With the s10,pay attention to the heat output from the processor.
It will vary according to the version of firmware you are running.
The latest firmware (12-10-2011) gets burn your finger hot.
When I first got mine,I disconnected the +12v wire running to the back
of the receiver and hooked up an old 486 cpu cooling fan and plopped it over
the processor.The +12v output sticker says 50ma,but it can put out more current.
My first fan was 150ma and it ran no problem,just too noisy for nightime bedroom use.
The fan will stay on as long as the power switch in back is on.
