Acceptable Cabinet Temperature

[david.miller]

I've just taken delivery of a wooden cabinet to hold my AV kit, and I'm a little concerned about the temperature. I've read Deepcore's useful thread on fitting cooling fans to a cabinet (http://www.avforums.com/forums/showt...php?p=3528487), and am considering doing the same.

However, I don't know much of a problem this really is for me. I only have a Sky HD box, Amp and DVD player in the cabinet, and they do get fairly warm with the door closed. However, I've drilled a couple of extra holes at the top and bottom - and obviously it has to be a bit warmer in there for convection to occur. My wife is convinced I'm worrying about nothing!

Does anyone know what sort of temperature AV components can sit in without damage? That way, I could monitor the temperature before taking the plunge and fitting fans if really necessary...

Thanks,

David

Glad you liked the thread

Have a look through your instruction manuals, towards the back they normally have a temperature operating range. At a rough guess try the lowest “High” valve across your kit and use that as a guide.

Hope that is of some help.

Thanks, Deepcore - good idea!

My RX-V540RDS manual doesn't mention a temperature range as far as I can see (http://www.yamaha-uk.com/pdf/owner_m...X-V540RDS.pdf)... but it does mention overheat protection circuitry so I guess I only need to get really worried if this activates.

I'll have a look in my Sky HD manual this evening, to see what it says.

Incidentally, the amp manual says "Allow ventilation space of at least 30 cm on the top, 20 cm on the left and right, and 20 cm on the back of this unit."

Are they serious? Does anyone have this amount of space?

My RX-V620RDS has about 5 cm clearance at the back, for cables. However I have not placed anything onto to keep the vents clear.

Mine's similar at the back, and probably has about a 5cm gap above it to the shelf above. Unfortunately, the surrounding air gets pretty hot, so any convection within the cabinet doesn't cool things down much.

Do you have much space between it and the shelf above?

Incidentally, for the record, the Sky HD manual says the maximum operating temperature is 45 deg. C. I must try to buy a half-decent thermometer tomorrow!

Silly question:

1. I can see the picture (and you have much more space then me)
2. You have cooling!

Doh!
