Surprise! There are three fans inside the Yamaha RX-A8A! If you want to see the complete teardown, here is the video. \n\n\n\n\nThe first fan is above the processor. But where are the other two?\n\n\n\n\nThe other two are below the power transformer. Watch the video for complete teardown. It is not mine but I found it very interesting though I do not understand Korean.\n\nSweet!! I lifted the hood on my A4A, it's jam packed in there I couldn't get any good photos underneath the boards. As everyone that's researched the A4 and up there is one lil fan on top. I couldn't get any good photos from the sides.
