Is there anyway of having this fan run 24/7 when turned on as all I did was to cut the red and black on both the 2 fans wire them and fit this but would rather have it on as its out its case as still to hot to touch metal case
Thanks for ya help

maybe u can solder the red and back wire to the power and ground part of the usb soldering points thats should keep it going all time
or at least as long as the ouya is on
Do you have a picture of this points

kinda if u look here ( http://ouyaforum.com/showthread.php?...ports-for-Ouya ) on the 2nd pic u can see where the red and black wires are soldered to red is the power and black the ground if u solder the red and black wires from the fan to these I'm sure it will work but i cant promise anythingQuote:

as I have four ouya's for xbmc around the house this is a well worth mod to do if you have a noctua fan
Thank youQuote:

I don't think there is a spot on the board that will provide constant +12V only when the OUYA is on.
Your best bet is a latching pushbutton switch or a normal toggle switch.
I've been thinking about this a little bit. I think I finally have a good use for the reset button on my mininess case.
It will be a latching DPDT switch which connects to the fan and switches between always on (connected as the above example) and auto (connected to original fan header).
Really, the fan setting should be available in the software...yet another short-coming of the platform.
this sounds like a good idea when u come up with how to hook this up i would like to know how and what u usedQuote:

You know...what would actually work better would be a relay that switches with 3V DC input. This would need a basic protection circuit.
Yes I like the sound of this as my fan is on 24/7 even when powered off but I don't mind as how hot these run is not good for there longevity
Sounds good when you get it figured out just let me know what parts i need and how too hook it up ^^Quote:

The fan will be on whet the unit is on, and off when the unit is completely off (it will run when the uint is 'sleeping'/standing by).
I consider this as a temporally solution, until the heating issue gets fixed.
Pic here.
You know whats strange. My Noctua fan is on 24/7 as long as the unit is plugged in even off. its strange I replaced it with the stock fan and the stock fan is the same. I checked the board and its fine. I have been playing with the kernel settings via performance control and its rooted but all is good. the hottest I have been able to get it streaming 1080P from my mac to it via ethernet is 138F which is ~ 58C so I am happy until my 3D printer comes and I can make a proper case.
