Operating receiver (and rest of HT) at 90F room temp

My A/C is broken and my house temp is 90F. It may be 24 hours before it's fixed and we're bored and trying to find activities that don't require us moving at all (conserve body temp)... e.g. watching movies.

Is it going to be bad for my receiver (or any other components: speakers, LCD TV, DVD, PS3) to run at this room temp? All is well ventilated... my gut instinct would be to worry most about the PS3. However I was running receiver earlier and it felt pretty hot to touch.

Can't really find specs on any of this in the manuals.

Am running my PC with case wide open and desk fan blowing into case... EVEREST reports ok temps.

Well, I found in the TV, DVD, and PS3 specs they all say up to 95F is ok. The receiver doesn't have a number, I'll just assume it's ok too.

May be a little late to mention it, but the spec should also include a humidity tolerance. Without A/C, your house humidity will rise to meet ambient.

Probably obvious, but running heat producing devices will increase the discomfort level in your house by raising the temp even more.

I feel your pain. The HVAC guys are in my attic right now...upgrading my 14 year old systems for more efficiency/comfort before they actually break, so I'm voluntarily without A/C on one floor or the other for the next 3 days.

It would be some shitty design that couldn't operate at 90F -- a temperature that many parts of country and the world routinely see in the summer.

It's probably not as unreasonable a limit as you might expect. All consumer devices probably have a bit of safety margin built into the specs, but the real danger limit is going to based on the differential between internally generated temps and ambient room temp...the higher the ambient temp, the less easily it will convect heat away from the device. Humidity and air flow will also adjust the real problem temp for a given environment.

Something like a Linksys wireless router still only has an upper operating limit of 104°F and it produces much less heat than a piece of A/V gear. On the other hand, a Toshiba HD-A2 (had the manuals handy) has an upper limit of only 95°F despite having active cooling, but probably uses much hotter running chips and/or more of them. Without A/C, I have no doubt my theater room (FROG) could easily get to 95 or higher on a typical sunny summer day here in coastal NC.

Matt, your receiver probaby doesn't have an operating temp spec since it contains temperature protection circuits to shut it down if it gets too hot. Checking my Onkyo 805 manual reveals that Onkyo doesn't include temp specs either.

I just lay a small fan on top of my receiver to blow air into it to keep it cool.
