When is hot too hot?

 

I have been enormously enjoying my “new” BeoCenter 9000 and while tidying up a bit noticed that the heat sink fins were warmer than I expected at approximately 110° F or 43° C.

 

I had been playing the 9000 for about an hour at “9” out of “15” volume.

 

A quick comparison check of my Beomaster 2400 after a reasonably hard work session produced nothing more than a “warm” 90° F or 32° C.

 

Both amplifiers sound great: no distortion, no malfunctions, nothing out of the ordinary.

 

So is 110° F or 43° C acceptable after an hour of play?

43° C is a nice summer day down here, so I dont think its too hot if it stays there.

Collecting Vintage B&O is not a hobby, its a lifestyle.

It will not win any green awards, but might make the music warmer.  :-)

Thanks guys, I get the picture. I really didn’t “think” it was a problem, but thought it best to ask. I really have way too much time invested in this BeoCenter to have it succumb to an over heating problem I ignored.

 

Your responses remind me of the OLD joke, “It is 102° in the shade today here in Sarasota, Florida…… so for God’s sake, stay out of the shade!” Paradise

My well-adjusted Beomaster 4400 manages to get up to just over 50 degrees Celsius under hard working conditions Wink

Hi Søren,

 

Thank you for sharing that helpful information.

 

In a different place and situation my Beomaster 2400 got plenty hot powering three pair of very inefficient speakers and I can well imagine it reached 50° C. Crying

 

However today powering S45 speakers and working really hard it gets warm at most.

 

The same is true of my own  handicapped Beomaster 4400; that said my 4400 reacts unfavorably to being pressed to play at a high volume so that might account for the difference in temperature.

 

In any case I regard this as very good news. Smile

 

Thanks for your impute.

My BS5500 was running very hot for a long time.  I'd set it up so that the left/right speakers were actually the front and back.  That meant I could adjust the front/rear balance from the remote but also meant that the amplifier wasn't balanced - they were different sizes of speakers.  Anyway, it must have been running like that for a long time but when I had friends round, one almost burnt himself placing a CD case down on top and brushing the heat sink with his hand.  All is well now that I've balanced the speaker sizes.
