OK Operating temps?

[upsized]

Hi Y'all! First time poster here. I did some searching but didn't find the answer I was looking for so here goes. TIA. Hope this is in the right forum...

I recently purchased an Onkyo 6200 HTIB and an Insignia 37" LCD TV. Both are in a corner cabinet with, the receiver on a shelf over the TV. There is about a 1 1/2" gap above the TV under the shelf. The TV pretty much fills the cabinet side to side and there is more than a foot of backspace behind the TV; there is about 9-12" airspace above the receiver before the "roof" of the cabinet; no ventillation out the back or sides of the cabinet.
Myconcern is that when running the tv and receiver at moderate volumes for a few hours, the air in the space where the receiver is is about 95*....

My question is- at what static ambient(within the cabinet) running temperatures can a receiver operate for hours and safely safely??
How about for the TV's air space??
Do I need to be thinking about putting fans at the back of the cab?? Or at what temps should that be considered??

While I know that this is definately not high end high powered stuff, it is all I can afford right now and don't want to cook it out of ignorance.

Thanks for any information, particuallarly numbers I can latch on to for reference as I'm going to be monitoring these temps.

Thanks again!

In general, it's best to keep the ambient temperature less than 85 degrees fahrenheit, but I doubt 95 degress will do any damage.

It would be best if you could cut a hole in the back of the cabinet near the top of the enclosure the receiver sits in to allow a path for some of the hot air to escape.

I agree with MDS, and personally would add as much ventilation as possible, IMO.
This coming from someone that has pancake fans on top of all my amps and / or receivers; except the Emotiva amps, they run cool no matter what.

Thanks for the input. Yea, what i was thinking was to cut a fan-sized hole at the top and back aspect of both the TV and receiver compartments, and if I continually get 90*+ readings I was thinking of this maybe???

uh, couldn't post a link but it was for coolerguys cabcool 1201-2 dual fan with 81-86* automatic thermostat

Thoughts?? Is 86* an accepted normal opp temp max as per this site or are this overkill??

Well I guess I'm gonna have to do something. This weekend after running the TV and receiver for many hours straight the air temps leaving the cab were 100-105* depending on where the measurment was taken.
And on that subject, just where would one put a temp sensor for monitoring,thermostat reading and fan triggering?? Cab ceiling?

This is what I was looking at installing, with one fan in the lower TV compartment and one in the receivers-

Thoughts?

$80 sounds way overpriced for two 120mm fans and external power supply.

Yea, that plus two automatic thermostats for two different zones. I could get it with out them and turn on/off manually, but I'm too lazy. But I guess as they say, "stupid is expensive" and that may apply to lazy too. LOL

I'd try plugging the fan into the switched outlet of the receiver. Fan comes on when the receiver is on.

At the very least, get a 2" hole saw and cut a few holes in the top and a few cool intake holes down low in the back.
Take advantage of hot air naturally wanting to rise.

Thanks for the suggestion Rick- unfortunately I don't have any outlets on my receiver....
But I do have a hole saw!!

I was just thinking about this last night myself. With my new a/v cabinet now having doors my Apple TV is roasting the rest of my components.

And before I start talking to the guys that sell these things , can anyone comment on their experience with the amount of noise generated by these 80, 92, and 120 mm fans. They give specs, of 14, 19 and 28dB respectively, but how audible is that?? ( ie in a quiet portion of a movie??)
Last thing I want is an annoying buzz in the background....
