First post so be gentle. I have just read this whole very interesting thread as I find myself in the same position in regards to wanting to add some sort of cooling to my AV enclosure.
Now straight up guys I'm very confused by what I actually need. Out of all of this discussion the one thing I don't want is it to be running the fans 24/7, to me I would just prefer not to have something running all the time unless absolutely necessary. Probably something that either comes on as the temp rises or when I actually turn the amp on. The amp will only be running when playing the dvd player for movies or music.
The other important bit of information is that I'm in Australia and whatever piece of electronic stuff that I buy needs to suit our voltage of 240V.
Now onto the cooling part of it. I had toyed with the idea of just taking the back off from the unit all together, but I'm guessing really that is not a good idea because of dust etc, what do you think?
I have only had this unit delivered to me yesterday and I have it set up in the workshop waiting to do the cut outs on the back.
The two different brands of fan that I have been looking at are Scythe S-FLEX 120mm Fan SFF21E and the Noctua NF-S12-/1200 and both seem to be highly recommended, what do you reckon?
As you will see from the added photos I think the amp (Onkyo 875) will be on it's own in one side of the unit and the rest of the gear will be on the other side. The other equipment being a Panasonic DVD recorder, Foxtel Satellite box, and a regular Pioneer DVD player. And in the narrow opening in the middle I will have an Xbox360 or PS3 if I can ever make up my mind.
In the last picture with the amp in it I had intended to have the amp sitting on the bottom of the unit but the knuckle on the hinge interferes with the width of it so I have had to have this silly bottom shelf about 75mm from the bottom, not the best looking, but better to find out now rather than later. The two empty holes will be for the centre channel and the sub woofer.
So without further waffling from me what should I be looking at? Do I need to cut some vents in the front along the toespace to allow cool air to be drawn in, or could I drill some holes in the bottom at the back corner to try and create some sort of chimney effect. Or do I forget all that because I will still have to cut some fairly big cutouts for cabling and hooking up of all the gear?
