Revision L M-tuner purchased the box last december, i did cut off the wires from the mini fan, connect those to green+ and white- from a usb cable.
Usb goes into the cooling pad which is placed on top of the box and the little white fan connector into the mainboard.
To get the cable out of the box without drilling any holes,i did remove the sata connector and the 56k modem.
So now when the box is powered on the fans are on to and when in standby fans are off also.
There is no need to get standby from the scart on pin8.
Not all clones having this standby on the mini fan conn. i guess only newer ones.
There is not much noise due the 5V but there's cool enough (the pad has 2 fans).
