2 fans sucking air out, or 1 fan sucking air in, 1 sucking out?

Don't bother attacking my English, I've never had anything but As throughout HS and university. It's not at all what you said. Did you even read what I actually wrote? Let me quote a part:

The denser the medium, the better the heat exchange (for a given material). That's completely opposite from your saying it will get hotter.

ace3000_1 is right, however, that any difference is going to be very small unless you have a compressor instead of a regular fan.

Right if the projector box is pressurising that means in itself that you have a bottleneck, you are pushing air in and its staying there longer than necessary because your exhaust fan can't cope with extracting it. You will have a pressurised box with more ambient heat because of the air density (and poor heat exchange if thats the term you really want to use). I don't think that your term 'heat exchange' is even really relevant to a fan bowing in/sucking out system. Maybe you are talking about heat exchange between the air in the box and the outer casing. In which case I doubt that will do much to cool the ambient temp inside even if you had an aluminium case and huge heat dissipating surfaces on it.

... up to 100 CFM which allows the blower to dispense large volume of heat....


sweeeeeeeeeeeet


also, there are water cooled PC case mods around, if they're using them for a PC, must be safe enough.
