The "main" fan (bulb cooling fan) is a standard 80x80x25 12volt PC type fan. It is connected to the main PCB with a 3 pin plug, so it has speed monitoring.
This fan is easily changed with a standard PC fan (Papst would be a good choice).
The second fan is a standard 80x80x10 12 volt unit. This draws in air through the front panel (just overhead the Panasonic logo) & passes it over the PSU PCB & heatsinks.
Again this is easily changed if required.
The third fan, & by far the loudest on my unit, is just inside the air filter intake. I haven't removed this one yet, so I can't give much information on it. However, it is not a standard PC type fan, having a very different impellor configuration.
This fan cools the LCD panels & prism/mirror assemblies.
As you'll no doubt deduce from this post, I have had my AE-100 in pieces
I'm an engineer with Siemens, so well qualified to undertake such exploratory work.
I'm pretty happy with my knowledge of this unit now, & would say that this is a very basic simple unit. Apart from the LCD panels, there is nothing in there to warrant very high prices.
Also, to clarify something asked on another thread, there is no "hidden" serial port inside the unit.
I'll take some time some day & write a full technical report on this unit. If I have it down from it's ceiling mounted position I'll probably take some pics & post them also.
That one by the ait filter looks like a cage fan, or something named close to that. I have exhuast fans that look like that, they are supposed to move lots of air while being quiter reletive to another fan that moves the same amount of air. Would probably be tough to find a replacement.
