Yes, I'm a fan of the dB-4496 modular series.  But I was actually wondering if such a frame (housing two M*DA 824 and nothing else) could operate safely without the fan running, if the lid is off and the room is air conditioned.

To quote Groucho Marx; "If it gets any hotter, I could use a big fan"

I'd keep the lid on to protect from dust...

I've got a fully loaded chasis in front of me here and have never had the fan running.  Never noticed a heat issue (not hot to the touch).

IIRC, I was told by the folks at Lavry to not worry about it unless your in a very warm room or the unit is next to other gear that runs hot.  You would be wise to confirm those statments rather than take my word for it.  E-mail the tech support at Lavry.

Fanless,

Hi,

You can operate the unit without a fan, completely loaded (say 8CH AD or 8CH DA or any combination) even at elevated temperatures. The fan was put there for extreme temperatures. I have not yet seen a case where the fan is needed.

Open the lid, look for the fan power connector. It is marked J2, on an L shape board in front of the power supply (red and black wires). Pull the connector out, and you eliminated the fan operation.
