Summer Heat Concern With DVRs

While I understand your concern as our prised DVDs are no longer made, you should be just fine I'd just let them be and if you have any scheduled events you should be fine. I've found the most head is generated during DVD burning so as long as you're not doing that when the temps are over a hundred, or even up to 110, you should be fine. The units should also have a cooling fan that runs off temp so if need be, the fan will start up. I guess if you had your equipment in a closed cabinet, maybe leave it open while you are gone.
You didn't say how hot you expect your media area to get with the heat off, over say 110F probably wouldn't be good for any type of recording but unless you live in a desert area I doubt things would get that warm.

Thank you very much jjeff. Outside (street) temperature could get into the 90s so indoor temperature w/o a/c would be at least that.. The equipment is in a permanently open closet. If I did any scheduled recording it would be only on the HDD, not on a DVD.

It sounds, from what you wrote, that it's best to avoid recording, probably to be safe even HDD. Would fans blowing on the units help or, as the air being blown is hot anyway, wouldn't make any difference?

As inanimate objects like a DVDR don't feel the effect of wind chill, and your equipment isn't in an enclosed area, a fan wouldn't really help. Again the DVDR should have a built-in fan that would come on if the heat exceeds a preset value so you should be good. Note I haven't opened up a DVDR of your exact model so the fan might just come on anytime the unit is ON and not wait for it to get warm but regardless HDD DVDRs should all have a small built-in fan, like most all computers.

I appreciate your replies, jjeff

My question about the fan was about increasing external air flow ventilation. A computer server room where I used to work had a large fan blowing on the servers. I thought (but not certain) it was for when the building a/c was off (e.g. weekends).

I understand your point about the DVR fan coming on if I scheduled a recording and the unit was on (running). But if, to be safe, I don't schedule an HDD recording, then the unit, though plugged in to a UPS to keep its settings, is "off" (not running). I would expect in that case when it's "off" the fan would never come on regardless of the heat level.

I'm not any kind of expert in this so I'm only asking. Thank you.

If your DVDR was in a confined space then yes, an external fan might help but because you said it's not, I don't really think it would make a difference. Not that it would hurt, other than the wattage of the fan adding a tiny amount of heat to the room.

Thanks jjeff!
