12V bridging confusion ?!?!

[Max_Kreeger]

Hey guys,

I was given this tutorial to follow:

http://forums.xbox-scene.com/index.php?showtopic=637955

to bridge the transistors so it makes the fans 12v. Now my board is a V1.0 Xenon. Now the problem is...do I have to do what it says on both pictures or just one picture ?

I'm thinking yes...just need confirmation.

Thank you
Max

You dont have to do both pictures, I believe the picture of the top of the board will 12v the GPU side, and the botton will 12V the CPU side of the fan.  If you want both fans running on 12V then you need to do both.  In the second picture there is a red jumper drawn in that is hard to see, so dont forget that.

probably the coolest thing to do is use 2 dpst switches, one for each fan that allows normall operation, and 12V operation.

I havnt done 12V of fans this way, I have only hard wired them to the 12V source.  If all you wanted was 12V all the time than hard wiring it is much easier and safer.

I done both pics, and both fans are running at 12v (noisy as hell). What do you mean by safer ? Safer as in not getting banned or safer as in not screwing up ?

Thanks
Max

EDIT:

I have 3 fans now all together running at 12V, recommended ?

I believe that you are doing the very same thing, either way you do it.  either shorting those parts or soldering to the 12v source, electrically speaking is the same thing. 

The only safety issue is soldering to components, solder splash, wrong spot, ect. the straight 12v connection is more of a fool proof way to accomplish the same thing.

The advantage to the way you did it is that you just add a couple jumpers without messing with the fan connections, so it is easier to undo the mod if need be.

Phew...I thought you meant unsafe as in getting banned. Well I've been on LIVE and nothing, lets hope it stays that way.

God dammit...how many times have you helped me and I've never gotten the chance to return the favor, you know too much lol.
Thanks again for the info
