Noted, there are a few other forums perhaps more dedicated to thistopic, but this is my favourite group by far, so I thought I'd starthere. Besides, from what I've read on these other forums, the geek-factor plays a major role and, in most threads, assumes that every set-up, however small, should measure up to your typical digital, multi-plex, cinema experience!This just ain't the case for your average Jo!I'm an average Jo, and so is my pal/colleague/client. We areneighbours, running our own, separate, businesses, in the constructionindustry. Possessing different trade skills, between us, we often joinforces, to provide each other's clients, with a greater range ofservices, readily at hand.We also do a bit for each other, on our own houses, which is the caseright now...!He's built an enclosure for his flat-screen plasma TV and has asked meto do the electrical work, so he can power everything up, within thefalse chimney breast he's made, from timber studding. Nothingexceptional there, as you can imagine. There's a skirting-board-level,twin socket nearby that's on the local ring-main and its a smallmatter to extend this into the timber enclosure, and add the necessaryoutlets, where required, once I'd got from him how many he needed.However, knowing how clueless he is, when it comes to electrics, I puta few questions to him, one of which concerned the opinion, held bythe manufacturers of his particular model Plasma, with regards to itbeing encased in a cabinet and continuing to function normally,without over-heating!Next thing I know, he's handing me 2 small electric fans he'd boughtfrom Maplins, following the advice of someone or other.With no idea about their needing a 12V DC power supply (let alone ameans by which to control their activation/deactivation, according toTV usage and/or excessively high temperature levels) he's then askingme to hook 'em up as part of the installation!To quickly conclude an already-long post...We spoke. I explained. He eventually...

Most lighting transformers have an AC output...better PC setups) would be a better starting point if you decide you need active cooling.Have a look at : one (particularly appropriately named) passive cooling method is the chimney effect. When you have a long tallish enclosure such as you describe, you should get a reasonable air flow through it just using convection cooling. An air admittance vent low down, and an exhaust high up will probably draw a fair amount of air through once the space heats up. You could even experiment with venting the exhaust into the chimney stack (assuming its not used for a fire etc). A posh solution may be to have the top vents switchable - up the chimney in the summer, and back into the room in the winter.
