Thanks Alex - sounds like the direction I was heading in, as you can always turn the power down Any suggestions for a source of these and heat sink / fan type parts in the Brisbane area? I like to walk in and size things up when it comes to this sort of thing.

Thanks again - my plan is to have the heat sink mostly blocking up the gap where the screen once was, and seal it around with rubber or silicon. Nothing firm, just thoughts right now

Thanks again Glen - you can never have too much information, only too little
