Original fan is 12v?


Recommended Posts

Hi! I just picked up a 1.0 that a guy was selling as not tested. It had never been opened and you could see the dust from the side of the case, so I decided to open it up to clean it and check the clock capacitor before actually testing it.

The thing is, when I took out the fan the sticker on the bottom was this one in photo. And the tiny cpu cooler fan seems to be 12v too. I've ever heard that og fans were 6v, but as the fan I removed from this 1.0 was spinning like it was new, I tested it on my TSOP flashed 1.2 and it worked just like the previous one. 

So are the og fans actually 12v while the system gives 6v, or is the 1.0 being different? If it was so, a new 70mm 12v fan shouldn't need to be set to much more percentage than the original.

The fans are both 12v. The tiny GPU runs always at 12v. The CPU Fan is controlled and the speed is variable.  And all fans are the same (12v). I have seen 4 different types of them but again, all are 12v.

Thank you, that clears out everything

If you are going to change the rear fan just be aware that some of the silent type fans don't move enough air to cool the Xbox properly unless you run them full speed, Then they make more noise than the stock fan.

Are you sure about this? To my knowledge the GPU fan doesn't actually receive the full 12V, it's closer to 6V as stated by op. This means it doesn't spin at full speed and you can't use a 5V fan because it will eventually fry due to over-voltage.

The GPU fan on a version 1.0 is running on 12 volt, The CPU fan has a transistor to control the fan speed and the voltage can read between 5 (10%)to 12 volt (100%)

The GPU fan connector is also a good spot get power from on a version 1.0 - 1.4 to run LED's from as it is a switched 12 volt straight from the PSU.

@sweetdarkdestinyI was wondering if you had verified it yourself. I have seen many claim it's ~6V but haven't gotten around to checking it. It also doesn't need to move much air because the heatsink by itself is almost enough. And if you change to the slightly larger GPU heatsink there's definitely no need for a fan.

Well, since you're sure, and SS_Dave is sure, I don't want to be one spreading misinformation. Unfortunately my multimeter has broken down, so I couldn't fully verify, the best I could do was an observability study and indeed it would seem to be 12V or close to it. Thanks for setting me straight!

      There was recently a person on reddit who uploaded an Xbox game trailer DVD, it had high-quality video of different trailers, and I was wondering where I can get more of this sort of content.
      There are plenty of Youtube videos but they usually suffer from bad quality, so I’m wondering where I should be looking for the raw unaltered stuff.

      Hello i wanted to repaint my original Xbox system because it has deep scratches on it.  The one sticker on the bottom that is in Gray that says Xbox Video Game System i tried to remove and not damage because of the screw under it. However i could not save it. I was wondering if anyone has stickers for it. Or make any OEM stickers that will work Where can i find one at?

      Hi everyone, I have a tsoped original xbox ver. 1.1 motherboard, clock capacitor removed, and running indi-bios. In rare occasions, when I turn on the console..I get a flashing green light with no image nor sound on screen. What can the green flashing light code mean? I tried unplugging the console from power strip, pressing/holding power button for 30sec. and when I re-connect the console and turn it on..I still get a flashing green light. But usually the console turns on fine. I'm not sure if it's a bad ribbon cable, or a bad sata adapter. I do know I have a foxcom IDE ribbon cable, and I do have a good quality sata adapter. The capacitors on power supply and motherboard look fine, they are not bloated, nor leaking. (capacitors look new)
       
      Thanks in advance
