    Rotel power amp operating temperature

    Hi guys

    I have a Rotel RB1090, RMB1095 and RMB1565. It is normal for the 1090 and 1095 to be warm to hot while operating because of them being Class AB. All my amps are in a closed cabinet with improvised ventilation. The 1565 is cool throughout operation due to it being a class D. The 1095 and 1090 feels a bit warm which I find interesting as they are fanless and they are in an enclosed cabinet.

    Though this being the case I still would like to know what is the recommended operating temperature on this amps. I want to check the temperature after a long period of playing and check how far well I am within the recommended operating temperature.

    Any takers

      I don't know what the temperature is...never checked, but I know a rule of thumb is if it's uncomfortable to put your hand on it for a say like 30 seconds, it's probably too hot.

      My 1090 gets barely warm, now it's sitting out in the open with just a PS3 sitting on top of it., the 1095 definitely gets warmer than the 1090, but never uncomfortable. Best thing to do is listen to something for an hour with the doors closed... then with them open... if there's a huge difference (there will probably be some difference) then when closed they aren't getting enough ventilation.

      Only thing with running them too hot is you lose a little life to them, they are overall made to run warm and often don't sound their best until they get warmed up.
      Digital Audio makes me Happy.

          Rotel is pretty specific about the clearances needed for their amps in the manuals. They do not recommend ' stacking' at all. How tightly are they nestled into your cabinet?. Are they stacked in there as well?.

              Yes they are specific but one's situation does not always allow the recommended spacing. The recommended spacing is obviously for temperature control but you may be able to get away with spacing in smaller spaces with adequate or no adequate temperature control hence the question on this thread for me and others to know if we are within the optimal temperature

                  Lex, I know your runnning a simular set-up, could you tell me what your Asus Probe CPU temperature is at?

                  Currently mine is reading 57-60C @ 1898 mhz (13x146) This seems a bit high to me, however even at stock 2100+ XP speeds, the CPU reads somewhere around 55C. Core Voltage is at 1.75V....

                  Using the sensors of my cp-500, I noticed that up until now, its temperature was around 30 oC to 32 oC .
                  The last few days I noticed that the temperature is 35 oC when I turn it on, and it goes up to 38 oC after some use. The same thing goes with ca-2200: higher operating temperatures, feels...

                  Proceed AMP-2 & AMP-3 operating temps

                  Hi gang!

                  I've had my AMP-2 for 6+ years and love it. I just purchased an AMP-3 on eBay and received it this weekend. This paves the way to upgrade my HK AVR-430 with a Rotel ssp.

                  With my first couple of days with the AMP-3, I've noticed that it runs significantly hotter...

                  how warm do your amps get?
                  by stgdz
                  On a whim I decided to check out the temperature level at the top center of the heatsinks, the center base where the fin begins. The case top was taken off to get the best temperature. The amp is in an open air environment and not in a rack.

                  I recorded an average temperature at the...

                  I just moved in with my girlfriend last weekend. This is temporary until my HT-room...errr I mean house is built (it's still in the planning stages, it could take 3 years)
                  Unfortunately her house is not that big. The only place where I can put my 802s is in the bedroom.
                  The bedroom temperature...
