How to make the fan always on?

[arm206]

Is there a way to make the fan always running?
Do anybody knows a soft way, or a suitable +12V output on the motherboard?

Thanks in advice!

There's nothing as far as software or a custom ROM yet. Should be possible to go straight from the board to the fan if you are confident in your soldering skills, but I wouldn't chance it if you are not, heh.

I have access to soldering equipment sophisticated enough, and I'm bold enough to try it, but I can't identify the solder points on the board. (+12V, only on when the unit is on, and enough power to drive the fan).
Any infos about this?

I have no information about which points to use myself. I havn't soldered anything for a long time and I wouldn't dare to try my rusty skills on my Ouya, haha. I'm sure a more handy member will hop in here and help you out soon.

As temporally solution I took a generic npn switching transistor (with a resistor) and using the solder points of the power supply connectors (+12V and GND) on the motherboard and the +5V point of the usb connector I created a simple add-on circuit that switches the fan on when the usb port is getting power.
But I still hope somebody will show up with deeper knowledge about the motherboard.

Nifty solution! You should post some pics in case someone else wants to try something similar.

Very nice,i needed this mod. Thanks

Could you name a NPN transistor and the resistor value ?
If the 5V are from usb...when the usb port going standby the fan stops ?
