Xbox 360 12V Fan Mod
By: ClickClick 5
Here are three easy modifications you can do to your 360 to make the processor
run 22 degrees cooler, the graphics run 10 degrees cooler and the co-graphics
run 4 degrees cooler. (Temps are in Fahrenheit)
||Make one fan or both fans 12V. (I chose to do
just one, the processor fan)
-The RED and BROWN wires are the positive ones. The BLUE and BLACK
wires are the ground. I just cut the brown one and soldered it to
another piece of wire.
||-Then I set out to find a 12V source. (An easy
one to find) This showed to be a very
respected 12V source. (I recommend this source)
||Then I placed the cooling head on the co-graphics
chip. (You can also see the 12V
wiring better here)
||The final mod was the FOIL. I did not like the
air-flow over the graphics chip, so I
fixed that. I placed foil over the head to get the air flow to pull in
more towards the front
of the chip. In the end, I actually cut the foil off below the line I
drew here. (This is a very
nice cooling mod for the graphics chip, the air can still cool the DVD
drive and get
better air flow on the graphics.)
-These three simple quick-mods can keep your 360 running
cooler and longer.
Brief interview with CC5:
Q-Why do you recommend that 12V spot?
A- I looked around for a good 12V source, that could be accessed easily. My
original plan was to solder the wire to the underside of the board, where the DC
power comes in. But due to some problems with wiring and the spacing of the
connectors, I just decided to find a spot up top to solder onto. The source I
picked held constant while on Live (both wired and wireless), both kinds of
games, both the memory card and the HDD. So I assumed it would hold out...and it
has for four months now.
Q- How did you measure temperatures?
With an temp gun. My brother does a lot of R/C car stuff and he had a temp
gun that he uses to check the temp of his nitro car's engine.
I aimed the beam at the center of the GPU heat sink after it had ran for an
hour. (In the dashboard) Then at the bottom of the CPU cooler, the copper base,
I aimed the laser at that base. So I'm assuming the temps are correct. His gun
seemed to be calibrated correctly. Yet altitude, humidity, air-pressure affect
all the temps. I live in Denver CO, so the results are different for me then
they are for someone in California.
The foil thing came after I was getting ready to put the system back together.
Best part of the small mod right there. More air to surface ratio. Plus with
enough area to cool the bottom of the DVD drive.
*UPDATE* - The one small part I left out of the tutorial was after doing the
mods, I used MadDog Arctic Silver 5 for the heat compound. This assured
complete contact and heat distribution for the heat sinks.
-Oh, and thanks for the
mini-heatsink from your site!
||You can also pickup 12V and ground at the DVD
drive power cable. If your not comfortable soldering to your motherboard
this is a great option
||To keep fan noise in check while increasing the
flow we keep it reasonable by using a voltage regulating device, the
power delivered to the fans can be adapted to about 8V which appears to
be optimum for a 360 with both fans wired.
