What's the max temperature should .....

polk500

Good day,

So I have all my equipment in a 5'x5x8' high room.

The components are sitting on heavy duty plastic shelves with plenty of holes for ventilation and are stacked with about 12" of space between each component.

As I'm running 3 amps and a AVR The temperature get to a max of 90 degrees in the room. I have a small fan under the stand blowing up to move air.

So the question is should I vent the room outside (it would be a pain in the butt but doable)

Now I don't think it's a problem as the BK runs hotter then 90 F not sure the exact temp. The digital gage I use only goes to 120 F
But I figured I would get some input from you guys.

Thanks

Roger

I'm a huge fan of keeping the temperature as low as feasible (70 degrees). All of the medical imaging equipment I work on, one of the biggest problems is overheating. We have monitors on the equipment that checks the equipment 24/7 to make sure we don't run into any heat issues. The temperature may be 90 externally but how high is it internally?

The inside of your parked car gets way hotter than that (90F) on a sunny day. Some listening rooms get hotter than that every summer. Sunshine through a window can heat an amp hotter than that.
Is the free air just above (say an inch or three) your components 90F or 120F ?

Thanks for the replies. I do appreciate the fact that the medical equipment needs to stay at 70. The BK runs hotter then 120 on top of the chassis how much I'm not sure as I had mentioned the gage I'm using only goes up to 120 so using the same logic if the ambient temperature is no greater then what the internal temperature is then I shouldn't have any problems.

As I have the fan on the floor (concrete floor) blown up over the equipment the gage resister 90 max at the 6 foot level. So I think even if say I vented the air outside I don't think I could drop the temp much. Even when the amps were in the glass racks in the living room you could feel the heat.

Ummm....air conditioning.

Yes that would work. But the wife would be pissed if I did and didn't put it in the rest of the house.

Don't do AC much in the frozen north. Probably only need it for a couple of weeks at most.

Your going to dry out the cap in the amps quicker if they are in a hot environment vs a cool one. I would aim to keep it 70 to 75 but that is just me and the fact that I hate replacing caps.

Roger,

90 isn't that hot to begin with and you already have a fan. No need to vent outside but given your location why not just leave the door open an inch or 2 ? You can also just cut a nice square hole at the top and just use a return vent cover or any vent cover to let air out.

Ductless ac or heat pump version. Heat pump built for running in lower ambiant conditions. Cheers.

Thanks for the replies,

That's what I done on the weekend.

Well I cut out two holes (6" x 10") one at floor level and one at the eight foot level and build a small shelve to place another small fan on.Warm air is exhausted out into the stairwell (as well as noise from the fan) and the vent covers look like they were always there.

As for the temperature;I was playing some tunes for a few hours and watched a movie on Sunday and it was between 78 and 80 degrees so not to bad.

And it costed me $38.00 and a couple of hours with driving to the hardware store and cutting out the openings.

Now I've got to figure out how to turn on the fan with my remote as right now I have to plug and unplug it.

Those fans draw little enough power that you may be able to run them from a switched outlet on other gear like an avr

Hey good idea I will check it out when I get home and see does it work.

Thanks

Well looks like I blew a fuse or something in my Harman Kardon 3600 switched AC outlet that i use to run a small fan. It was working fine up till last evening or maybe earlier as I don't go into the room everyday.

I read the manual and can't find anything referencing a fuse but one would think that there must be correct?

So my question; Is it a big deal to open one these AVR up and have a look and if I was what would I be looking for a glass tube type fuse?

Not a electronic's guy but its probably pretty easy and I don't like to spend money on something that's probably a easy fix.

Thanks for any suggestion.

Cheers

Did you try plugging a little light or something into that receptacle?

polk500

Yes I did.

Thanks

I should mention I've call Harman Kardon left a message 4 hours ago no response as of yet.

Roger

So as a follow up HK returned my call and said it was fused switch and he said it was buried deep(?) inside; and didn't recommend opening the AVR to fix it unless I was a experienced tech.

I will probably just leave the fan on all the time as it draws very little power and it is quiet.
Or maybe not cuz it will just bug the #hit out of me knowing something is not working!!

Well got a weekend project and if I can't fix it at least I will get a look inside of the unit.

As an update to this thread, I when with a fan from the coolerguys, it's controlled thermostatically so I have it set at 75 degrees works great.

I read about it on this site but I can't remember who started the thread.

Anyhoo thanks.
