Ok, I'm going to set a few things straight here, as far as what's true what's false, what parts to use, and how to go about it.
I've had my 360 since launch and have been doing pretty much nothing but fan mods because it gets extremely hot around here.
Number 1: If you draw too much current from the STOCK fan plug, the circuit will PERMANENTLY blow and you'll have to rewire the fan. DON'T DO IT! I don't know how much current it can handle, but 2 fans per side will blow it.
Number 2: The DVD drive wire is only suitable for small current draws. A handful of LEDs or a single fan WILL NOT cause any significant damage. I've been running mine with 15 LEDs and a 60mm fan for 2 years without a flaw!
Number 3: For the rear fans, either use aftermarket remakes such as Talismoons. If you prefer to do it yourself, use 60mm x 25mm fans. A suggested fan is at the bottom. For the front fan, a 55mm x 10mm is suggested. Anything wider than 10mm may hit the caps.
Number 4: You can draw as much current as you want from the bottom rear 12 source. This is the suggested spot for fans and LEDs as it can't be overdrawn and has circuit protection.
Number 5: Doing the 12v mod most likely will cause your console to be extremely loud, and possibly vibrate. Either use dampening cloth under and around the fans, get over it, or buy aftermarket fans. It's just something that comes with the extreme fan speeds.
If anyone has any questions I will try to answer them as soon as possible.
Fan Suggestions:
60mm x 25mm Back
Newegg VANTEC SF6025L 60mm Case Fan
60mm x 10mm CPU Front
Newegg Link Depot FAN-5015-B 50mm Case Fan
that 60x25mm fan is only 12CFM
i can fart with more force than that.
12cfm your really serious?
12cfm isnt going to get you anywhere.
you really want to cool the 360 properly then turn the fans around so they blow cool air in.
then take something, tape to test, and go around the edge of the heatsink and fan shroud/tube. this guarentees that all air is being sucked or blown, if you turned the fans around, directly thru the heatsink. im talking both cpu and gpu.
basically use or whatever to tape over any gap.
you can also use a thin sheet of plastic or something to cover the GPU heatsink, this will guarentee that all heat coming off the heatsink is pulled directly away from the heatsink.
stop and think for a minute. look at all the ati cards heatsinks.... did they simplu have the heatsink exposed and have the fan sitting there only sucking are away from the edge of the heatsink??
NO they completely covered the heatsink, and left the opposite end open. why ?
cuz this forces all heat out the exhaust.
do you see ATI cards bricking left and right ? no....
lets be honest here, the heat being drawn (or blown) over the gpu is piss poor.
have you ever touched the heatsink after its ran for a while,,, WOW, its no wonder xbox's are bricking.
that s far FAR from safe.
what you can also do is completely remove the side "mesh" of the motherboard cage.
that mesh doesnt have small enough holes to piss thru, alternately you can simply cut away a portion of it.
this will increase the air flow into the 360, or out of if you turned the fans around.
try it out
