My yamaha used to get super hot when we pushed it, it was funny because it realaly depended on the movie you could watch some movies all day and others you play for an hour and you could smell the yamaha getting hot. That why I went with separates on this HT, I consider my first real HT system, I can play what ever I want as loud as I want with no issues, the amps stay cold no fans no smells, keep it on all day and it isnt even warm to the touch...
