Where to Take Power For New Fan?

post #1 of 6
Thread Starter 
I've installed an exhaust fan over top of the heat-pipe heatsink of my Xbox 360, and have it currently wired into the 12V for the DVD drive. (I'm well aware of how "dangerous" many claim this to be) The main thing about this is that it's quite loud, and I'm wondering if I can wire the fan into the power for the other 2 fans on the back of the 360 without reducing the performance of the two. This is in hopes that the exhaust fan will too be controlled by the console as the two at the back already are.

Thoughts?

I would flip that fan to blow in . U already have an exhaust its in the back.. And taking power from dvd is not bad people always say that its bull****, even if u wire 10 fans it would be less than 20 watts. (No problem )if u have that new fan as an exhaust, it is fighting the exhaust already on the back of your consloe.so in the end it probally isnt doing much. Have it blowing in then it will blow on the heatsink and push the hot air out he back where it belongs. U CAN WIRE IT INTO THOSE PORTS BUT I WOULDNT I WOULD USE THE DVD DRIVE POWER SOURCE AND ALSO PUT THE REAR FANS POWER ON THE DVD DRIVE AS WELL, WHO CARES ABOUT NOISE YOUR BOX WILL BE COOL AND NEVER GET THE RROD... RROD IS CAUSED BY HEAT WHICH CREATES YOUR PROBLEM( COLD JOINTS,CRACKED SOLDER,WARPED BOARD ETC ETC..)- IF U KEEP IT COOL U WONT EVER HAVE THE RROD I GURANTEE IT . MY BOX RUNS AT 75 DEGREES F. GURANTEED WAY COOLER THAN MOST ......NO HEAT NO PROBLEMS

Idea....

Okay, well i have never opened one of these up, so cant tell you much.

however i am an experianced PC modder/builder and overclocker...

now what i do know is that the XBOX 360 is base on several PC components.

you can get fan reduction cables from zalman ,which have a resistor in the cable...

Zalman RC100 or The Zalman RC56

There are other ways.... but unlless you know what your doing i think this would be the safest route...

you would be taking the 12v fan down to either 5V or 7V with these zalman cables...

Everybody except Paradox needs to go back to school I think. Can't understand your guys' posts.

To answer the question at hand, a regular old PC fan will only take 5-7w or so at most. They really take absolutely no power at all (most say 0.5a on them, which would make them 6w off 12v DC). So you would be perfectly fine to run an extra fan off the same wires that go to the others that already spin up and down.

IIRC from my days of tearing Xbox's apart, there should be a +9 volt spot(s) somewhere along one of the edges of the mobo. Those are where i wired all my fans to when I modded my Xbox

i got the power by just sticking the wires into where the normal exhaust connects to

so mobo port > Stripped copper wire > Normal connector for rear fan to squish it in
