Hot RB 1080 *please help*

[asimov66]

I've placed my rotel as recommended by rotel but still it's hot to my opinion.

The placement is such that the sides are very close but there is a distance made with wood so there is absout 5 cm of air gap below and about 15 cm above and no front/back cover.

Still the rotel is about 46 degress celsius with no signal just standing there.
The temp is taken above the chassi holes with a digital thermometer.

Is there any problems with the heat and how much heat is to be concerned about I mean if the temperature raises to say 55 degress celsius is there a problem or how hot can this get without any problems?

Thank you very much in advance, I'd really appriciate any replies.

My general rule of thumb is if you can leave your hand sitting on top of the unit without pain, it's not too hot.

If you can't leave your hand there, the amp might need to be adjusted. Is there equipment below it?

I can leave the hand there but its hot about 46 celcius. Not burning hot but more than just warm. There is no eqipment below only wood i've put wood blocks under the feet themselves, to get more air in below the rotel. Air flow is important.

My 1080 is quite warm and I let another rotel 1070 sitting on top

For what it's worth, my 1080 never gets what I would consider hot. I'd say it gets warm. My RSX-1056 actually gets hotter right above the power supply. That being said, neither of them get near to the point where there is actually pain from resting your hand on them like Kevin D describes.

Do you run your amp pretty hard? I don't get the sense it's really crammed into a space so perhaps it's just normal temps for how you use it. Like Kevin D said, unless it's "really" hot, I wouldn't be too concerned. It's hard to imagine what 46 feels like, but my hunch is that it isn't too hot all things considered when dealing with electronics. Right now the temp on my CPU is 38 and I'm just surfing the net. I'm not sure it's really comparable to an amp, but the 1080 is a pretty strong amp that can produce allot of current and when it's being used hard, some heat is bound to be normal.

Thanks for the help, its really appriciated ;x( .
It's not superhot så I will not be so worried I guess.
I don't drive my amp hard at all.
Since it has all the airflow that is has I will just let it be for now.
Im just thinking about that old rule that says that heat makes electronics die sooner.

Thanks I will just let it stand as is for now.
Great, more time for playing music instead for changing gear :W

yeah mine gets up to about that temp too.

When it gets to the point where touching the heatsink leaves burned lines on your arm.

Then it is too hot. My RB-1080 hasn't ever done this, but a proaudio amp has.

Yikes . . . LOL

Yikes . . . LOL

It was about 100 degrees that day.

That didn't help.

[asimov66]

yikes that would be pretty hot that.
Nice to hear that more people has the same heatissue with the 1080

Try the wood blocks on the chassi not the feet. Use 2 blocks if you need more hieght for air flow. Get the feet out of the picture.

[asimov66]

will the chassi handle the weight of the 1080 if its not on the feet?

I always though that the chassi was streghtened to take the weight by the feet?

Is it not so?

What would be the difference on placing the wood blocks on the chassi not on the feet.

By the way now i have 5 bits for the feet would if be ok to but 3 strips of wood al the way to hit the 5 feet or should i give it a go with 2 strips on the chassi? will it not bulge or be twisted in the chassi, I mean the fifth foot is placed for a reson no?

so 3 strips on the chassi, a yes or no? pointers anyone?

The heat is between 43-46 degrees celsius and holding firm there.
