Does anyone know of a 5 volt supply on the t-r42 (or possibly k-r42) board that only provides power when the device is on? I want to do a fan mod, but I've gone over it with the multimeter and can't find a source that goes off when the device is turned off but still plugged in. Even the usb ports still have power going through them! Best I can find is the 3.3v used to power the leds. I suppose I could use that to turn on a really tiny relay!

I'm going to buy this http://www.****.co.uk/itm/350961331112 and risk £2 in the hope of it working. -
In case anyone comes across this thread later: the relay was small, but too big to fit in this case. In the end, I just connected into the power connector soldered onto the board and it works fine, I just have to remember to only plug the box in when I'm using it. I've used a 12volt 4mm fan and it runs with no issues at 5volts. It's nice and quiet and keeps my board cool enough to run at 1.8ghz with no issues.Originally posted by SANGER_A2 View PostComment
