GuyIsDamGood Posted September 21 Share Posted September 21 (edited) Hello I have the Yamaha R-N 803 and A-S2200. I recognized that both amplifiers will get warm on the Left Heat-Sink. (around 90 - 105°) Does anyone have that same warm left heat-sink situation with their Yamaha amplifiers or other brand amplifier(s)? Thank you Edited September 21 by GuyIsDamGood Quote Link to comment Share on other sites More sharing options...
babadono Posted September 21 Share Posted September 21 I have no experience with these but......is this not normal? If concerned I would get a hold of Yamaha tech support. Or at least Google for what is normal temp. 1 Quote Link to comment Share on other sites More sharing options...

I hadn’t noticed one side getting hotter than the other. 2 Quote Link to comment Share on other sites More sharing options...
billybob1 Posted September 21 Share Posted September 21 One should expect some heat by virtue of being a heat sink. Would contact the maker if any concerns there @GuyIsDamGood 1 Quote Link to comment Share on other sites More sharing options...
GuyIsDamGood Posted September 25 Author Share Posted September 25 (edited) (if there's any owners of the Yamaha R-N 803 or A-S2200 that's concerned of the Left Heat-Sink being warmer than the right heat-sink during play-back) I contacted Yamaha to ask why. Yamaha's reply: "most of the A-S2200 circuitry is on the left-side of that amplifier. It's the reason for the warmer temperatures compared to the right heat-sink. The amplifier is equipped with over-heat sensors; to safe-guard the amplifier. If the amplifier isn't shutting down; it's playing at a safe temperature." "the R-N 803 doesn't have symmetrical circuitry; the heat can be on the left heat-sink or right heat-sink". (I'm more concerned with the A-S2200 Integrated Amplifier. I'm going to allow more heat to escape the amplifier by raising what I have on top of it; by 3 - 4-inches) Edited September 25 by GuyIsDamGood 3 Quote Link to comment Share on other sites More sharing options...
parlophone1 Posted September 26 Share Posted September 26 The tech said it. Ut other factors count also. What is the surrounding temperature in the room?. For example, I noticed big differences in winter when room temp rarely go above 18 Celsius. Then the amps are barely warm. In summer temp can go up to 34 Celsius (no air conditioning). Then amps can get so warm I can barely touch them. Any way, leave enough room/air around the amps, do not put them in closet or similar. 1 Quote Link to comment Share on other sites More sharing options...
GuyIsDamGood Posted October 1 Author Share Posted October 1 (edited) I added another 2" (2-inches) of space between the top of the Yamaha A-S2200 and the CD player that's over it. The left heat-sink continues to run warm (105-degrees) and the right heat-sink (90-degrees). (I like to play the music at 110 - 120db - while in another room) - that could be the reason for the warm heat-sink(s)? I'll see if it'll run warm as/when the weather cools. (I'll check the temperature of the heat-sinks while playing music at 65 - 75db; to see if the lower volume will make a difference) Edited Wednesday at 09:59 PM by GuyIsDamGood Quote Link to comment Share on other sites More sharing options...
parlophone1 Posted October 2 Share Posted October 2 I don't think that lower volume will change much. Quote Link to comment Share on other sites More sharing options...
BRBNGUY Posted Friday at 04:37 PM Share Posted Friday at 04:37 PM I have a AS701 and AS501, and neither even get warm. but I play at reasonable volumes. Quote Link to comment Share on other sites More sharing options...
