So after doing the 12v mod for one of my friends 360's I found that it drops the temps drastically. So I was wondering what my dev's temp was and I was shocked, mine was higher then his before the 12v mod on his. So I wanted to take some pics of the led that is on the board of mine anyway so when I took it apart I decided to do the 12v mod and see what the temps would go down to, and well I was impressed needless to say I'm keeping the 12v installed, I may add the new style heat sink as well since that also lowers the temps even more I noticed on his XBR'd zephyr Also does everybody else have an led on their kits close to the fan shroud that activates when the console is turned on? I tried to put an led on a retail and it doesn't light up, and the spots are there on the retails just not sure why it doesn't turn on the led. Hawk
Yep, the 12v mod results in a very dramatic change. I noticed that on a retail falcon I've got, sounds like a jet engine, but it's crazy cool. Maybe once I break the seals on my kit I'll 12v it too. -Doom
I did a rather disturbing mod on a failed Xenon (3RLOD): The guts look like this: The resulting temps are: CPU 67.6C GPU 45.1C EDRAM 44.2C Motherboard 33.7C Didn't 3RLOD again ever since..... Pretty cool, huh ? :lol:
Well thats a little cooler but the 12v mode would make it alot cooler, I'm prob going to open my kit and undo the 12 mod, and then just use the software version to turn them to around 80% i may do 100% it's just so loud ya know.
It *IS* running at 12v. With the two original fans only for the CPU and an new one for only the GPU. The CPU heatsink on the GPU is what make a already failed motherboard be reliable once again. It won't last three days running on the original heatsink. That's a "reasonable" way to attempt reviving a dead XeDK.
Oh haha, I didn't know you had it at 12v. I'm hoping my kit doesn't rrod on me, that would suck. But I don't use it that much so with the 12v mod it should be fine for the 10-20 mins I'm on it every couple days.
You just did the 12v mod for no reason. There is an xex that patches the fanspeed to 100% one time run only.
No I didn't. I did the 12v mod when such application did not exist. Also I have no reason to tinker with complex software if I am going to service a failed console. Installing a hard wired bypass is the less effort/more logical solution on this case. The program in question is very useful if you don't want to open the unit. Not my case. :thumbsup:
You pick an XEX, patch with some PPF tool to "program" what you want the speed to be, then you have to "feed" it to the box through some removable media. To hardwire 12V I just remove the fan control transistor and put a bypass jumper on top of it. 100% fanspeed without option for removal. If I removed a board to "heatgun" why not do that ? I then don't need to bother with "usual places" to download a XEX, I don't need to bother with XEX patching and so ... Well it's a personal option. If I can solder, I will solder. It's my nature... :thumbsup:
To change the fan speed with an XEX, you download the XEX, put it on your Xbox, launch it, and then the speed changes. I don't know where you're getting this "patch with some PPF tool to "program" what you want the speed to be" stuff or the "you have to 'feed' it to the box through some removable media" thing either.
I mean I would need to put it on somewhere the XBOX could load. The package I saw had fixed speeds so if I wanted anything different I would need to apply PPF patches to the said XEX (It's on X-S and xboxhacker if you're interested) All the hassle with software goes down to a single blob of solder placed on a strategic point of the motherboard. And then there's 0% chance of another POS (Piece Of Software, please don't misunderstand :thumbsup completely turn the fan off. This is why the fan speed program was made anyway... To fix damage made by some software programmer gremlin ... :lol: And I don't think there's much more to be said about this... I can say that putting the CPU heatsink on the GPU completely fixes the issue as the console on the picture is running for months now, JTAG-ED even.
There are now precompiled packages for different fan speeds... and its been tested alot, check out report from XS where even big block jaspers worked.
Yeah I just did the 12v fix because I know sooner or later it would happen, when I saw how much it improved temps I was like wow got to do that, and I know about the xex's now, but at the time I hadn't tested them, thats what I use on the retail kits, they work great. I'll probably unsolder from the board and then just use the xex, next time I get bored. The xex's are cool because if you are going to do a game session you can turn them up to 100 and not hear them cause ppls around then back to whatever when your just using it. Hawk
I just took a bit of a risk myself hoping not to brick my Kit :X, ended up working fine on a 256BB Jasper. I read about some people having their xbox spitout errors after patching and running it, but mine made it through fine. -Doom Edit: I left my kit on at the H3B Main Menu where it flies around a real valhalla for a little over two hours, here's a picture I took of the temperatures afterwards. Maybe later I'll go back to the 44speed and get a 'before' temperature picture. I'm curious as to how much cooler the jaspers run anyway.
If you really want this to be great get the whisper fans and then set it to 100. This way you have way quieter fans that doesn't sound like a cheap vacume cleaner and your not burning out your original fans.
One thing you can be sure. The fans are rated for 12V and won't burn/break from running at 12v since it's their specified voltage. MS runs them at a lower voltage *ONLY* to spare the poor users from the JET ENGINE noise... :thumbsup:
