Gpu Fan 8.7v - 12v Switch Mod Options

[hevydani]

I've modded my GPU fan with a switch to go from 7v to 12v but am wondering if it would be better for me to just keep it as standard so the fan uses the transistor?

Should anyone want to know how I did this I'll upload a quick tut (couldn't find a straight tut online for this mod)

Well done a tut anyway incase people do wish to do this (I'd have liked one )


This mod is only for the GPU fan!

I done the 12v mod and while this did keep the Xbox cool, it was noisy as hell when trying to watch a film/play a game when the missus is asleep

So decided to do this quick mod to switch between the noisy 12v and 7v (as standard fans run at 5v which I felt wasn't good enough)


So, you will need-

A toggle switch like this one - http://www.positiveoffset.com/Parts/on-off-switch.jpg
Some wire
Soldering skills


You first need to cut the "-" wire from the fan (the black one), but leave enough so you can join it to another piece of wire. In the middle will do nicely.

Now, solder/join a length of wire from the "-" (black) from the fan itself (NOT the fan plug!) to the middle leg of the switch.

Then cut the "+" (red) from the fan, join this to a longer piece of wire and solder it to the 12v point as shown in the picture.

You now need to solder a piece of wire from the left leg of the switch, to the 3.3v point shown in the pic.

Finally you need to join a length of wire from the "-" (Black) from the FAN PLUG and solder to the right leg of the switch.


And that's it! Hope this helps someone!
