Well the room the projector sits in doesn’t have aircon and it can get warm on hot days. I don’t watch movies during the day but at night I won’t use it if the room is warm.  

$150 Extraction fan as have in bathrooms frank ..  done ... 

 

put a temp monitor in room so can keep check though the extraction fan near jvc will extract air make sure somewhere in that room is air inlet from another room that’s at ambient/conditioned

Thanks Al I’ll have to look into that. I have a thermometer in the room and it reached 31 Deg in the room during the day when outside hit 39/40 Deg.

I do have a shelf put in my room from my wall which is 550mm ( unfortunately Sony made me do it ~ another long story ) not happy to be honest about it.

If it’s in the room I noticed last night measuring the base of the projector to the back was only 430mm.

Hi frank wouldn’t be 31 deg let alone 39-40 in the rest house so extracting from room, sucking air from what is in 20s in room adjoining am sure will keep your projection room in the 20s

 

$150 sparky would put an extraction in . Simple slot grill in door of projection room or simple vent in room to room adjoining would take care of cool air in :)

The port hole where the projector projects through is open which cold air comes from the theatre room.

Our American friends tell me to put a glass in the port hole ??? Why would I do that. Why go through another glass when projecting.

Only reason to do so would be to help with noise reduction, if that's an issue for you. Important to use optical quality glass, not just any old crud.

That’s okay then no issue with noise on my end.

That’s good just putting in the adjoining room would be further enough. Mine is couple metres back and don’t notice noise wise. These are quite quiet projectors anyways :)

Ive been told because my projector is close to one side of the wall ( right side ) the heat from the front will travel down the back which then could be sucked by the projector from the back. Ive had 3 JVC their before no issue.
For the time being I went to Jaycar electronics and rigged up 3 fans by trigger to push the air back to the front.

I have 200mm distance from the front wall / port hole. 200mm from the ceiling to my projector. Apart from the right wall everything is wide open.

I know Craig peer runs ducts off fronts, not sure jvc got a feeling it’s his high lumens dlp 
 

meh ... if worried air flow wise just rig up some thin shredded paper strips soon tell you in a flash If any sorta streams of air moving around. My bet the paper streams don’t even move ! 
 

as long as ambient temp is in 20s I personally wouldn’t bother :)

 

ps what else in the room. Is it an equipment room ? Few power amps and things ? Few kws Generating 50% Into heat will add heat load ... if a case I for one would be adding an extraction fan still as minimum :)

 

can locate it right above the jvc if concerned :) hot air rises ...will remove any of that in a flash :)

Will have to run extraction fan. I have 2 Rotel RMB 1585 and a 1552 mk2 and marantz 8805 all with cooling fans above pushing air forward towards the door.

Honestly pop the extraction fan in the ceiling and a slot grill on the door and won’t have any cooling to be worried off :)

Interesting thing with way air Flow works is to generate air flow it might actually be better with extraction fan to close the door ... feel the amount of air draw then from under the door or through slot vent on it :) anyways can experiment once get fan in and can see effectiveness looking at room temps :)

guys if into Bond films check out the latest release Daniel Craig UHD collection... I have only checked out the first release in Casino Royale that is first time on UHD. Now I have seen this movie many a time over the years on prior JVCs, Sony and Epson and on blu-ray release and wow is all can say on this one especially with the jvc n7 ...the richness of colour and detail the n7 is rendering with this is absolutely THE best I have ever seen this movie. Have to consider this is a 2006 production and only with a 2K intermediate and yet looks so stunning. I was just sitting there watching thinking just how good is this ! the JVC n7 is indeed giving me quite a re discovery on many great movies I've very much enjoyed in the past !
