Yamaha R-N 803 and A-S2200 Left Heat-Sink

Recommended Posts

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

I have an R-N803. I hadn’t noticed one side getting hotter than the other.

(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)

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.

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)

I tried playing music for 1-hour and 1/2 (the temperature in the room was 70°) at 65 - 75db; to see if the lower volume would make a difference with the warm-temperature from the left heat-sink. It reached: 87° - 92° - the right reached: 82°.

 

Next time I'll try it when the room temperature is cooler.

not quite sure why you're worrying about this, especially since yamaha said it was normal.  just so you know, 105 degrees F is NOTHING.

I have my A-S1000 sitting on top of my CD-S1000 to help minimize vibrations.  Probably only minimal benefits due to the robust build of the CD-S1000 at 33.1 pounds.

Yesterday; I played the A-S2200 while the room was 61°- Fahrenheit (loud - 113db after three hours).     The left Heat-sink was 92°.     The right was 86°.     (the Rotel RB-1582 Mkii External Amplifier was cooler also)

 

It looks like the cool-room temperatures is probably the solution. . . . .(?)

To continue the unequal warm Heat-sink issue:

Yesterday; I connected (wife's Insignia NS-B4111 CD Boombox) to the Yamaha A-S2200. I was playing music for 5 hours at 110db. The room was 59°-Fahrenheit.

I checked the temperature of the left and right heat-sinks. (they were both 88°)

I played music on the Technics SL-PD8 (compact disc player) connected to the Yamaha A-S2200 (at the same 110db volume) and the heat-sinks reached got warmer (left reached 92° and the right reached 90°).

Anyone know the reason for this?
