side fan is not working , i have even tried replacing the stocks fans with other fans which were working fine in another xbox but not with this one.So i thaught doing 12vmod will be best.But i am unable to see the pictures in the tutorial , anyone can fix this for me.

Regards
Chain

LOL i got the same problem. I need pics!

Hey guys, will 22 gauge stranded wire work fine for this mod?

I'd like to make a suggestion. It seems that the best way to stop bricking your 360 is to use Fuse wire to make bridging connections (form it into a small loop like a horseshoe) and an inline fuse holder with an appropriately rated fuse. This will stop shorts and pulling to much current from the system and for what it would cost, would save you a lot of money.

I wish I could post some pictures of it, but...What I did to complete the 12V mod was what a good percentage of you are doing. I spliced both the Red, and Brown wires and wrapped them together. Then, I took some random wire I had lying around and tied it to the end of the Red and Brown, then taped the connection with electric tape.

Then, I spliced the single wire of the DVD drive, and connected it to the extension wire, adding more tape to both connections. Plugging it in showed a small increase to the noise of the system, perhaps cutting the fan grill helped with that. But anyways, the fan speed is dramatically increased and my system is "rarely" (and I am able to use this word very lightly) warm. The base of the motherboard was my main concern, and it's almost never warm.

To clarify for anyone who doesn't understand my interpretation of the word, warm...Warm means 120 degrees, warm in my usage after the 12V mod, means 100 degrees.

The figures, of course, are all estimated, and not entirely accurate. But for the small addition of "some" background noise, the drop in temperature has been HUGE.

#EDIT# For anyone that needs help doing this mod...http://youtube.com/watch?v=zTxcYDKGCYw I used this video for a reference to the wires that I spliced.

However, the video is slightly outdated, pertaining to the Falcon version of 360s (I believe). And the reference of the wires that are connected to the fan in the video is wrong, you need to splice both the Red, and the Brown...Not only the Red (like the video shows).

Good luck!

Can someone please provide pics for some reason the pics arent working on the front page. Thanks

Hi guys

My xbox is running the 12V mod, but it's just too damn loud and like other have said will reduced fan life. Question is what can I do to make the fans run at say 9V being a little quieter and not sounding like a jet?

9v regulator my fans runs @9v. and that is perfect cooling vs noise.

Where have the pics gone!?!?!?

what do you mean the single wire? I have 2 sets of wires going to my dvd drive.. one is the sata cable..
and the other cable has about 10 wires going into the dvd drive (and im sure thats the one you cut) just out of those 10 wires you can just cut any one of them or what?

Thanks
